More focus on the Product itself. I think I also do not require a Designer for the help before promptly put up my Mobile App onto Stores. For next I could get better control of the output rather than repeatedly giving instructions for my designer to edit and output. Next time before I want to submit another app, I could clone the template again. This back ups all my design into 1 place. ### 20.

Great for first time prototyper's **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Consumer Services | Small-Business (50 or fewer emp.) **Reviewed Date:** June 26, 2019 **What do you like best about Proto.io?** Proto.io has a great UX, it is easier to use that a lot of other prototyping softwares (e.g. protopie). Think of Proto.io as the Wix for prototyping, it has more flexibility than Marvel but functions slights worse (similar to comparing Wix and Squarespace). **What do you dislike about Proto.io?** It can be very laggy when using the app to build the prototypes. Also it doesn't flow as nice as other softwares mentioned: it is very much a number of screenshots with buttons to link them and some additional features (pop up windows) . **Recommendations to others considering Proto.io:** Use it as a first time prototyper to communicate your ideas. Marvel is probably better for people later stage looking for better flow and more functionality **What problems is Proto.io solving and how is that benefiting you?** It is great for first timer's looking to build their first prototypes to try and communicate to other what is in their head.

However, no other software that I'm aware of has the interactivity that proto.io has **Recommendations to others considering Proto.io:** Proto.io will really make your wireframes come to life! **What problems is Proto.io solving and how is that benefiting you?** Wireframing and prototyping that feels real. ### 29. bad experience **Rating:** 0.0/5.0 stars **Reviewed by:** Verified User in Food & Beverages | Small-Business (50 or fewer emp.) **Reviewed Date:** October 22, 2018 **What do you like best about Proto.io?** nothing I liked the best about this tool... customer service care only about your $ **What do you dislike about Proto.io?** DO NOT USE proto.io !!! еfirst of all - they have so many bugs... my developer and I had to contact customer service many times just to find out there are bugs and we need to change a few things... and it's just not worth it overall. There is a better services out there - just do your search. Also there is no way of exporting your project. I had a slight delay with going forward with my project and needed to pause my subscription - there is a "parking fee" every month. I have been a loyal customer for over a year and paid a lot of money over this period, then I parked it for a few months and still paid monthly "parking" fees... but when I realized I need to put the project on hold - until further notice proto.io customer service was not helpful at all - they said there is no way to back up the project and save it. we live in 21 century - the century of IT - task like this is so simple - they just want you to continue paying them.... If I cancel my subscription - my project will be deleted forever... the only way to keep it is to continue paying ... scumbags! think twice before start using them. **Recommendations to others considering Proto.io:** do not use it. period....

Good wireframe and prototyping tool. **Rating:** 4.0/5.0 stars **Reviewed by:** Raphael S. | Sócio-fundador e Produtor Executivo, Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2018 **What do you like best about Proto.io?** After testing many solutions for creating wireframes and prototypes, I found Proto.io. Because of its many features and integration between design and prototype of layers, using it I had the best user experience so far. It has many functionalities, like animations, layers and other features for high fidelity prototyping, but it's not difficult to understand, learn or use. **What do you dislike about Proto.io?** Altough its not difficult to use, the interface of Proto.io is a bit cluttered and it lacks space for the design-work on screens that are not so big. The pricing plans for more users are expensive. **Recommendations to others considering Proto.io:** If you are searching for a High-Fidelity protyping tool, Proto.io probably will be the better choice between the "low-cost" tools that can deliver these features. **What problems is Proto.io solving and how is that benefiting you?** I'm using Proto.io to make wireframes and prototypes for a cloud service that we are creating. It helps me think about my project because it integrates design ant prototyping tools and animations right inside the same interface. ### 31. Proto.io is absolutely unbelievable **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.) **Reviewed Date:** June 12, 2018 **What do you like best about Proto.io?** I like that I can easily create objects, and different screen states that will transition into a beautiful prototype that my developers can digest and then go and build. **What do you dislike about Proto.io?** The quality of the images in terms of exporting the documents is actually kind of poor. Some of the color pairings available in Adobe PS/IN/ILL are not possible in Proto. Proto is easier to use than adobe things so I've actually tried to make things in proto and export, however the images are very poor.... I almost wish there was more training in the beginning, but I've been using proto consistently for the last 90 days, and am struggling to think that far back. **Recommendations to others considering Proto.io:** Has alot of functionality, but not everything. Some things are harder to develop so that's understandable. It'll change how you design mock ups. **What problems is Proto.io solving and how is that benefiting you?** I can create my wireframes for a developer, let someone play with it, tell me what's wrong with it before having the entire thing developed. Saves a lot of time and money. Users can feel the prototype without using the full platform. ### 32. Proto.io Review **Rating:** 5.0/5.0 stars **Reviewed by:** Ansell L. | UX/ UI designer , Design, Small-Business (50 or fewer emp.) **Reviewed Date:** March 11, 2018 **What do you like best about Proto.io?** Proto.io has a lot of wonderful features for quick prototyping. The animations are a great buy, especially its is like designing an actual product. Even the export to HTML is a huge help for this product. I like the fact that Proto.io is a web product and not only restricted to the mac OS as many prototyping tools are restricted to mac OS which does not all alot of users who use windows to prototype. Another great feature is the integration of photoshop, where on can easily just import files and so easily prototype in Proto.io. Also Proto.io give you the freedom to customize your prototype for any particular screen of your choice and Proto.io is not just limited to web and mobile app. This has helped me alot especially when i do custom designs for prototypes. The layers option is really great which gives the user the freedom to move layers and groups around in Proto.io makes the user feel at home. Great going Proto.io love this product. **What do you dislike about Proto.io?** Nothing as of now, as there are soo many options and I do not find anything lacking so far. Maybe if they could also integrate Figma would be great. **Recommendations to others considering Proto.io:** Absolutely as this is the best software for prototyping. **What problems is Proto.io solving and how is that benefiting you?** Proto.io helps to make ideas come to life very very quickly and it helps for quick ideating, prototyping and iterations, it also helps to show prospective customers and clients our idea with a live feeling of the app. ### 33. Extremely flexible. The sky is the limit **Rating:** 3.0/5.0 stars **Reviewed by:** Josh H. | Co-Founder & CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** January 10, 2018 **What do you like best about Proto.io?** I love the fact of how incredibly flexible it is. You can even program movements in a way. I even created a synced countdown timer that would work even when clicking to a new page! **What do you dislike about Proto.io?** I wish they'd make the "programming" a little more dumbed down (it's not really like software programming; just for a lack of a better term). I also highly dislike the fact that they charge you to "park" your project when you're not using it. That's extremely lame. **Recommendations to others considering Proto.io:** It take some time to learn how to do the hard core stuff, but it's possible. **What problems is Proto.io solving and how is that benefiting you?** I'm able to make sophisticated app ideas come to life. People understand my vision better and can use something tangible. ### 34. Cloud based Prototyping tool **Rating:** 4.5/5.0 stars **Reviewed by:** Pankaj K. | Founder, Enterprise (> 1000 emp.) **Reviewed Date:** January 19, 2018 **What do you like best about Proto.io?** Strong prototyping capabilities of the platform not only you can design your prototypes with features available here, you can also build your interaction design with this tool. Being a cloud-based platform you can share your work easily with your remote teams to review or to edit it further - saves you time for using any third party sharing applications like Google Drive, Box, and OneDrive etc. **What do you dislike about Proto.io?** Being on a cloud the performance of the tool is directly proportional to your internet connection, people in remote or slower net connectivity may become frustrated with network outages. **Recommendations to others considering Proto.io:** For interaction designers and Prototypers, they should give this tool a try for one of their projects. If I had choice to recommend it to any client I would surely suggest this. **What problems is Proto.io solving and how is that benefiting you?** We have prototype many mobile app ideas for our clients and have quickly able to move into the build cycle for our clients. Using this tool has help our clients to improvise on their ideas faster and being a remote team this cloud based platform worked wonders for us. ### 35. Fantastic high fidelity tool with great customer service **Rating:** 4.0/5.0 stars **Reviewed by:** Sam W. | UX Designer, E-Learning, Small-Business (50 or fewer emp.) **Reviewed Date:** November 30, 2017 **What do you like best about Proto.io?** Sketch > Proto.io plugin. The ability to create high fidelity prototypes. Once you get how to use it, it's an extremely valuable tool that I would highly recommend. **What do you dislike about Proto.io?** The learning curve is quite high, and tool findability could be higher. It's occasionally slow with the Sketch import, and it would need to import sketch files as editable SVG's to be essential. **Recommendations to others considering Proto.io:** Sketch, Photoshop and Sublime text. **What problems is Proto.io solving and how is that benefiting you?** High fidelity user testing, quick and accurate feedback. It works with the design tools we use impeccably. It gives us the ability to seamlessly go from design > prototype > user feedback. ### 36. Good looking mock-ups made easy **Rating:** 5.0/5.0 stars **Reviewed by:** Joris A. | Co-Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** January 15, 2018 **What do you like best about Proto.io?** I like the ease of use and the power of this tool. You can build detailed and complex workflows using the online editor and then present the mock-up on a mobile device as if it was a real standalone app. My customers were amazed. **What do you dislike about Proto.io?** Nothing really. It takes some time to figure out the more advanced features but the video tutorials are verdy helpful. **What problems is Proto.io solving and how is that benefiting you?** I managed to convince my clients how a custom mobile app would create great benefits. In a couple of hours I had put something together that looked like a real app, including animation effects. ### 37. Really good app for mobile prototyping **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Design | Small-Business (50 or fewer emp.) **Reviewed Date:** January 10, 2018 **What do you like best about Proto.io?** Really good app for mobile prototyping - comes with mobile widget library for android and iOS - easy interaction features - community site with cool ideas posted and downloadable components - integration with sketch and photoshop - easy to share and demo for those who don't have an app (just send a url link generated) - they have an app to easily transfer the prototype to your device **What do you dislike about Proto.io?** Not good for advanced features like calculations or complex logic. **Recommendations to others considering Proto.io:** Great starter software for prototyping **What problems is Proto.io solving and how is that benefiting you?** Building prototypes of designs. ### 38. Prototyping with ease! **Rating:** 4.0/5.0 stars **Reviewed by:** Tim M. | Web Designer, Marketing Services, Mid-Market (51-1000 emp.) **Reviewed Date:** October 30, 2017 **What do you like best about Proto.io?** Static wireframes are quickly becoming a thing of the past. With Proto.io, I am easily able to create interactive wireframes for my current web design and development projects including animations, UX flows, etc. **What do you dislike about Proto.io?** Nothing so far. Everything is easy to use. I have not been able to try the Photoshop plugin yet, but I am sure it is just as easy to use! **Recommendations to others considering Proto.io:** Do not consider other services - Proto.io has everything you need! **What problems is Proto.io solving and how is that benefiting you?** Wireframes and UI/UX experience flows for client projects ### 39. Proto.io **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.) **Reviewed Date:** November 16, 2017 **What do you like best about Proto.io?** Proto.io is very easy to use. It's simple design interface was easy to grasp and functional. **What do you dislike about Proto.io?** Haivng to pay for a subscription is a bit of a hassle, but it's money well-spent as a developer. **Recommendations to others considering Proto.io:** Proto.io and inVision are comparable for making prototypes, but Proto.io is higher-fidelity and easier to use in an all-in-one software that's browser-based. **What problems is Proto.io solving and how is that benefiting you?** Quick prototyping and user testing is what I mainly used Proto.io for. It was easy to make changes and execute a high-fidelity prototype. ### 40. A lot of features and great for educational purposes and reviews **Rating:** 4.5/5.0 stars **Reviewed by:** João A. | Designer gráfico, Graphic Design, Small-Business (50 or fewer emp.) **Reviewed Date:** June 28, 2017 **What do you like best about Proto.io?** The review that you can gete from clients, heatmaps and video replay. **What do you dislike about Proto.io?** Some bugs that can be fixed, like the layers function in one of my prototypes this function doesnt worked at all. **Recommendations to others considering Proto.io:** Feedback from users is really awesome, and the intuitive construction of the apps interations are really great. **What problems is Proto.io solving and how is that benefiting you?** Prototyping apps in my case, customer and client review really quickly and precisely. ### 41. Great tool in a pinch **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.) **Reviewed Date:** July 11, 2017 **What do you like best about Proto.io?** I like that the user friendliness and the fact that it's frequently updated. It has a lot of interactions in the library and it's totally doable to fully prototype a basic app and make it look great. **What do you dislike about Proto.io?** It does not have all of the functionality that a tool like Axure has. It can also be problematic that it's web-based. **Recommendations to others considering Proto.io:** Don't expect this to be the end all be all of prototyping, but it is a great tool for moderately complicated apps. **What problems is Proto.io solving and how is that benefiting you?** I create an app that will be used by laundromats and it was very simple and easy to use. I was able to do this relatively quickly and hand off to developers. ### 42. Unlocks high fidelity but learning curve could be steep **Rating:** 5.0/5.0 stars **Reviewed by:** Mayank K. | Interaction Designer, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** October 24, 2016 **What do you like best about Proto.io?** The ability to prototype detailed interactions is very advanced. Their library of existing controls is very helpful when putting the pieces together in a prototype. The ability to export the final prototype into html, css and js is very helpful and works very smoothly when you try to add them on websites as part of portfolios or want to depict the interaction on a promotional page. **What do you dislike about Proto.io?** The learning curve in proto can be very high for certain types of interactions and might take a lot of time to conceptualize. This is the case only for very advanced interactions and might hold true for certain simple interactions as well. Layer and object management can be very tedious if the prototype is very big and spans multiple screens and elements. It very much depends on how many micro-interactions are present in the prototype. Considering this is a web client, sometimes working on interactions on the browser itself can be very slow and tedious. This is not a completely tool level problem. At several instances browsers tend to slow the system and hence, the client suffers as well. It looks like their recent improvements on the web client has improved speed and made it less heavy. **What problems is Proto.io solving and how is that benefiting you?** In terms of the business problems, the interactions between a designer and developer are becoming highly detail and specification oriented. The tool helps the designer indicate his vision in a very detailed manner and allows the designer to give an example of how things should look and feel in the final code. Proto achieves these requirements in a fabulous manner. While, there are certain disadvantages as mentioned above, they are true for specific instances. I expect very good things from the Proto team and they have taken strong steps to cater to designers. ### 43. Proto.io is a must! **Rating:** 5.0/5.0 stars **Reviewed by:** Kevin C. | Small-Business (50 or fewer emp.) **Reviewed Date:** July 03, 2016 **What do you like best about Proto.io?** What I really like about Proto.io is how well made it is. Not only is it easy to use but the amount of detail you can put into your prototype is insane! Not to mention that they have an app where you can pull up your prototype on your phone! How cool is it that you can just take out your phone and show your friend the prototype of your next project. **What do you dislike about Proto.io?** What I don't like about it is that sometimes it really starts to lag. Since there are so any features and things you can add to your mock up or prototype it starts to drag down the response time for basic functions of moving around the site. **Recommendations to others considering Proto.io:** If you are going to use Proto.io get ready to invest a lot of time in it. Not because it's hard to use or anything but because you will want to add "this" and a little bit more of "that". The best part is, is that your prototypes are only limited to your imagination. **What problems is Proto.io solving and how is that benefiting you?** I had to create multiple prototypes for client sites and any time they had revisions I would just make them on the spot before I even had my team get to development. It really helped me ave time and a lot...a lot of headache when dealing with my clients. ### 44. Advanced Prototyping Tool **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** August 07, 2016 **What do you like best about Proto.io?** Proto.io allows you to make aesthetically appealing mobile prototypes that mimic the functionality of a real application. It also allows users to add details and animation to prototypes. **What do you dislike about Proto.io?** It can be difficult to use and clunky. At times, it lags, which is extremely frustrating. Adding small details into wireframes can also take a lot of time. It took a lot of effort to prototype many screens. My team also had difficulties prototyping at the same time using proto.io when using the same account. If two people were working on different frames at the same time, one person's work would not save. **What problems is Proto.io solving and how is that benefiting you?** My team and I were wireframing and prototyping an Android application. Proto.io allowed us to select what type of mobile device we were prototyping for and had buttons specific to the OS that we were able to drag and drop onto our wireframe which was very convenient. ### 45. its great **Rating:** 4.5/5.0 stars **Reviewed by:** Jay B. | Business Analyst Intern, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** March 31, 2017 **What do you like best about Proto.io?** the prototyping options available is great **What do you dislike about Proto.io?** the limited 15 day trial period and then its expensive. Some times if the number of screens are high then it lags. **What problems is Proto.io solving and how is that benefiting you?** prototyping ### 46. Average Prototyping Software With Clunky Interface! **Rating:** 3.0/5.0 stars **Reviewed by:** Rohan V. | Senior Product Designer, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** April 20, 2016 **What do you like best about Proto.io?** It is a good software for mobile prototyping as it also allows to view the prototypes offline and natively on both android and iphone with a customised app icon. Also, it allows easy importing of the assets directly from Sketch and Photoshop which reduces the time in asset management to a great extent. One more thing that is great about proto,io is that it has a layer based stacking for the assets which allows for creating easy animations and better interactions. **What do you dislike about Proto.io?** I do not like the way it has been designed, there are a lot of options presented to the user on the main screen making the entire interface look too cluttered and also reduces the canvas space. Also, there ain't any mac app for Proto.io which does not allow one to prototype without internet. **Recommendations to others considering Proto.io:** It is a good tool for prototyping if there are multiple users involved and if you want to assign different level of access to each of them. Proto.io offers three levels of access i.e. "Designer"/"Admin"/"Reviewer". Also, if you want to create native apps that works seamlessly without internet than this is the tool to use. **What problems is Proto.io solving and how is that benefiting you?** I have been exploring proto.io for research purposes and for performing user testing with users in the academic projects. I really like the fact that I can use it on the mobile devices offline and it acts almost like a real app without much delays in interactions. ### 47. Easy to use tool for prototyping **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Higher Education | Enterprise (> 1000 emp.) **Reviewed Date:** July 10, 2016 **What do you like best about Proto.io?** 1. Mobile Element for quick mobile app mockup 2. Easy to use interface 3. Clear tutorial for basic function 4. Easy to review mockup on mobile phone 5. Automatic alignment **What do you dislike about Proto.io?** 1. Limited tutorial resource for advanced function 2. The mouseover interaction is not fluid 3. Slow loading speed for online prototype 4. Small canvas size for mockup 5. Unable to view website mockup in full screen **Recommendations to others considering Proto.io:** Nice for beginner for prototyping. But if you want to add some creative and fancy interaction. Proto.io might be a little limited. Also, the monthly pay is high if you use it consistently. **What problems is Proto.io solving and how is that benefiting you?** Verify the interaction and flow. Proto.iO enables me to quick make the mockup so I know the detail need to considerate when designing the flow. I can also easily sharet the prototype made on Proto. iO to hear the users' feedback. ### 48. Phenomenal Product! **Rating:** 5.0/5.0 stars **Reviewed by:** Andrew D. | Planning Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** June 11, 2016 **What do you like best about Proto.io?** Proto.io is probably one of the best software packages that I have ever used. It is very intuitive and I appreciate how much work they put into making this product incredibly easy to use. **What do you dislike about Proto.io?** The loading time of the previews is cumbersome, however that is dependent on your own project size and wifi speed. Not much to dislike here. **Recommendations to others considering Proto.io:** Keep doing what you are doing, and continue to make the platform intuitive and fun! Thank you! **What problems is Proto.io solving and how is that benefiting you?** Proto.io is a prototyping software and it does just that and it does it well. I have very little to complain and I suggest it to anyone trying to start a business of any kind. ### 49. Advanced mobile and desktop prototyping tool **Rating:** 4.0/5.0 stars **Reviewed by:** Elena M. | Senior Product Designer, Internet, Enterprise (> 1000 emp.) **Reviewed Date:** March 27, 2016 **What do you like best about Proto.io?** Proto.io gives a lot of freedom to create fully interactive prototypes. I find it extremely helpful for cases when your flow depends on complex gestures. Mobile prototypes work super smoothly, almost like a real app! **What do you dislike about Proto.io?** It seems a bit over complicated if you need a quick prototype. Takes a lot of effort to build high-level visual prototype using custom assets. Also it is kind of slow when you are working with multiple pages **Recommendations to others considering Proto.io:** Keep in mind that this tool requires some learning and not super easy to use. However, it does a very good job when you get used to it. **What problems is Proto.io solving and how is that benefiting you?** I built desktop and mobile prototypes for user testing. It turned out that this tool is much more handy for mobile prototyping, as it has so many gestures and native mobile interactions available. Too complex for simple desktop click through though. ### 50. Good for quick prototyping **Rating:** 4.0/5.0 stars **Reviewed by:** Qian C. | UX Consultant, Internet, Small-Business (50 or fewer emp.) **Reviewed Date:** March 20, 2016 **What do you like best about Proto.io?** I liked the seamless transitions and hover effects I was able to implement. I used a video playbook for my background and I was very happy with the outcome. Also, the drag and drop feature came in handy when considering aspect rations. **What do you dislike about Proto.io?** As of the last time I used it (Jan 2016), it was confusing to prototype long scrolling screens. It took me time to figure out that I had to set individual pages. The web app is also not very light weight so it gets a little slow when I flip between it and graphic editing programs. **Recommendations to others considering Proto.io:** Stick with the basics! **What problems is Proto.io solving and how is that benefiting you?** It is good for initial conceptions, but I would not use it for a heavier prototypes (with more screens, etc) ## Proto.io Discussions - [how do we do version control ?](https://www.g2.com/discussions/27210-how-do-we-do-version-control) - 1 comment - [When will the desktop application available?
