"The Most Effortless and Scalable Scheduling Tool for Modern Teams"

5/5

What do you like best about Cal ID?

What I like best about Cal ID is how it combines ease of use with a surprisingly deep number of features that usually cost a premium elsewhere. The ease of implementation was impressive; I had my first booking link live and synced with my Google Calendar in under five minutes without needing a tutorial.

In my daily frequency of use, the ease of integration with tools like Zoom and Razorpay has been a game-changer, allowing me to automate both the meeting link generation and payment collection in one go. Even when I had a minor question about setting up a complex round-robin workflow, their customer support was responsive and knowledgeable. Overall, it’s a rare tool that feels both powerful for a team and simple enough for an individual to manage without any technical friction. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

While the core functionality is excellent, the user interface (UI) can occasionally feel a bit less polished compared to older competitors like Calendly. I have noticed minor lag when saving complex workflow automations, and I would love to see more advanced customization options for the booking page branding in the future. Better documentation for some of the more niche integrations would also be a helpful addition for technical users. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

Cal ID has completely eliminated the 'email ping-pong' game for me. Before using it, I was losing significant time coordinating across different time zones. Now, I just share my link and the software handles the time zone math and automated reminders. For my team, the round-robin feature ensures that leads are distributed fairly without manual intervention, which has significantly improved our response time and booking conversion rate.

"Effortless Scheduling and Professional Experience with Cal ID"

4.5/5

What do you like best about Cal ID?

What impresses me most about Cal ID is how efficiently it transforms the typical back-and-forth of scheduling into a streamlined, single-link booking process that maintains a professional feel for everyone involved. The interface is user-friendly, and features like calendar synchronization and automated reminders help minimize no-shows and cut down on the need for manual coordination. All in all, it makes scheduling seem effortless, yet still offers enough customization to suit various needs and client preferences. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

The main drawback I've noticed so far is that some of the advanced customization and workflow features seem somewhat limited, especially when attempting to configure complex routing or address more specialized needs. Additionally, certain settings are buried deeper within the interface than anticipated, which can make fine-tuning configurations more time-consuming than necessary. I've also experienced occasional delays with calendar synchronization, requiring me to manually verify availability to ensure everything is accurate. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

Cal ID streamlines scheduling by allowing people to book appointments directly through a single link, which significantly cuts down on the time spent coordinating over email each week. Its automated reminders and real-time calendar synchronization help prevent no-shows and double-bookings, keeping the schedule accurate without the need for constant manual oversight. With support for unlimited meetings and the option to host paid sessions, it also opens up new ways to monetize calls, all without requiring additional tools or complicated setup.

"Intuitive Scheduling with Great Integrations, Minor Room for Improvement"

3.5/5

What do you like best about Cal ID?

Cal ID stands out for its clean, intuitive interface and the way it removes friction from scheduling. Setting up availability, connecting calendars, and sharing booking links feels straightforward, even for teammates who aren’t very technical. The platform feels lightweight but still powerful, and it streamlines coordination in a way that noticeably reduces back-and-forth messaging. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

The main drawback is that some advanced customization options feel a bit limited, especially for more complex workflows. While the interface is clean, certain settings are nested deeper than expected, which sometimes slows down configuration. Additionally, occasional sync delays can require manual refreshes to verify availability. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

The most helpful aspect is how quickly it can be implemented across a team. Integrations connect without hassle, and automations work as expected right away. The ability to manage multiple event types, customize booking flows, and keep everything synced across calendars makes coordination far easier. It’s especially useful when meeting volume is high or when working with external partners who need a simple way to book time. Review collected by and hosted on G2.com.

"Perfect Free Tool for Managing Appointments Online for my team"

5/5

What do you like best about Cal ID?

CalID is extremely easy to use and completely free, which makes it stand out from many other scheduling tools. The interface is clean and intuitive, and setting up availability takes only a few minutes. Live chat support also helped with configurations, which helps to use it fluently. I really like how quickly clients can book appointments online without any back-and-forth emails. My team use CalID for daily meeting schedules and reminders. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

So far, I haven’t faced any major issues. Since the product is still growing, there is room for more advanced features and integrations in the future, but for a free scheduling tool, it works very well. Review collected by and hosted on G2.com.

"Effortless Scheduling and Seamless Calendar Sync"

4.5/5

What do you like best about Cal ID?

What I like most about Cal ID is how simple it makes scheduling. The interface is clean, fast, and easy to understand for both me and the people booking time with me. I also appreciate that it syncs smoothly with my existing calendars, which helps avoid double-bookings and keeps everything organized in one place. Creating different event types is intuitive, and the booking links look professional. Overall, it really reduces the back-and-forth that usually happens when trying to find a meeting time. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

The main downside is that some settings and customizations still feel limited or require extra steps to get right. Occasionally the interface can be a bit slow or unintuitive when adjusting availability or creating more complex event rules. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

Cal ID eliminates the constant back-and-forth of trying to find a meeting time that works for everyone. Instead of coordinating manually, I can share a single link and let people book based on my real-time availability. This saves time, reduces scheduling errors, and keeps my calendar organized. It also helps prevent double-bookings because everything syncs automatically across my calendars. Review collected by and hosted on G2.com.

"Effortless Identity Management with a Clean, User-Friendly Interface"

4.5/5

What do you like best about Cal ID?

Cal ID provides a clean and well-organized interface for managing identity-related information in one place. The onboarding is simple, and all key sections are easy to navigate without unnecessary steps. I find it useful that the tool supports structured profiles and quick sharing formats, which helps keep everything consistent. Overall, it’s a straightforward solution that reduces routine administrative work. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

The core functionality works well, but some parts still feel limited. I would appreciate more customization options for the profile layout and additional integrations with external services. Occasionally the navigation between sections could be faster. These are not critical issues, but improvements here would make the product more flexible for different use cases. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

Cal ID helps centralize personal and professional identity data, which eliminates the need to manage separate profiles across different platforms. It simplifies sharing links and contact details and ensures the information stays consistent. As a result, it saves time, reduces manual updates, and improves how I present my digital profile in a structured way. Review collected by and hosted on G2.com.

"The Ultimate Invisible Assistant for Effortless Scheduling"

4/5

What do you like best about Cal ID?

As a communication consultant, most of my work revolves around one-on-one coaching with founders, facilitating leadership offsites, and running small team workshops. Cal ID has quietly become my "invisible assistant," seamlessly keeping everything organized and on track.

What I appreciate most is the ability to create different event types tailored to my workflow—whether it's a brief chemistry call, a 60-minute coaching session, or a 90-minute deep-dive workshop with built-in buffer time for notes. Each event type comes with its own link, rules, and availability, yet all of them are consolidated into a single, streamlined booking page.

Setting everything up was incredibly quick. I connected both my Google and Outlook calendars, and my booking page was live within minutes. Real users often mention how smooth the onboarding and integrations are, and that has definitely been my experience as well.

From a communication standpoint, I really value the thoughtful details. Clients can book in their own time zone, which eliminates any confusion about scheduling. Automatic reminders have significantly reduced no-shows for longer sessions. Plus, I can accept payments for paid sessions directly through the booking flow, using providers that are more affordable than Stripe in some regions.

Finally, the short “cal.id/…” link is a nice touch. It’s easy to share in slides or mention verbally during workshops, and people actually remember it. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

Most of my concerns fall into the "nice to have" category rather than being true deal-breakers.

When it comes to branding and customization, I find the options somewhat limited. I would appreciate having greater control over fonts and layout, as well as the ability to use a fully custom domain instead of being restricted to the Cal ID URL. This desire for more design flexibility and custom domains is echoed by several other reviewers as well.

The interface itself is clean, but at times it feels almost too minimal. I found that understanding some of the more advanced workflow options required a bit of trial and error, and I've noticed that other users have also mentioned that workflows can initially seem confusing.

There are moments when calendar sync seems a bit slow, with a slight delay of a few seconds when updating availability. However, I haven't experienced any actual double-booking issues—it's more a matter of wishing updates were instantaneous rather than encountering a real functional problem. This matches feedback from other reviewers, who also point out minor syncing or UI/UX quirks rather than significant bugs. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

My entire professional focus is on fostering better conversations, yet before using Cal ID, I found myself trapped in frustrating meta-conversations. I was constantly caught in endless email and chat exchanges—"Does 15:00 work? No? How about Tuesday?"—and clients would sometimes arrive at the wrong time due to time zone confusion. On top of that, my afternoons were often double-booked because my personal and work calendars didn’t sync properly.

Now, everything flows much more smoothly. For discovery and chemistry calls, when someone reaches out after a talk or a LinkedIn post, I simply send them a single link. Cal ID checks all my calendars in the background, only displays my actual availability, and manages confirmations and reminders. This matches what many users describe: one link, no endless back-and-forth, and no scheduling conflicts.

For ongoing coaching packages with long-term clients, I set up a separate event type with a fixed cadence—weekly or bi-weekly—and built-in buffer time. The automatic reminders have significantly reduced the number of "sorry, I forgot we had a call" messages, which is especially important when we’re engaged in deep emotional or strategic work. Features like support for multiple calendars, automatic reminders, and buffer times are emphasized in Cal ID’s materials for therapists and consultants, and they fit perfectly with my communication coaching practice.

When I facilitate team workshops and internal trainings, I use a team booking page so multiple stakeholders can schedule time with me or an associate coach, rather than juggling separate links for everyone. Other reviewers have highlighted shared pages, routing, and round-robin scheduling as major time-savers for teams, and I rely on those same features for my group sessions.

For paid strategy intensives with global clients—such as one-off "communication audit" days with founders in other countries—I take advantage of Cal ID’s payment integration. Clients can select a slot and pay in a single step. Many existing reviews mention how valuable it is to accept payments from abroad and combine that with booking, and I’ve experienced the same benefit, especially when working with clients outside Europe.

The overall result is that I’ve eliminated almost all scheduling back-and-forth. My calendar is much cleaner, with fewer surprises and no accidental overlaps. I now spend more time preparing for meaningful conversations and less time playing "calendar Tetris." For someone whose work is all about making space for better dialogue, that’s a significant improvement. Review collected by and hosted on G2.com.

"Effortless Event Creation and Outstanding Support"

5/5

What do you like best about Cal ID?

I really appreciate how simple it is to create events and customize everything in one place. Setting it up took me less than ten minutes. The ability to add unlimited questions is especially useful for my client workflow. The reminder emails function smoothly, and I am excited about the upcoming WhatsApp reminders. I also enjoy the clean design of the booking page and the option to redirect people after they book. Their customer support has been excellent whenever I needed quick assistance. I’m also impressed by the seamless automation and integration with other apps, which is essential for my business now. This has definitely become my go-to tool for frequent scheduling ongoing client and lead calls. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

As someone who is still new to the platform, I find that certain aspects, especially on the backend, can be somewhat technical. If the interface were a bit more straightforward, I think the overall experience would be even more enjoyable. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

Cal ID has been instrumental in automating my entire scheduling process for my coaching business. It eliminates the hassle of manually coordinating call times, sending reminders, and collecting payments for paid sessions. The automated email reminders have significantly reduced no-shows, while the integrated payment option allows me to confirm paid meetings in advance. Additionally, the booking page efficiently manages all client information. Overall, this has saved me a great deal of time, keeps my workflow organized, and allows me to dedicate more attention to my clients rather than administrative tasks.

"Essential Scheduler for Remote Teams and Entrepreneurs"

5/5

What do you like best about Cal ID?

Perfect Tool for Remote Teams and Entrepreneurs

As a startup founder, I used to struggle with the chaos of managing meetings across different time zones. That changed when I found Cal ID. This tool is more than just a scheduler; it genuinely enhances productivity. Its seamless integration with various calendars and easy syncing have made it essential for remote teams. I also value the strong emphasis on UI/UX—it’s minimalistic but highly effective. Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

To be honest, I haven't encountered any drawbacks with this online tool so far. Their team is always proactive in addressing any challenges, from the onboarding process to managing the tool itself. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

Cal ID has eliminated the endless back-and-forth involved in scheduling meetings and dealing with different time zones. Previously, juggling multiple calendars was both confusing and took up a lot of my time. Now, with everything syncing smoothly in one place, I can simply share a single, streamlined booking link with clients or colleagues. This has saved me hours each week and made my workdays much more organized and less stressful. Review collected by and hosted on G2.com.

"Effortless Setup and Seamless Integration"

4.5/5

What do you like best about Cal ID?

The ease of setup and integration with my existing services (Google Calendar, and Microsoft Teams). I was up and running with my calendar page within only a few seconds (literally). Review collected by and hosted on G2.com.

What do you dislike about Cal ID?

Only a small thing, but it is prepopulated with services when you get started, which helps you to get a good understanding of how it works and how it will appear, but I then had to go and remove those services before I could put my own in place. Review collected by and hosted on G2.com.

What problems is Cal ID solving and how is that benefiting you?

Cal ID provides me with a public, bookable calendar service, with payments. Whilst Google Calendar has added a similar feature recently for higher paid tiers, the Google Calendar by itself is limited (such as payment providers). The Cal ID booking page has more customisation options to fit with my brand, and a wider range of (particularly more cost effective) payment providers rather than limiting me to Stripe which charge large transaction fees for transactions that they handle.

Cal ID provides me with far more customisation options that I ever had with Google Calendar, and far more out of the box integrations with everything automated messages to me and my customers, but also full automations through integrations with Make.com etc. Review collected by and hosted on G2.com.
