Minor effort in oder to create an app from a wordpress installation. Just some problems while trying to upload the app to the app stores, but everything solved thanks to mobiloud support. But the idea of having my "native app" solved in a couple of weeks was amazing. Still working on it after 7 months and no problem found on the app. Really helpful for our needs.
Price is a bit expensive, but regarding that on this side you don't have to do much in order to have your app up and going, you just don't mind spending it. You always can work with a developer that can do this for you in a custom way, but you will need a lot of time and much more money to spend. Maybe the app speed can improve a bit, and some customization options could be a bit more interesting. This is something that could give a developer more tools to work and impress the user.
If you'd like to have your app online using your wordpress as front and backend, you just need to consider using Mobiloud.
We were able to create an app for a client in a very short period of time and low budget, just using a wordpress installation on responsive mode supported by mobiloud to create the native app. Once uploaded it was really easy to administrate not only content but user registration.
