I have to say that I am impressed at mMbiroller.
All in all is a great app with lots of great functions. While it might not be always easy to make your app and then publish it to Google Play or the Apple equivalent, with patience I have now managed to do all of it and have an app approved for Google Play and also for displaying ads. During this "walk", it wasn't always smooth as I am new to this platform, however, I was helped by Mobiroller Support team and I must say that I would have never achieved what I have so far if it wasn't for Sefa and Team. Many thanks guys!
