    I have a Windows phone 8.1. I've installed this app, but it fails to launch. No error message, only the "Just a Moment" message. I've tried re-installing the program to fix the problem - had no effect.

    When I heard of this application I thought that there is finally a fix for the app development on mobile devices problem (first discovered on IOS) but as time went on using the app, it's lack of responsiveness and inability to scale itself and take user input correctly (you click one object 10 times correctly, only works when you click below it ( I am not talking about a script, but the entire user interface))realm made me have to take back my words... It looks like there isn't any sufficiently functional programming tool for mobile on mobile... Time to get xna or visual studio... 😞 by the way, I'm using a Nokia Lumia 530... 2mbps wifi

  • by mhmt 12/26/2014
    easy to learn and functional but i was unable to import my script in appstudio coz it lacks network support. also it has some visual glitches. and please add wp8.1 functions like file picker. then it will be perfect.
