Dapp the App Creator - for iPhone and iPad App Reviews

Its well though but how do you scroll the screen when testing the app out? Also how do you play videos on the movie player? Can you please help and add something about what these are about? Please?

Great App to build apps on the go, but impossible to creat new apps without the app update. This app needs to get updated with a fresh set of tools. Still love the app though !

I want to build apps but I dont know how to can someone help!!??
