I’m having trouble downloading/installing the app/I forgot my password, can you help?

Kindly note that Apple (and not us) run the iTunes App Store and please visit http://www.apple.com/support/itunes/apps/ for further assistance.

The app is stuck in downloading mode, I can’t delete it or open it. What to do?

Try downloading the app when you have Wi-Fi access, not just 3G. Some of our apps are over 50 MB and can only be downloaded over Wi-Fi. Also try turning your device off and on again to resume download.

I lost the extra features/ad-free mode I bought as an in app purchase. Do I have to pay again?

No. Just upgrade the app again using the same iTunes account/password. You will not be charged because iTunes remembers all your purchases.
