I see that there is a general thread for iOS 7 & another for bugs within the OS, but I haven't seen one for collating App Failures. I'm using an iPhone 4S 64GB and the apps that I have noticed with problems so far, in alphabetical order, include: Startup Crash / Hang Ancestry Anodia Athlean-X Boost 2 CardStudio Connect Poker eBay EuroSport F1 Live 24 FS5 Hockey Google Translate IMDB PC-FAX.com FreeFax International Pinball Arcade Skill Game WikiPanion Menu Unresponsive Pong World Ringtone Designer Shock-X Wild West Pinball WindUp Knight Lost Game Save Data Tap Tap 4 Tap Tap Tour Other Issues Airbnb - latest update v 2.5.6 has no rental values or map info on properties App Store - randomly crashes during app updates iBooks - no books / PDFs showing even though they are on the device News Republic - was working very well until update 3.1 – now it crashes reasonably frequently Shazam - won't close properly, even from Multitasking. Had to DFU phone to close it Skype - overall works ok, but crashes when opening recents list and messaging TED - GUI layout issues Yelp - works fine except that you can't add Photos from the Camera Roll YouTube - seems to work except for the "share" options. When clicked, nothing happens. Personally I'm impressed with the stability and level of app compatibility considering we're at Beta 1 stage. The only one from the list I would struggle without is eBay which is accessible through a Web App anyway, so no big deal. Hope this helps, feel free to add more app issues you discover.
