When I delete a project using the iPad app in iOS7 it crashes and restarts my iPad. I have uninstalled and reinstalled, problem still there. This is making me wary of using the app now. IPad is the place I use this most and having subscribed recently I want the app to work, or I won't get the benefit of it. Didn't happen in iOS6.
Aside from that, app can also freeze up easily, even if it doesn't actually crash the iPad.
