We are implementing an ongoing process of evaluating apps, removing apps that no longer function as intended, don’t follow current review guidelines, or are outdated.

You will be asked to submit an update within 30 days to keep your app on the App Store. If you are unable to make the changes within this time frame, your app will be removed from the App Store until you submit an update and it is approved. Please note that apps that crash on launch will be removed immediately.

Apple sent an email to all developers today about App Store Improvements to encourage quality apps. If your app no longer complies with changes to guidelines or is buggy you’ll have 30 days to update it.

They additionally announced app names will now be limited to 50 characters to stop spammy names.
