If you have old apps in the App Store and I try to download a few of them they keep crashing when you try to open them and even can’t find them in the search option. So what happens and and what to do?
First of all almost all older apps work on the current iOS version pretty well. New iOS versions generally add new functionality to iOS, so it tends to be that apps developed with newer versions of iOS aren’t compatible with older versions – but when new iOS versions are released developers are supposed to test their apps to ensure that they continue to work, and if necessary make any amendments.
But apps only have a minimum iOS version specified in the store, not a maximum version, so if the developer hasn’t made any necessary updates to make it compatible with iOS 7 then it won’t work. Generally it’s the app’s developer that removes their app from the store, unless it’s found to violate copyright or store’s terms, or (I assume) if Apple get enough complaints about an app.
If you can find the app in the Purchased tab for redownloading then it should show in the main part of the store, and on its description page there should be a ‘updated date’ for when the app was last updated in the store (and there might be reviews) – iOS 7 was released in mid-September last year, theoretically any apps that weren’t compatible with iOS 7 should have been updated around that date onwards.
