Mac Platform: Intel

PhoneExpander is an app that runs on your Mac, just like iTunes. You connect your iOS device and are able to clear out space for updates, new apps, and media. It takes a few minutes to run, and you can use just one or all of the different tools. PhoneExpander is designed to be simple enough for your parents to use, but useful even for power users.
Clear App Caches (iOS 8.2 or lower):
There are lots of temporary files on your phone, wasting your space! In iTunes, they're simply listed as "Other", but they're impossible to remove. PhoneExpander can take them away without hurting your phone. Because of changes Apple made to iOS 8.3, this feature only works on iOS 8.2 or older.
Find Big Apps:
Easily see how much space each of your apps are taking and delete unneeded ones all at once.
Remove Huge Photos:
Pictures and videos often take up the most space on your device. PhoneExpander makes it easy to back them up to your Mac and then free up the space they were using.
