The ability to re-download apps you’ve bought in the past is great, but if you’re anything like us, you’ve downloaded plenty of apps that you don’t actually use. Luckily, Apple has built in a super-simple way to hide those purchases, so they aren’t cluttering up your Purchased list.
To do this from an iOS device, simply find an app you’d lie to hide and swipe across it, and you’ll see the iCloud download button replaced with a red Hide button, which you can tap to hide the app. To unhide purchases, visit the account management pane of the App Store, and tap on Hidden Purchases.
You can also achieve this trick from iTunes on the PC or Mac by visiting your Purchased apps and hovering over the icon of any app you’d like to hide until a small x button appears in the corner; you can likewise unhide purchases by visiting your account settings page..
