Hide previous app store puchases!
I remember this subject coming up about your device storing all the app purchases that have been made on your device. Well just today, I read on AppAdvice that you can now hide those purchases (I found them annoying).
On the iPhone:
First, go to the App Store and tap the Updates tab at the bottom. Next you'll want to look for the purchased tab, just swipe left to right and a red hide button will appear. Tap that and you are done, the purchase is hidden.
On the iPad:
Now for iPad things are essentially the same with just one less step. As you know, iPad users have a purchased tab right at the bottom (no need to enter the updates tab). Just like on the iPhone, once you're in the purchased tab just swipe left to right on the app you want to hide then click the red hide button.
