Sorting iPhone/iPad Apps based on usage? [duplicate]
Solution 1:
I haven't seen any Spotlight metadata that counts the number an app is launched, you can, however, use the Date Last opened as a reference.
Open your /Applications folder and right click on the sort bar (where it says name, date modified, Size, etc.) and select Date Last Opened. Click on that to sort by that column and that's as close as you can get.
If you're feeling fancy, you can create a smart folder that only shows the apps that you've opened in the last number of days, weeks, etc. :)
Solution 2:
No, this isn't a native feature.
As of a default installation on iOS 6, this isn't possible. Like you mentioned, desktops in OSX can automatically re-arrange due to use, but iOS does not include any features along this line.
I would really enjoy this feature. You could always recommend this to Apple.
Solution 3:
The iOS multi-task bar (double tap on the home button to bring up) displays apps in the order they were last used. Not a frequency sort, but a last-used sort, which may be closer than your icon arrangement to frequency-or-use, and thus possibly a quicker way to find an app you use frequently.
