Auto Auto-Rotate is an extremely simple app that stores Android's auto-rotate setting per app.

Do you usually disable auto-rotate and enabled it only for some apps? Like your gallery or your video app? Do you tend to forget to turn it off afterwards? Does it bother you?

Then Auto Auto-Rotate is the perfect app for you!

Auto Auto-Rotate is open source and released under the GPLv3 license[1]. Check out the code if you like[2].
