Snapseed

This app is surprisingly good. It is easy to use, and not to mention satisfying. I like the variety with the number of options made for editing photos, and the fact that it doesn't take 12 hours to load like other apps. However, the only complaint I have with the app is that whenever you bring up certain menus you have to hold it then scroll up and down then release which picks the option you wanted. However, the menu just disappears. But thats about the only complaint I have.
