Android: Adobe has finally released the Android version of its Revel service (previously available only on iOS). The app allows you to store photos online, share private libraries with friends and family, and use Adobe's fairly powerful editing features to modify your pictures.
The app duplicates a lot of functionality that you can already get through existing apps, but having it all in one place — and from a company that knows a thing or two about photo manipulation — is quite handy. The editing features in particular are relatively powerful for a mobile app. It's not quite as powerful as Photoshop Touch for smartphones , but it's a good starting point.
