App: Seashore
Developer: Robert Engels
Genres: Graphics & Design, Photo & Video

This is an easy to use but powerful image editor. It supports "layers". Imagine GIMP/Photoshop "light" - most of the features non-professionals need to create awesome images.

This incredible software is originally the amazing work of Mark Pazolli and many others (see the credits in the user guide).

The app is still open-source and is available at https://github.com/robaho/seashore

Enjoy!
