Adobe Photoshop Express A good solid image editor that while has the Adobe Photoshop name attached, isn't quite up to par with the software version. However, you can quickly crop, fix, edit and share photos from your phone's camera.

PicsArt - Photo Studio This is a super fun photo editing app with a whole lot of capabilities. You can get really creative with the drawing tool, stickers, effects (water color, sketcher, pastels) and a lot more. It also comes with it's own camera and photos are easily shareable on all of the other social platforms.

Pixlr-o-matic If you like filters, effects, overlays and borders, then you will absolutely love this app. Recently voted best in it's category, and I tend to agree. These really make your photos look cool.

Photo Grid - Collage Maker Not so much a photo editor, but still a pretty neat tool for creating interesting photo collages. it's very easy to use, and the results look great!

PhotoWonder Decent app that covers all the bases from filters to effects and collage to frames. It works well and is a nice all around photo editing solution. The pics do come out a little small, however.
