As per my previous application review for photo-sharing service, the famous Instagram. I found another interesting applications in google play with the same point of view and focus, streamzoo.
Streamzoo provides more advanced photo-editing tools before you upload your arts. Unlike the instagram for android, it has 15 filters, borders, tilt-shift, more advanced lighting tools, and the best thing is you can choose how your photo sized to be uploaded. This what matter the most, unlike Instagram that force you to have a square picture to be uploaded.
