I’m not a big fan of editing photos on the mobile as I never believed in the output. The ones that look good on the phone, before and after editing (especially on the iPhone!), doesn’t always look good on the desktop or when posted to Facebook. I was under this impression until I tried Colorify (from Asleroid).
It’s the single best ‘selective coloring‘ app that I’ve come across lately. I have been an Android user for more than 18 months, and recently moved to Windows Phone; never came across a decent app such as this on the Android platform.
I just tried coloring a couple of pics [see below]; turned out pretty good with no learning at all!
Install the app from here!
