With this app you can paint with your finger.
Thanks for all the support of you people :) Have a nice day.
I changed the default settings to random color and shaded "brush". You can change the brush and color anytime in menu.
I added location based analysis for a cool feature that I'm currently working at. Please forgive me to collect anonymous location data. Not doing anything fancy with it yet though. You can check out the source code since it's an Open Source Project and can be cloned at https://github.com/kibotu/android-painter
