I made a pixel editor called Pixation for the iphone. I created it because i wasn't happy with any of the existing pixel editors so i made one exactly how i thought it should be... so obviously its what i use now to make pixel art on the go.

I made a free version with ads (sorry i had to put ads in it, im indie - I gotta live) but there is another paid version too with extra features for those who find it useful.

Also if anyone likes it/hates it/finds it useful i would welcome any feedback on it.
