It's not bad, but all you're doing is rubbing your finger on a screen for half a minute goin, "ooh! Pretty colors!" But you can only use 3 freaking colors which are green, red, and blue. You can draw so much with 3 colors. And the sparkles are huge and not even that sparkly. God, this app must have taken the creator about 5 minutes to make. No offense, though, creator guy.
