My favorite from version 1 – OutColor 2 Review

Amazing effects to create, only your fantasy to use. No analog for PC (except in photoshop you can make those effects,-but too complicated and timely) no Mac. Available only on IOS. Easy to use after little training and tutorials, check before say you can't use it. Again, it's easy, not Photoshop to learn, only little time and patience, and all your friends will be amazed :)
