Whether you’re looking to get that brilliant idea down, sketch or draw, Paper by FiftyThree is ready with a clean design. The app eschews buttons and menu items so you can focus on what’s important. Paper has the look and feel of a journal, but unlike real paper you can use two fingers to Rewind — no eraser mess here. iPad owners will appreciate Paper’s support for the highest resolution Retina Display (2048 x 1536 pixels) and an expressive ink engine that gives you a range of expressions from one tool. The Draw tool is free, but others like Sketch (soft-lead pencil) and Mixer (for mixing colors) are in-app purchases.
