FiftyThree’s Paper app for the iPad is one of the popular sketching app out there that lets you quickly take notes and create drawings. The initial version was rather limited with the colors section and the latest update 1.2.1(updated to 1.2.2 at time of writing) gives you a new color mixer feature. Mixer is both a color picker and a palette mixer that gives you unlimited color choice. The Mixer is priced at $1.99 as an in-app purchase.
Apart from that, Paper now has pressure sensitivity which supports the Pogo Connect stylus. Drawing, writing, and sketching with Paper now feels more natural than ever. Check out the video of the new feature below:-
