So I’ve had this “Brushes” app for a while now, and I think it may be the best drawing app in the app store. It has a nice brush selector with a spacing option. It also has a very good color picker with options like brightness/darkness, transparency, and shortcuts to black and white. (which I use very often.)
What really makes this app great is that it has layers. You can have up to 4 layers, and it is really easy to manage them. There are a ton of awesome techniques that can be done with this app.

Here are some pictures I have made from scratch with this app:

Also, another thing is that if you go to the address that it tells you on the app, it can take you to a bank of all your drawings, (If you have your iDevice on) and with the Brushes app for your computer, can fast-replay you drawing them.

This app was $4.99, and I’d say it’s worth it if you like drawing or want to draw. 🙂
