I just discovered an app that single handedly made our entire iPad purchase worth it. It’s called Paper by FiftyThree. It’s a virtual sketchpad where you can write, draw, paint and sketch inspiration as you please. They have a blog with particularly good Paper sketches and inspiration. The only downside is that while the app is free, you have to buy the tools that aren’t the pen. Totally worth it though. Here is a quick video.
