I love Procreate. There are so many things I like about the app. 1. Unlimited color palates 2. Ease of switching between brushes

The UI is very easy to navigate, and it has a lot of tools that make drawing extremely easy. While there is a little bit of a learning curve, once you get the hang of the software (primarily with the use of tutorials), it's very easy to start putting pieces together.

Procreate by Savage Interactive is probably the best illustration app I've ever used. I want to say that Procreate was the first I started with and haven't left since, so there might be some bias. The options you have for different features like their lasso tool, the customization of different brushes, the ease of navigating the app it's all so good. Their support team seems excellent, and you get a transparent view of the app and their team through their content online. They are always releasing amazing features that keep pushing the bar, like their recent face paint tool to create facial recognition art. I had no confidence in the art that I created but Procreate removes a lot of the stress.
