Character Maker is a series of drawing apps. There are a few apps in the collection, including instructional apps for kids, pixel art, and and a general tutorial app. Drawing is doable with a finger. However, these are much easier with a stylus. The apps include a ton of tutorials, The apps range in price from $1.68 and $3.68. However, they don't have any in-app purchases or ads to otherwise bother you. They all make for great stylus and S Pen apps.
Google Handwriting Input is one of many handwriting keyboards. These are perfect stylus apps. They let you write your messages to people through the usual array of messaging apps like Facebook, WhatsApp, Hangouts, and others. Google's Handwriting Input app is a decent option. Many other keyboards have them as well. Samsung's stock keyboard has this option too. That makes it great for S Pen users as well. Most of these apps are free.
RoughAnimator is an animation app that lets you animate actual moving pictures. The way it works is you draw something, then add a frame and change things up a bit. Once you’re done, you have a little animated movie. This is one of only a few apps capable of doing this. It has specific features for stylus users and direct S Pen support. You can export animation to QuickTime video, GIF, or an image sequence as well. It’s a surprisingly good app despite its lack of popularity. It’s one of those stylus apps that are worth a shot.
