FlipPad is the iPad version of the DigiCel FlipBook. It’s still pretty new but it’s getting better all the time. The in-app upgrade to FlipPad ProPro is the first animation app to support the Apple Pencil and the Apple Pencil really makes FlipPad shine.
It doesn’t have all of FlipBook’s features yet but it’s getting there and it’s priced accordingly. In fact, the basic version is free. In addition to Apple Pencil support, the in-app upgrade gets you the support for the Wacom Creative Stylus and the Adonit Jot Touch as well as more colors, more layers and more frames for only 2 bucks.
You can get more information and download FlipPad for iOS from the Apple App Store.
