Pull to close interaction

Lately I've been experimenting with ProtoPie for prototyping. For the most part it's really great; I'm finding it easy to use while also offering way more control than Principle. Even better, it's cross-platform, and you can also share prototypes in the browser. Definitely worth checking out if you're interested in doing prototyping for Android or want a tool that fits somewhere between Principle and Framer.
