What tools integrate with Proto.io?
If you need help choosing the right app prototyping tool, I created an article comparing the three most popular: Pronto.io, Marvel, and invision. https://www.enolalabs.com/blog/archives/best-app-prototyping-tool-proto.io-vs.-invision-vs.-marvel
I haven't used Marvel a ton, but I've been really pleased with them every time I have. The Dropbox integration is killer, and their animations are easy to use and look great. Marvel is best for something super quick. Plus they're free!
