Mockplus

This is a great design tool even it has cons of some aspects. I love it! You should give it a try and let more people know this great tool!

A perfect place for developer and designers to communicate and gather feedback.

Except no gesture for the mobile app, it's really a good tool for rapid prototyping. If you want a fast tool, Mockplus is great!

Navigate the entire design process in one place, act as the ultimate collaboration tool from design to development .

Keep designers, product managers and engineers working collaboratively and smoothly .

Group and manage teams and projects, set different roles to give members different permissions.
