A UX pro recently asked me which I prefer most for design collaboration, InVision or Notable by Zurb. The truth is I love them both, for very different reasons and we use both regularly in our Design and Innovation department.
InVision is a tool that allows design collaboration and feedback on individual high res screens within a prototype.
The Graphic Designer on your team can make the changes you request using the Fireworks plugin and Dropbox, and they’ll display immediately in your project. It’s a pretty slick setup and is a fabulous tool to use for more detailed prototypes that you need to gather feedback on and edit before you present them or pass them to development with your wireframes.
Notable is the tool we use primarily for ux and maintenance reviews of both our mobile native apps and our web products.
Notable has a mega handy mobile native app that let’s you screenshot things straight to your account. We have a team account that can be broken up into projects.
I’m a big fan of their clean UI and ease of use. Instead of spending our time trying to figure out the tool, we’re in there cranking out review notations. We then pass these UX and maintenance Notable reviews on to our development team for coding. It’s a pretty solid setup.
In short, these are two fabulous tools and I really can’t pick a favorite because they’re both powerful in their own ways.

Good post. Trying to decide now between InVision or Notable for design collaboration.
I’m very partial to InVision. They just ramped up their feature set like crazy, I def recommend checking it out! (Disclaimer: I loved their product so much that I started working for them a month ago. haha But seriously… the product is ridiculously awesome.)
