Uh, this looks A LOT like InVision. Maybe too much.

Gravit is now a browser-based​ tool that you can access anytime, from anywhere and any device. Looks like a nice 2.0 release.

Was this the first? It certainly can't be now....

Wow this looks CRAZY like Invision. Landing page is almost a direct clone

I like the idea and concept a lot. I've been looking for something like this for a while, and am glad the interface is easy to navigate.

Gravit has come a long way since it's beta!
