Hi, I think there's actually quite a lot of differences between Atomic and InVision, so I'll focus on what I think the main reasons are that you might try Atomic if you're already familiar with InVision...

Atomic has drawing tools that let you actually design/layout interfaces in the app. You can also import flat images from other apps (like PS or Sketch) for prototyping if you want to. Atomic also lets you design complex and unique animated transitions, not just the standard ones on mobile.

Atomic has some other special features too: like being able to style elements with raw CSS, visually rewind through your history and make branches/variations from any point, and team collaboration that lets multiple team members work on the same set of designs, even simultaneously.

So lots of reasons to give it a try I think. I hope you give it a go and please do let us know what you think.

Looks nice. I'd also be curious to know the main differences between this and proto.io...

Lots of differences I think. Probably the main one is that Atomic's workspace will feel more familiar to those used to Adobe apps or Sketch. I think it'd be fair to say proto.io focusses more purely on prototyping, while Atomic tries to integrate design, prototyping, collaboration and version control tools.

Thanks; I'll probably take a look at it over the weekend.
