It's a good tool for designers. But the accessibility to a project's prototype using internet makes it a bit inconvenient for users. Every time I need to download the project(using internet connection)to show prototype!! Also the transition between screens is too slow.
Overall this tool has great functionality, however the performance really suffers on the Android app compared to the iOS version. If they're able to resolve that, this would easily be a 5 star app.
Just brilliant As a designer for me it helps a lot..
Usable but could be better If there was a way to toggle on/off the persistent Android nav buttons at the bottom, that'd be great. [Edit] I should elaborate, and say that my problem was with my prototype not fitting to the full width of my screen when I viewed it on this android device (Moto X 2014) but it's fine on iOS. I'm left with black bars each side, and like I said it's because of the persistent Android nav buttons. I have used apps that go full screen, so it should be an option here too.
Lagging I love proto.io, but my main testing device is Android, and the animations and transitions are slow and lag constantly in one place or another :(
So many errors So many errors and bugs make ot very risky to rely on this website to do your project. It might suddenly stop running properly without reason.
Added support for https://spaces.proto.io projects
Added "Show hotspot" option in project viewer
