Full screen prototype viewer

It displays nothing. I thought its my link that has a problem, but when i checked on my browser it's fine.

Very very unexpected and not at all what I wanted. Please someone fix this.

Not, working properly. Quite frustrating time waster.

I tried this app but to my greatest expectation it did'nt workout well as expected.

Bad Application, not functioning well!

Plesently surprised and much better than xds actually app

Was never able to understand how to operate this app

This app is so frustrating
