Such a great tool for mocking up high fidelity prototypes for testing. Works great when connected via USB to test on device, but it looks like the app has lost support for saving/opening the prototypes when not connected to your computer on iOS 13.Really hoping for an update that will fix the ability to launch prototypes untethered from your computer in the latest OS.

Buggy is fine, I’ll find another way and fix it. Transition not smooth is fine, at least it still work and I’ll reduce the complexity of my prototype. But I just don’t understand why the tab bar works terribly. Had to keep tapping it until it works. That is not ok at all. Tried it on a newer version of iPhone and it has a larger screen. When it’s not resized the tab bar works perfectly. Once it’s resized(the tab bar again is at the bottom of the screen), it doesn’t work anymore. Please fix it. Even though it’s buggy and slow (both this preview app and desktop app), I still think it’s one of the best prototyping tool. I really like that I can control the logic and make it like a real app. That makes it a great usability testing tool. Hope the team can put more effort on it and make it better for everyone :)

Besides jump right into Xcode, this is the best prototype tool to creat sophisticated mockups in fast speed. I am a power user, and see a lot of potential in this application. I hope the FB team could keep improving this, on performance, work with server etc.Can’t wait for the next update!

I use this app almost every day. Origami Studio is great as a standalone, but only this mobile app makes it possible to show your prototype to someone and get valid Feedback. Please continue to invest in it. This has Great Potential and a unique community. Would ❤️❤️❤️ if it was easier to create prototypes that adapt to different screen resolutions.
