Works great, No Frills

Works exactly how you would expect. Perfect for presenting prototypes to stakeholders from your phone. Excited to see how this app evolves!

In the future it would be really nice to have Wifi updating, but is definitely not a deal breaker. Great app!

Please fix “open in principle” integration with Safari

If I want to share a .prd file with someone to test a prototype they are unable to open the file in their Principle app. I want to share a link to the .prd via Dropbox. But when they download the file on mobile safari and tap “Open with Principle” under share, the file does not open. Impossible to share prototypes with team or testers.

Works great but doesn’t work over WiFi

Pretty frustrating since most apple laptops don’t have a USB port anymore. It would be great to support over WiFi
