It works great for me! Just wish it had more settings for the device.

The app works great and no lagging or closes on me. I am using an iPhone 6s plus and it works perfect. Logging on Facebook its annoying but you can skip that instead of logging everytime! Maybe if they fix the view mirror so it wont look as bad it would be better but whatever it does the job of seeing what I am shooting. Maybe make an application for editing videos from the yi action cameras and shared directly to instagram,Facebook will be great! Keep making progress with the app! :)
