Camera is terrible and borderline unusable
The app is fine for checking heart rate with the sock (though you’ll probably stop using this within a few weeks/months). But using the camera is terrible. It takes 1-5 minutes for the picture to load and you’ll have to repeatedly close and re open the app. There is a 5 second delay. The iPhone 15/16 camera notch takes up a good portion of the camera view. Sometimes you will look in the app and it is playing footage from much earlier at double or triple speed. Overall very disappointing
