It records and syncs with your phone , no need to have them in proximity all the time.
There is a QR code for the correct app to install, there are many many apps with the same or very similar names, you need to get the correct one, for all features, some of the others will work but not as well.

Do you usually have to start an app on your phone or something? Or will it record and sync?
