Before traveling abroad, enable Jet lag prevention and set Target timezone.
|Each hour of timezone difference requires a day of adjustment. If you travel e.g. 4 timezones away, start 4 days before the departure.|
Every night, during sleep tracking, the app will be intermittently flashing. We use 2ms flashes every 15 seconds.
The source of flashes will be the phone’s LED or a smartlight if you have it set up (see Smartlight to find out how to do that).
