There are a couple ways you can calibrate your sunbathing session.
You can let Sola figure it out for you by turning on the switch by the “Max daily UV dose”.
The app will compute your sunbathing time to be as close to your “Max daily UV dose” as possible.
Another option is to either tap on “Current session” and select a preset duration.
Or use the “End” time picker for more flexibility.
You can then adjust other parameters such as sunscreen or flips to further customize your session based on your goals.
