the Fitbit mobile app
Sunbathe app calculates the approximate time for sunbathing matched to your skin type, UV exposure, and sunscreen protector used. To use the app please read and agree to the disclaimer. This is a paid app. You have a 2h trial. You can unlock the app for 1.99$ + local taxes.
To use of Sunbathe app set 4 key parameters: your skin type, the UV index, and UV magnifier, and the sunscreen protection factor used on your skin. Based on those 4 variables the app estimates the maximum daily duration of sunbathing before sunburn occurs. During sunbathing the app will show 4 alerts: after 15' – a suggestion to apply sunscreen, every half an hour a reminder to drink water and check your skin, a suggestion to stop 60' before the time is up and final warning 15' before the time is up.
