This user friendly mobile app helps you track the time you should spend in the sun on a daily basis, for your body to synth size vitamin D. Available on both Apple Store and Android.

Track Your Sun Time


By authorizing your location and entering basic personal information about your skin type, Sun Keeper will calculate a sufficient and appropriate length of time you should spend in the sun. When your sun-exposure limit is reached, the app will alert and remind you to reapply sunscreen, cover up, or get out of the sun.

Sun Keeper offers recommendations that vary with the individual and are based on the personal information you enter along with your location, date, and time.
