Calculate how long sunblock SPF lasts for you!

SPF timer uses UV data from chosen location and your skin type to determine how long the protection lasts.
Set a timer and be notified 10 minutes before you need to re-apply.

Whether you use it to avoid sunburn and cancer, or to avoid wrinkles and to slow the aging of your skin: this app is for you.

SPF stands for Sun Protection Factor.

This app applies research on SPF, UV radiation, skin types and their time to burn, sunblock amounts typically used, and wear and tear of sunblock during the day. This is all used to give an estimated time a sunblock should keep you safe. Keep in mind that individual practice of applying sunblock will vary, and the estimated time could therefore be lower or higher than your actual protection time.
