Your best tanning window, front and centre
Most weather apps give you a UV number and leave the rest to you. Tan Alert does the working out. It combines the live UV forecast with your skin type and your goals, then shows the one thing you actually want to know — the best time to be outside today — in the local time of wherever you are looking.

Built around your skin
Set your skin type by holding your phone beside your skin and tapping the closest shade. Then choose your target UV level, your clothing and your SPF. Every recommendation is tailored from there: how long is safe, when to cover up, and whether conditions are actually worth going out for.
Tan smarter, not harder
Tan Alert isn't about getting more sun — it's about getting the sun you want without the burn. Safe-exposure timers and on-time sunscreen reminders do the remembering for you, so you can enjoy the day.
