Tan Alert tells you the one thing every sun-seeker wants to know: exactly when to step outside.
Instead of raw numbers, Tan Alert works out your best tanning window from the live UV forecast, your skin type and your goals — then shows it front and centre, in the correct local time for wherever you are looking.
