"I'm pale as paper and SunTan got me to a real Warm Beige without a single peel. The timer-by-side thing is genius."
"The UV alerts saved my shoulders in Crete. The forecast view is the cleanest I've used in any weather app, period."
"Replaced three apps with this one. UV, vitamin D, routines — and it actually looks like something I want to open."
Absolutely not. SunTan helps you plan smarter exposure, but SPF stays the hero. The app even reminds you to reapply.
We combine your skin type, the live UV index for your location, and your recent sessions to estimate a conservative safe-exposure window.
Yes — SunTan is most useful in shoulder seasons when UV is sneakily high. Vitamin D tracking works year-round.
