TanWise: Tan Timer & UV Index

TanWise is the tan timer that keeps working when your phone doesn't. Lock the screen, flip over, fall asleep in the sun: your flip and sunscreen alarms still fire, out loud, exactly on time.

THE TIMER YOU CAN ACTUALLY TRUST
Every session is scheduled up front as real alarms with sound, plus a Live Activity countdown right on your lock screen. The app does not need to be open. Your phone does not need to be awake. That is the whole point.

UV DATA YOU CAN CHECK
Your live UV index, hourly curve, and 7-day outlook come from Apple Weather, the same source as the iPhone's built-in Weather app. No mystery numbers.

MADE FOR YOUR SKIN, WHATEVER YOUR SKIN
A respectful six-type skin quiz personalizes your burn time, safe session length, and flip schedule. Fair, olive, brown, or deep ebony: every tone gets first-class guidance, with sunscreen factored in.

FREE FOREVER, AND WE MEAN IT
The tan timer, live UV index and hourly curve, best-time-to-tan window, audible alarms, today's vitamin D estimate, the home screen widget, Apple Health sync, and full CSV export of your data. No trial required, no lockout after a quiz, no tricks.

TANWISE PRO (optional)
- Your full sun history: calendar, rings, and trends, like fitness rings for sunshine
- 7-day burn-time forecast so you can plan beach days around your skin
- Family profiles with per-person guidance (great for fair-skinned kids)

Pro is offered as a weekly or annual auto-renewing subscription with a free trial, or as a one-time lifetime purchase; see the app for current pricing and trial terms. We will remind you before any trial converts, and the free features stay free either way.

PRIVATE BY DESIGN
No account. No ads. No third-party trackers. Your location is used only to fetch the UV index and never leaves your device; your data lives on your iPhone and your private iCloud.

Tan responsibly. TanWise provides educational estimates based on published UV science. It does not provide medical advice, and no app can guarantee you will not burn. Check skin regularly and talk to a dermatologist about your skin's needs.
