Hour-by-hour UV forecast for your location — today and tomorrow free; full 10 days on Premium.
Visual timeline of your tan journey — session by session, side by side, so you can track real progress.
Find the best tanning spots near you — beaches, pools, parks, rooftops — with directions, reviews, and one-tap calling, all within the T&T app.
Your tanning countdown on the iOS Lock Screen and Dynamic Island (Premium).
Step-by-step sessions with timed rounds, flip reminders and breaks — free with a 3-per-rolling-7-days allowance; unlimited on Premium.

Simple by design
Choose your Fitzpatrick skin type I–VI, or use the live camera preview to compare your inner wrist against the six reference swatches. No photo is captured, saved or uploaded.
See the live UV index for your location and a personalized tanning-time estimate that uses your skin type and selected SPF as context.
Run the countdown, with front-and-back tracking and a flip reminder. The estimate is a planning tool, not a guarantee against sunburn.
Why T&T
There are plenty of sun timers out there. T&T is the only tanning app that combines live UV data, dermatology-backed skin science, and Vitamin D tracking into a single, beautifully simple experience.
T&T uses the live UV index — the international scale maintained by WHO with WMO, UNEP and ICNIRP — as one input, alongside the Fitzpatrick phototyping system for personalizing to how skin tends to respond to UV. The result is a personalized tanning-time estimate rather than a generic clock.
No two people tan the same way. T&T uses your Fitzpatrick skin type and the SPF you're wearing as context alongside the live UV index, so the estimated session length reflects your inputs rather than a single generic rule. The estimate is a planning tool, not a medical prediction.
T&T isn't a burn-prevention guarantee — no app is. It gives you the live UV index, session context, a running timer with flip reminders, sunscreen-reapplication reminders, and session history so you can plan and look back at what happened, rather than just a real-time reading.
Apple Watch & Wear OS
Live UV index, your personalized tanning countdown, and a tap when it's time to flip — all on your Apple Watch or Android smartwatch. Set your session, then put your phone down. The Wear OS app is free and standalone; the Apple Watch app is part of T&T Premium.

T&T combines three inputs — your Fitzpatrick skin type (I–VI), the SPF you're wearing, and the live UV index for your location — into a personalized tanning-time estimate. That estimate is a planning tool, not a medical prediction, and it isn't a guarantee against sunburn.
T&T calculates an estimate of exposure-related Vitamin D from your session data — factoring in your skin type, the current UV index, and the body area you have exposed. It's an estimate, not a measurement of your actual Vitamin D level, and it isn't medical advice. Speak to a healthcare professional about your Vitamin D status.
T&T is a planning tool, not a medical device, and no app makes UV exposure risk-free. It gives you the live UV index, personalized session context, and reminders to help make more informed decisions about time in the sun. Always use appropriate sun protection, follow public-health sun-safety guidance, and speak to a dermatologist if you have skin concerns.
