Read the guide →Frequently asked questions
What UV index is best for tanning?
A UV index of 3–5 (moderate) is the sweet spot for building a gradual, even tan with less burn risk. UV 6–7 tans faster but calls for shorter sessions and diligent SPF. SupaTan reads the live UV for your exact location and converts it into a session length for your skin type. Learn more →
What is the best time of day to tan?
Mid-morning (10 AM–12 PM) and mid-afternoon (3–5 PM) usually give effective-but-gentler UV; 12–3 PM is peak intensity, best kept short. The real answer changes daily — SupaTan calculates today's best window from the hourly UV forecast automatically. Learn more →
How long does it take to get a tan?
Most people see visible color after 1–2 weeks of short, consistent sessions — typically 10–30 minutes each depending on UV level and skin type. SupaTan personalizes each session's length and logs your progress in photos. Learn more →
How do I get an even tan without tan lines?
Flip on a schedule so every side gets equal sun — patchy tans come from losing track of time on one side. SupaTan's timer tracks which side you're on and taps you exactly when to turn, on iPhone or Apple Watch. Learn more →
Can you tan with sunscreen on?
Yes — SPF filters UV, it doesn't block all of it. You still tan with sunscreen on, just gradually and with far less burn risk (and a burn ruins a tan). SupaTan recommends today's SPF and reminds you to reapply. Learn more →
Can fair or pale skin get a tan?
Most fair skin types can build gradual color with short sessions at moderate UV plus strict SPF — many short sessions beat one long one. SupaTan's skin quiz tunes every recommendation to your skin type. Learn more →
Does SupaTan work on Apple Watch?
Yes. The Watch app shows live UV and today's best window, starts and controls sessions from your wrist, and delivers flip reminders as haptic taps — leave your phone inside. Learn more →
How do I tan faster?
Use your location's strongest safe window, flip on schedule, exfoliate first and stay consistent — never burn, it forces your skin to start over. SupaTan surfaces a "Fast Tan" window every day. Learn more →
