FAQ
What factors increase sunburn risk beyond UV index?
TanMeter also weighs altitude, reflective surfaces (sand, snow, water), medications that increase photosensitivity, and time near solar noon.
Can I check burn risk for my children?
Switch to child mode and TanMeter applies stricter thresholds and shorter safe windows for pediatric skin.
What should I do if my burn risk is red?
TanMeter recommends postponing outdoor activity, using SPF 50+, wearing UPF clothing, and staying in shade during peak UV hours.
