Tanning App & UV Index - UVio

UVio is your personal sun and UV coach. It turns today's real UV forecast into simple, personalized guidance so you can enjoy the sun while protecting your skin. Set up your skin profile once, and UVio tailors everything to you. WHAT YOU GET • Personal burn-risk timer: see how long you can be in the sun before you're at risk, based on your skin type and the current UV. • Live UV index + 10-day forecast: real data for your exact location. • Best sun window: the lower-UV hours that are gentler on your skin. • SPF recommendations: how much protection to use right now. • Vitamin D guidance: a rough daily sun estimate for your skin • Skin tone estimate: a quick, on-device cosmetic estimate from a selfie. • Skin self-check reminders: a simple monthly ABCDE self-exam guide and log. • Weekly sun budget: track your cumulative sun exposure across the week. • Home Screen widget + Live Activity: your UV and burn timer at a glance. PRIVATE BY DESIGN Your skin profile, sessions and logs stay on your device. To fetch the forecast, only your location's coordinates are sent to the weather provider (Open-Meteo). No account, no sign-in, no tracking. IMPORTANT UVio provides general, estimated guidance to help reduce sun damage. It is not medical advice. Any tan from UV is a sign of skin damage, and there is no fully safe tan. Burn-time, SPF and Vitamin D figures are estimates. For skin concerns, see a healthcare professional.
