UV Wiz tells you one thing, beautifully: how strong the sun is right now where you are — and how long your skin can safely enjoy it. Open the app and instantly see your live UV index as a big, color-coded number, from calm green to blazing violet. No menus, no setup, no account. Just the answer you need before you head outside. WHAT YOU GET • Live UV index for your exact location, updated in real time • A clear WHO category — Low, Moderate, High, Very High, Extreme — with matching colors • Estimated safe time in the sun for unprotected skin, tuned for Indian skin tones (Fitzpatrick IV–V) • Today's peak UV so you can plan around midday • Simple, practical protection advice for the current level DESIGNED TO BE GLANCED AT One gorgeous screen. Pull to refresh. The whole interface shifts color with the UV level, so you grasp the risk before you even read the number. PRIVATE BY DESIGN No account, no ads, no tracking. UV Wiz uses your location only to look up the UV index, and shows a default city if you'd rather not share it. ACCURATE, OPEN DATA UV readings come from the Open-Meteo air-quality service. The safe-exposure time is an educational estimate based on the UV Index and a representative skin response — it is not medical advice. Always use sunscreen and sensible sun protection.

Know if it's safe to be outside right now — at a glance. UV Alert gives you a clear, GPS-accurate read on the sun over your head and a simple answer to the only question that matters when you step out the door: is it safe now, or time to protect your skin? Built for people who actually go outside — parents, runners, commuters, anyone who cares about their skin. Not tanners. This app is sun-safety and skin-protection only. WHAT YOU GET — ALL FREE • "Safe now?" verdict — the current UV level plus a clear go-or-protect answer, built to check outdoors in one glance. No number buried behind a paywall. • GPS-accurate UV that refreshes on your real location — no more seeing a town hours away. • Free home-screen widget that stays up to date — the exact feature other top apps lock behind a subscription. • Sunscreen reapply timer with reminder pings — start it when you apply, and we'll nudge you for the every-two-hours reapply so you never forget. • Morning high-UV notification that matches the in-app curve exactly — no more "6 vs 8" mismatch alerts. • Today's hourly UV curve — plan around peak hours, tuned for extreme year-round UV. WHY WE BUILT IT Most UV apps paywall the two features people want most — the widget and the reapply reminder — or bury the number behind ads and upsells. We flipped it. The basics are free, funded by light ads, with no subscription and no clutter. MADE FOR THAILAND, WORKS WORLDWIDE Thailand lives under extreme UV (index 11–14) nearly all year, yet the number is buried in the built-in weather app with no reapply reminder and no morning warning. UV Alert is Thai-first and English-ready, with the widget + reapply + alert bundle no other app owns here. Your device language is used automatically. SUN-SAFETY ONLY We help you protect your skin — never tan it. No tanning tools, no medical or health claims, no vitamin-D tracking bloat. Just clear, honest UV information and a reminder to reapply. FREE, HONEST, NO SUBSCRIPTION Light ads keep it free. The features you use every day are never paywalled.

Verdict
The clearest difference is ads: UV Wiz at none against UV Alert's shown. UV Alert's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
