UV Alert: UV Index & Timer

UV Alert is the free UV index app that gives you a clear "safe to be outside now?" answer at a glance — plus a sunscreen reapply timer, a home-screen widget, and a morning high-UV alert. No subscription. No paywall on the basics. No tanning gimmicks — just sun safety and skin protection.

Most UV apps bury the real number behind a paywall or lock the widget and reapply reminder behind a subscription. UV Alert keeps the parts you actually use free, funded by light ads.

WHAT YOU GET

• Safe to go out now? — a glanceable verdict
See your current UV index by GPS location, plus a clear go-or-protect answer built for checking outdoors at a glance.

• GPS-accurate UV that refreshes on your real location
No more "shows a town hours away." Reliable current UV, updated for where you actually are.

• Free home-screen widget
Your current UV, always up to date, right on your home screen — the feature other apps lock behind a subscription.

• Sunscreen reapply timer with reminder pings
Start the timer and get a ping when it's time to reapply (every ~2 hours). Never miss a reapply again — free, not paywalled.

• Morning high-UV notification
A morning heads-up on high-UV days that matches the in-app hourly curve exactly — no more "6 vs 8" mismatch alerts.

• Today's hourly UV curve
See how UV rises and falls through the day so you can plan around peak hours — tuned for extreme UV, including Thailand's year-round UVI 11–14.

BUILT FOR SUN SAFETY

UV Alert is for people who want to protect their skin — parents, runners, commuters, and anyone who's outdoors during the day. It is a sun-safety and skin-protection tool only. It is not a tanning app, and it does not provide medical or health advice.

FREE, WITH LIGHT ADS

No subscription. No paywall on the widget, the reapply timer, or the morning alert. Just a clean, fast UV app supported by light, unobtrusive ads.

Whether you're in Bangkok under year-round extreme UV or checking the forecast anywhere in the world, UV Alert helps you decide when to cover up, when to reapply, and when it's safe to head out.
