UV Alert
Read full descriptionHide full description
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.

Whimsy Weather

Whimsy Weather draws the weather instead of tabulating it. The top half of the screen is a hand-drawn landscape under a real sky. The Sun and the Moon are where they actually are for your latitude and the time of day, the Moon shows its true phase, and the rain, snow, cloud and wind in the picture are the ones in the forecast. The bottom half is the numbers — feels-like, humidity, wind, pressure, visibility, UV, sunrise and sunset, moonrise and moonset. A SKY THAT IS ACTUALLY THE SKY Sunrise, sunset, twilight and the midnight sun are computed, not faked. At 64°N in June the sky never goes fully dark, because it doesn't. Drag the timeline and the Sun and Moon glide along their arcs as the light changes — or tap an hour, or a day in the five-day strip, to jump there. SIXTEEN LANDSCAPES, ALL OF THEM ALIVE Hills, farm, city, beach, harbour, open sea, mountains, desert, lake and the tropics — and every one has something in it that the wind moves. Smoke leans downwind, the windmill turns in proportion to the wind, palms bend and coconuts fall above 60 km/h. People wander through: walking the dog, chasing a hat in a gale. SIX PLACES THAT READ THE WEATHER Taipei 101 shows the cloud base by which floor disappears into it. Fuji puts the freezing level on a cone of known height. The Golden Gate's 1,280 m span is a ruler for visibility. The Eiffel Tower's fountains lean in the wind, and drain in a frost. Liberty stands in water that turns to pack ice. The Pyramids cast the Sun's bearing and altitude across the sand. FESTIVE SCENES On the few days that call for it, the scene hangs lanterns or lights — Chinese, Japanese or Western. The weather itself is untouched. WARNINGS, AND HONESTY ABOUT WHERE THEY CAME FROM Where a national weather service publishes warnings the app reads them and names the issuer — the US National Weather Service, or MeteoAlarm for Europe. Everywhere else it derives its own advisories from the forecast and labels them as derived, rather than dressing them up as official. SEVEN WIDGETS ON THE HOME SCREEN Tonight's sky, with the Moon at its true phase and the planets that are up. Today's conditions. The five-day outlook three ways — icons, floating high and low bars on one scale, and rainfall beside the chance of rain. What to wear. And the scene itself, photographed from the app while it is drawing it. YOURS, IN YOUR UNITS Temperature, wind, pressure and distance each switch independently, or follow your region. English, Français, 繁體中文, 简体中文 and 日本語, system or hand-picked. PRIVATE BY DEFAULT No account. No analytics. No advertising. The forecast comes from Apple's own WeatherKit, and searching for a place goes through Apple's frameworks — so the only thing that leaves your phone is where you want the weather for. FREE AND PRO Free keeps one saved place plus wherever you are, with the full conditions panel, the hourly and five-day forecasts, and warnings and advisories. Pro adds unlimited places, the seven widgets, the other fifteen landscapes, and the timeline to scrub hour by hour — today and the days on either side of it. Subscribe, or buy it once and keep it. NOT A WARNING SERVICE This is a weather app for looking at, not a safety system. For decisions that matter, use your national weather service and follow your civil authorities.
