PeakUV warns you before the UV index climbs — not after you're already burning. Most UV apps show one flat number for your whole town and only alert you once the threshold is already crossed. PeakUV is built differently. PREDICTIVE ALERTS Alerts are computed from the forecast with lead time, so you hear "UV hits 8 around 13:00" before it happens — time to find shade, not a notification after the damage is done. ALTITUDE-AWARE UV rises with elevation, and the published forecast is for the weather model's grid height, not where you're standing. PeakUV corrects to your actual altitude and tells you so — essential in mountain terrain like the Pyrenees and the Alps, where you can climb 1000 m in a single day. AT A GLANCE • Home-screen and lock-screen widgets • Apple Watch app and complication • A clear hourly curve with plain-language severity bands, from Low to Extreme HONEST BY DESIGN This is forecast data, not a measurement from your phone — and we say so plainly. We show "roughly 9 up high," never false precision. Snow glare can add a lot of UV but can't be read from the forecast, so we don't guess at it. We'd rather be honest than fake it. PRIVATE No account, no tracking, no ads. Your location is used only to compute your forecast. You can delete your data any time from Settings. The UV warnings are always free. Available in English, Català, Español, Français, Română, Deutsch, Italiano, Português, 日本語 and 한국어.

Verdict
The clearest difference is device support: PeakUV at 4 against UV予報's 1. PeakUV also leads on iOS requirement (15.0 vs 17.6). On price, ads and in-app purchases there is nothing between them.
