Accurate UV, hour by hour
Sunkind pulls real-time UV for your exact location from Apple WeatherKit, with an hourly curve and a 10-day forecast — so you can see UV climb and fall through the day, not just a single daily figure.
UV that means something for your skin
A UV index of 6 isn't "good" or "bad" on its own — it depends on your skin. Sunkind reads the UV against your Fitzpatrick type and tells you the SPF to wear and how long you can safely stay out.
Alerts that respect your day
Get one gentle morning note on good-window days, plus a heads-up when UV is about to climb past your safe ceiling — useful, never spammy.
