Description
Sunlight isn’t the problem. The dose is.
SunMate turns the live UV index into the one thing you actually want to know: how long your skin can stay out today. Pick your skin type once, and you get a burn time for right now and for any hour you’re planning around. Sun protection without writing off the afternoon.
Log your sunscreen and that time stretches while the SPF holds. The reapply reminder is timed off the UV and your skin, so it doesn’t just count down two hours and beep.
Sun is also how your body makes vitamin D, and SunMate works out roughly how much your skin type needs for it. A running sun budget shows how much UV your skin has already taken, so you can get into the shade before it’s too much.
WHAT YOU GET
☀️ Live UV index and the day’s curve. Hour by hour, clouds included. ⏱️ Your burn time for right now, in the sun or in the shade. 🧴 Tap once when you put sunscreen on, log the SPF, and the reapply reminder sets itself. ⛱️ A sun budget ring that fills the longer you stay out, and speaks up when it’s getting close. 💊 A vitamin D estimate that only counts while the sun is high enough to make any. 📅 The 3-day outlook: a UV forecast with each day’s peak, plus alerts and a morning briefing so a harsh afternoon isn’t a surprise. 👪 Separate reapply reminders for everyone in the household. 📱 Widgets you design for the home and lock screen, in your colors. Saved places keep their own UV and their own time zone.
IT SHOWS ITS WORK
No phone can measure UV, so every number here is computed, and SunMate says what from. The index is an hourly NOAA-sourced forecast from currentuvindex.com, with the forecast cloud cover already in it. The cloudless reference is worked out on your phone, from the NOAA solar equations, van Heuklon’s ozone climatology and Madronich’s clear-sky relation. Burn time, the sun budget and the vitamin D estimate are arithmetic on the CIE erythema weighting against your skin type’s MED. One screen in the app lays out every model and where it stops being reliable.
No account, no ads, no tracking. The UV index, your burn time, the sunscreen log, vitamin D and today’s sun budget are free. SunMate Pro is a one-time purchase, not a subscription, and adds the 3-day outlook, UV alerts, the morning briefing, household profiles, saved places, sun history and extra widgets.
Your skin type, places and sunscreen log stay on your phone.
UV values are model estimates. Burn times and the sun budget are rough personal guidance, not medical advice. When in doubt, get in the shade.
Recent changes: v1.0.2 - A logged SPF is now discounted before it reaches the maths, so SPF 50 no longer flattens burn time and the sun budget - Sun time logged just after a sunscreen entry stays on today - Data & method covers the UV-A gap, the Fitzpatrick bias on darker skin, and what UV 400 on sunglasses means - Rate SunMate from Settings > About - Reworded copy across the app and the store listing
