About this app
Enjoy the sun. Just not too much of it.
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 personal burn time for right now, for any hour ahead, and for the days to come.
Log your sunscreen and that time stretches while the SPF holds. The reminder to reapply follows the real UV and your skin, not a fixed two-hour timer.
The sun isn’t the enemy. SunMate estimates the vitamin D minutes your skin type needs, and keeps a running sun budget, so you can see how much UV your skin has actually taken and head for shade in good time.
WHAT YOU GET
☀️ Live UV index and day 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, and the reapply reminder does the rest.
⛱️ Daily sun budget. A ring that fills the longer you stay out, and speaks up before it’s full.
💊 Vitamin D estimate. Minutes of sun for a daily dose, by skin type.
📅 Peak UV for the next three days, each day curve one tap away.
🔔 UV alerts and a morning briefing. Know before the sun turns harsh.
👨👩👧 Separate reapply reminders for everyone in the household.
📱 Widgets you design. Home and lock screen, your colors, your places.
🌍 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 UV 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, the van Heuklon ozone climatology and the Madronich 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. A screen inside the app lays out each model, its sources, 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.
