Soluvit 2.0
The live UV index, a burn-limit countdown that watches the clock for you, and an honest vitamin D estimate. On every Apple screen you own.
Live burn limit
Skin type, clothing, SPF and the live UV — distilled into one honest number that ticks while you tan. When it reaches zero, you'll know.
10-day forecast
An hourly UV curve for today, and ten days ahead — so the run, the beach day, and the school pickup can all dodge the worst of it.
A two-column dashboard with today’s UV curve built right in. Not a stretched phone app — a layout made for the canvas.
Also available on Apple Silicon Macs and Apple Vision Pro.
Apple Watch
Fully standalone. The watch finds the UV, runs the session, and taps your wrist as you approach your burn limit.
Haptic taps at 50%, 75%, 90% — and an insistent one at the limit.
Live UV on your watch face and in the Smart Stack.
Start and stop sessions without touching the screen.
Glanceable widgets for the Home Screen and Lock Screen.
The sun fills your daily vitamin D goal; one tap logs the supplement that covers the rest.
History and settings sync across your devices through your own iCloud — no one else's.
European air quality index, right beside the UV.
Add a past session and Soluvit reconstructs the UV for that exact hour and place.
Time in daylight and vitamin D land in Apple Health, next to everything else.
No accounts. No ads. No data brokers. Your location is used on-device to fetch the UV where you stand, and your history lives in your own iCloud and Apple Health. Read the privacy policy.
Burn-limit and vitamin D calculations are based on WHO UV index bands and published research on minimal erythema dose and cutaneous vitamin D synthesis. Soluvit provides wellness estimates, not medical advice.
