By Astralab Studios, Inc., from Google Play“Live UV index, vitamin D from sun, sunburn timer & best sun window reminders.”
Description by Astralab Studios, Inc. Written by the developer, not by AppBrain. Click to read.
Most sun apps do one thing. This one puts the live UV index and your personal vitamin D estimate in the same place - modern, accurate, and built for daily use.
WHAT YOU GET
- Live UV index for your exact location, with temperature and cloud cover.
- Vitamin D estimates in IU, calculated from the UV index, your skin type, your SPF and how much skin is exposed.
- Your best sun window each day - the hours to catch strong UVB.
- Your sunburn limit for today's UV, with a warning as you get close and when you reach it.
- A sun session timer that keeps counting in the background and saves your session, even if you close the app or end it from the notification.
- Edit a saved session afterwards - date, time, duration, SPF and exposed skin - and the vitamin D estimate updates with it.
- Reminders you control: turn them on or off yourself, so there is no notification spam.
- Streaks and history to see your recent sun and vitamin D over time.
- Write your vitamin D to Google Health Connect, and export everything to CSV whenever you want. Your data stays yours.
- Premium adds a home screen widget with your live UV and this week's vitamin D.
HOW IT WORKS
The app reads the live UV index for your location, factors in your skin type, SPF and exposed skin, then estimates the vitamin D your body can make right now. It shows the best sun window to get it, and the sunburn limit that tells you when to stop.
Whether you want a UV index app, a vitamin D tracker, a sunburn timer or a simple vitamin D reminder, this app brings them together.
Download now to check the UV index, track vitamin D, and time your sun.
