Stay Healthy & Motivated: Smart Vitamin D Estimator
Gamify your sun exposure! Powered by a realistic biological algorithm based on peer-reviewed clinical research, this widget estimates your Vitamin D synthesis in real-time based on environmental data, sun position, and your personal stats.

Smart Exposure & UV Control
The algorithm dynamically calculates your synthesis based on real-time Garmin Weather data.

Manual UV Override: Ultimate control for situations your watch can't detect!

Indoors/In a Car: Window glass blocks 100% of UVB rays. Set Manual UV to 0.

Beach Mode (Swimwear): Standard modes assume summer clothing. If you are in swimwear, your skin exposure is roughly 3x higher. To compensate, multiply the current UV index by 3 using Manual Mode. If you take the watch off to sunbathe, simply leave the app open on the screen to continue tracking!

Astronomical Safeguards: To maintain realism, manual UV is automatically capped based on precise sunrise and sunset times for your GPS location.

Offline Support: Devices temporarily without Weather API access will operate seamlessly via this Manual UV mode.

Adaptive Temperature Logic
The app dynamically adjusts to the outdoor temperature, estimating how your clothing affects skin exposure:

Cold Mode (below 10°C / 50°F): Optimized for winter gear (jackets, scarves) - minimal skin exposure.

Mild Mode (10°C - 20°C / 50°F - 68°F): Designed for spring/autumn attire (long sleeves, trousers).

Warm Mode (Above 20°C / 68°F): Calculated for summer clothing (t-shirts, shorts) - standard efficiency.
(Tip: Use the UP/DOWN buttons or touch to manually switch modes).

Personalized Precision & Smart Protection

Dynamic Goals: Your UI progress bar and daily status (Critical, Normal, Reserve) adapt to your specific body weight and metabolic burn rate.

Auto-Skin Type: The app automatically determines your skin type based on your GPS latitude for accuracy (manual override available).

Off-Wrist Protection: The background engine detects your heart rate. If the watch is taken off and put in a bag, tracking stops to prevent fake stats.

DANGER Zone Tracking: If your generation exceeds 400% of your metabolic baseline, the UI triggers a red DANGER status. Vitamin D synthesis realistically drops by 80% and eventually stops, preventing fake "infinite" generation and warning you about sunburn risk.

PRO Features: The Reserve Bank & History ($1.99)
Unlock the full potential with the PRO version:

The Vitamin D Bank: You start with a 5,000 IU reserve. Your body constantly "spends" Vitamin D. See your Total Bank (capped at a realistic 50,000 IU) and your Autonomy in Days to know exactly how long your reserves will last without sun!

Live Metabolic Pulse: See your exact synthesis rate directly on the PRO screen (e.g., -1.5 IU/m or +14.2 IU/m).

10-Day Statistics: Track your progress with a synced history chart showing your performance over the last 10 days, with DANGER days automatically highlighted in red.

Background Operation
The widget accurately tracks data in the background.
Important: After updating or rebooting your watch, please open the widget/glance at least once to wake up the background tracking engine!
