About
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!

What's new
Version 2.2: Native Watch Menu,SPF Timer Mode,Sunset Catcher Alert,1-Click AUTO Reset,Sunset Alert.
Native Watch Menu: Long-press the physical MENU button to access the brand-new on-device control panel.
SPF Timer Mode: Applying sunscreen? Set an SPF timer (30m to 120m). The bio-engine instantly drops your Vitamin D generation to exactly 3% to reflect real-world physical UV blocking. The watch will vibrate when it's time to reapply.
Sunset Catcher Alert: A new smart background notification. If enabled, the watch will remind you to catch some sun exactly 3 hours before sunset — but only if your daily score is still in the CRITICAL zone.
1-Click AUTO Reset: Quickly clear all manual UV and temperature overrides with one click to restore live GPS weather tracking.
On-Watch Quick Settings: Control core features directly from your wrist (no phone required):
Wrist Detect: Uses the heart rate sensor to automatically pause Vitamin D generation when you take the watch off.
Danger Alerts: Enables background warnings if you absorb 4x your daily limit (High Sunburn Risk).
Sunset Alert: Toggles the new 3-hour pre-sunset reminder.
Vibrations: Turns haptic feedback ON/OFF for status changes and timer expirations.
