Bask - Vitamin D Sun Tracker

Sun Timer, UV Index & Forecast

Free · In‑App Purchases

Vitamin D is the easiest deficiency to fix, but the hardest to track. Bask estimates the IU you get from every sun session and supplement, so you can stop guessing and start hitting your goal. Other apps just count pills. Bask reads the sky, live UV, weather, your skin, and what you're wearing to tell you the best time to step outside and exactly how long to stay. SUN SESSIONS, DONE SAFELY - Real-time IU estimates from live UV + weather - Built-in timer with time-to-sunburn guidance so you never overdo it - Live Activities keep your session on the Lock Screen (iOS 16.1+) FIND YOUR BEST SUN WINDOWS - 48-hour forecast of your optimal exposure times - Get notified right before your best window opens SUPPLEMENTS + COFACTORS - Quick-log common vitamin D doses in a tap - Track magnesium & vitamin K2 with bite-size education cards HISTORY, STREAKS & INSIGHTS - A clean timeline of every session, supplement, and note - 7 / 30 / 90-day trends to watch your levels climb PRIVATE BY DESIGN - Your data stays on your device - Optional Apple Health integration - Optional opt-in leaderboard Bask is for educational and wellness tracking only and does not provide medical advice. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
