About
Vitamin D Tracker is a sun coach for people who want a gradual tan, more vitamin D, and a plan that respects their skin. It uses live UV at your location, your skin type, and how you actually spend time outside.
WHAT YOU CAN DO
Personal sun plan
Answer a few questions about your skin, clothing, and routine. Vitamin D Tracker builds a week of sessions with the best windows, a safe time limit, and rest days when UV is too low or you need to recover.
Track a session
Start tracking when you head outside. Pause, resume, and save minutes, estimated vitamin D, and the UV you were under. Log a session by hand if you forgot to start the timer.
See why today
Home shows today's UV, your next window, and whether conditions are good enough to go out. The Plan tab looks 10 days ahead so you can pick the right afternoon, not just the next hour.
Stay on it without opening the app
Widgets for the next session and for tracking. Reminders before your best window.
Progress you can see
Minutes in the sun, estimated vitamin D over time, and your tan journey in one place.
DESIGNED FOR PLANNING, NOT MEDICINE
Vitamin D Tracker uses weather forecasts and the profile you give it. It is not a medical device, does not measure your vitamin D blood level, and does not diagnose or treat any condition. Talk to a clinician about skin or vitamin D concerns.
VITAMIN D TRACKER PRO
The free plan covers today's sun plan. Vitamin D Tracker Pro unlocks an enhanced experience: adaptive weeks that move with the weather, full history, travel planning, and deeper dose insights.
