SunDose+

See how much vitamin D your skin could be making from sunlight right now, and how long is safe before you cover up. SunDose combines live UV and cloud forecasts for your exact location with your skin type, exposed skin and age. The result is a clear, personal estimate of your vitamin D window and a sensible limit for time in the sun. YOUR DAILY SUNLIGHT CHART A single chart shows UVB, UVA and infrared across the day where you are. Sunrise and sunset markers, a live "now" reading and a highlighted best vitamin D window make it easy to plan time outdoors. SKY CONDITIONS THAT MATTER Choose Clear, Mild, Moderate or Heavy cloud, or use hourly forecast detail. The curve reshapes instantly, so your estimates reflect the sky above you rather than a generic average. GUIDED SUN SESSIONS Start a session and SunDose runs a safe-limit timer alongside a running vitamin D estimate tuned to your Fitzpatrick skin type. Every session is logged so you can see your patterns over time. CAMERA LIGHT METER Point your camera at the light around you to measure lux and get an estimate of UV strength. Useful for comparing shade, windows and open sky. PERSONAL PROFILE A short Fitzpatrick skin-type quiz, exposed-skin presets, your age and a daily vitamin D goal help tailor every estimate to you. SLEEP CHECK-INS Record bedtime, wake time and time awake during the night. Weekly averages and a shareable sleep card help you notice how daylight and rest fit together. REPORTS FOR YOUR PRACTITIONER Export a clean PDF Sun Exposure & Sleep Report with your sessions and sleep data, ready to share at your next appointment.
