About this app
SunDTracker – Your Personal Sun Exposure Companion
Know how long you have been in the sun, and how much vitamin D you gained. SunDTracker combines your location, the live UV index and your personal skin type into a clear picture of every sun session.
KEY FEATURES
• Personal sun tracking based on skin type (Fitzpatrick I–VI), age and weight
• Live UV index and solar position for your location
• Session timer with start/stop and background updates
• Sunburn warnings before your skin reaches its limit
• Multiple profiles – ideal for the whole family
• PIN protection for individual profiles
• UV forecast for planning your day
• History, statistics and daily logs
• Supplement logging in IU or μg
• Data export as CSV or PDF over any date range
SMART CALCULATION
SunDTracker estimates vitamin D synthesis from:
• Live UV index and cloud cover
• Solar elevation for your position and time of day
• Skin type on the Fitzpatrick scale
• Exposed body surface, clothing and sunscreen
• Altitude and weather conditions
PRIVACY FIRST
• All data stays on your device – no cloud sync
• Encrypted local database
• Location is used only for UV values and is never stored on a server
• Full control: export or delete your data at any time
FREE AND PREMIUM
The free version is ad-supported and includes three weather updates per day; the values retrieved last stay available all day. Premium removes all ads and allows unlimited weather updates – the first month is free, then it continues as a monthly or yearly subscription (price shown in the app).
PERFECT FOR
• Families sharing one device
• Outdoor workers and athletes
• Beach, pool and garden
• Anyone who wants vitamin D without sunburn
