SunshinePal: Sun & UV Tracker
Daily Sun Exposure & Vitamin D
Free · In‑App Purchases · Designed for iPhone
April sun is warmer, longer, brighter. Set your daily sunshine goal on Apple Watch, build a streak, and feel the difference more light makes.
Most people don't realize they're not getting enough sunlight until something goes wrong.
Maybe it's the fatigue that coffee can't fix. Maybe it's a blood test showing low vitamin D. Maybe it's winter blues that hit harder each year. Maybe your sleep is terrible and you read that morning sunlight resets your circadian rhythm — but you have no idea if you're getting enough.
The problem isn't knowledge. It's that nobody tracks it. You track steps, heart rate, sleep, calories — but not the one thing that affects all of them: how much natural light you actually get.
SunshinePal fixes this by making sun tracking automatic, passive, and effortless.
AUTOMATIC TRACKING WITH APPLE WATCH
If you wear an Apple Watch (Series 6 or later), SunshinePal uses the built-in ambient light sensor to detect daylight exposure in the background. You don't press start or stop. The watch quietly measures your time in natural light and syncs it through HealthKit.
Manual tracking doesn't work — if you have to remember to open an app every time you step outside, you'll forget in three days. SunshinePal removes that friction entirely.
VITAMIN D ESTIMATION
Based on current UV index, your skin type (Fitzpatrick scale), and outdoor time, SunshinePal estimates how much vitamin D your body is producing. Not a blood test replacement — a daily awareness tool connecting outdoor time to vitamin D levels. On cloudy days or in winter, it helps you understand when supplementation might make sense.
SAFE SUN TIMER
SunshinePal calculates a personalized safe exposure window based on UV index and skin type — how long you can stay in the sun before risking a burn. Especially useful for fair-skinned people, parents managing kids' outdoor time, or anyone in high-UV regions like Australia or tropical climates.
DAILY GOALS AND SCORING
Set a personal daily sunlight target — anywhere from 15 minutes to several hours. SunshinePal gives you a score from 0 to 100 based on how close you get. Over time, you build streaks and unlock achievements through Game Center.
The goal system turns a vague health intention ("I should go outside more") into a concrete, trackable habit.
TRENDS AND INSIGHTS
View sunlight patterns over 7 days or a full month. Weekly rings show consistency. Identify peak outdoor hours. The data reveals patterns you'd never notice — like getting almost no natural light on workdays.
WIDGETS AND REMINDERS
Home Screen and Lock Screen widgets show your daily progress at a glance. A gentle reminder nudges you to step outside if you haven't hit your target — customizable to your preferred time, so it arrives when you can actually act on it.
WHO SUNSHINEPAL IS FOR
Remote workers drained by 3pm without knowing why. People with vitamin D deficiency tracking alongside supplements. Parents ensuring kids get enough outdoor time. Shift workers out of sync with natural light. People managing Seasonal Affective Disorder (SAD). Fitness enthusiasts who know recovery starts with circadian health. Anyone following Andrew Huberman's morning sunlight protocol who wants to track it.
WHY NOT JUST USE OTHER APPS
Most sun and UV apps require manual session start and stop — you'll forget. Popular vitamin D trackers have known issues with location bugs, broken watch apps, and data corruption. Others collect data for advertising. SunshinePal is automatic, reliable, and private.
PRIVACY
All data stays on your device. No cloud upload. No account creation. No data sold to advertisers. No analytics tracking. Your health data is yours — period.
