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. Sunshine 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), Sunshine 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. Sunshine removes that friction entirely. VITAMIN D ESTIMATION Based on current UV index, your skin type (Fitzpatrick scale), and outdoor time, Sunshine 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. SUPPLEMENT TRACKING Sunlight isn't the only source. Log vitamin D, K2, magnesium and omega-3 with one tap, and they're added to what the sun gave you for one daily total — synced both ways with the Health app. SAFE SUN TIMER Sunshine 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. Sunshine 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 Sunshine 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. Sunshine 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. PREMIUM (OPTIONAL) Unlock advanced insights, additional widget styles, and premium features. Weekly ($0.99), yearly ($5.99), or lifetime ($9.99).

Everything should feel a little steadier and smoother now. Have a suggestion? We'd love to hear it. ### 6.1 — 2026-08-01 Your vitamin D doesn't only come from the sun. You can now log supplements — vitamin D, K2, magnesium, omega-3 — with one tap a day.

Everything syncs both ways with the Health app, and vitamin D logged in other apps counts too. New insights show your last 30 days, how much came from sun versus supplements, and which one you keep forgetting. ### 3.1 — 2026-06-27 Bug fix ### 1.22 — 2026-06-03 Bug fix ### 1.21 — 2026-05-18 Bug fix ## Apps similar to Sunshine | App | Rating | Price | Category | | --- | --- | --- | --- | | [一息 - 极简冥想与正念呼吸](https://appshunter.io/ios/app/id6744656485) | — | $1.99 | Health & Fitness | | [My Water Reminder](https://appshunter.io/ios/app/my-water-reminder/id6752773542) | 5.0 (1) | Free | Health & Fitness | | [Pulse Vitals: Health Tracker](https://appshunter.io/ios/app/pulse-vitals-health-tracker/id6772466715) | — | Free | Health & Fitness | | [Walk Under the Sun](https://appshunter.io/ios/app/walk-under-the-sun/id6760441587) | — | Free | Health & Fitness | | [Vitamin D Sun Tracker - Bask](https://appshunter.io/ios/app/vitamin-d-sun-tracker-bask/id6758405235) | 4.9 (9) | Free | Health & Fitness | | [UV Index: Sun & Tan Tracker](https://appshunter.io/ios/app/uv-index-sun-and-tan-tracker/id6767737330) | — | Free | Health & Fitness | ## More apps by 帅 陈 - [LiveMarquee: Celebration&Panel](https://appshunter.io/ios/app/livemarquee-celebration-and-panel/id6748575779) - [BucketPal: Life Calendar](https://appshunter.io/ios/app/bucketpal-life-calendar/id6752753272) - [3ThingsPal: ADHD Focus List](https://appshunter.io/ios/app/3thingspal-adhd-focus-list/id6754563220) - [DishPal: AI Grocery List](https://appshunter.io/ios/app/dishpal-ai-grocery-list/id6755170439) - [SWOTPal - AI Business Planning](https://appshunter.io/ios/app/swotpal-ai-business-planning/id6756004194) All apps by 帅 陈: https://appshunter.io/developer/1655624601 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
