## What is Sun Exposure?

Sun Exposure is your smart companion for outdoor living. Track your sun exposure, estimate Vitamin D production, monitor burn time, time your morning light, and get personalized guidance — all designed to help you enjoy sunlight safely, whether your goal is staying protected, boosting Vitamin D, building a healthy tan, or starting your day with morning light.

See how much sunlight you've had today with a quick glance. Start a Sun Session right from your iPhone to record your time in daylight — no Apple Watch required. Or pair with your Apple Watch for automatic, all-day sun tracking with real-time insights and recommendations so you can get the benefits of sunlight without the burn.

FREE FEATURES
- Daily Sun Tracking - See how much time you've spent in the sun today at a glance.
- Sun Sessions - Record your sun exposure directly from your iPhone. Your Time in Daylight is saved to Apple Health automatically.
- Smart Sun Guidance - Get personalized recommendations on when to get more rays, apply sunscreen, or move to the shade.
- Widgets and Complications - Access your sun stats from your home screen or Apple Watch face.
- Exposure Notifications - Get alerts when you've reached your daily sun limit.

PRO FEATURES
- First Light (New) - See what time you first get daylight each day, and how it compares to your wake time and local sunrise. Getting outdoor light soon after waking is widely recommended to help set your circadian rhythm for better energy, mood, and sleep.
- Automatic Vitamin D Logging - Your estimated Vitamin D intake is calculated and saved to Apple Health throughout the day, automatically. No need to start a session.
- Burn Time Alert - Get notified when your safe sun time reaches zero based on your exposure and the current UV Index.
- Vitamin D Estimate - See how much Vitamin D your body is producing based on your sun data, the UV Index, and your skin type.
- Burn Time - Know exactly how much safe time you have left in the sun right now, based on today's exposure, UV forecast, and your skin type.
- Sun Session Vitamin D Tracking - With location enabled, Sun Sessions calculate and save your Vitamin D production to Apple Health.
- Custom Exposure Goals - Tailor your sun time for Vitamin D, safe tanning, or balanced wellness.
- Forecasts - UV Index and weather forecasts help you plan the best times for outdoor activity.
- Reminder Alerts - Stay balanced with gentle nudges throughout the day.
- Sunrise and Sunset Tracking - Plan your outdoor sessions around daylight hours.

WHY SUN EXPOSURE?
- Sunlight is essential for Vitamin D, mood, sleep, and overall well-being, but overexposure puts your skin at risk. Sun Exposure helps you find the right balance — enough sun for health and glow, without crossing into damage.
- Track sun exposure with or without an Apple Watch. Automatic all-day sun tracking with Apple Watch requires watchOS 10 or later. Sun Sessions work on iPhone for on-demand tracking anytime.
- Privacy first - no personal data leaves your device unless you choose to share it.

Disclaimer: Consult your doctor to determine the right amount of sun exposure for you. Always use sunscreen, hats, and shade as needed.

### 5/5 — Keeping my hot husband hot

*2025-10-17*

My husband won’t listen to me when I remind him to put on sunscreen/stay out of the sun, but he will listen to an app. Thanks for making this app so he will retain his youthful skin!

**Developer response:** Thanks for the review! I'm sure your husband is trying his best!

### 1/5 — Seems to have quit working

*2025-05-24*

Worked for about a week but is no longer working. Reports 0 exposure daily now.  Time to uninstall. Wasnt worth the $11.99.

**Developer response:** Hi there, I'm disappointed to hear it isn't working for you. We've shipped out a number of improvements since then that should address any 0-exposure issues. Please give it a try and if it's still not working email us at hello@sunexpsosure.app to we can fix it!

### 1/5 — Worthless

*2024-06-28*

Another worthless app.  It clearly says you can pair it with a compatible Apple Watch, but neither recognizes your watch, nor tells you how to connect the app to your watch.

**Developer response:** Hi there, there are no special connection steps required to connect your Apple Watch beyond granting the Health permissions. Please reach out at hello@sunexposure.app and we can help get you setup!

### 5/5 — Such a great app!

*2024-06-15*

The only thing that I think could make this app better is UV exposure information from weather.

**Developer response:** Hi! Thanks for the review! We just added UV index forecast to our latest release 1.3 and plan to add more features along this line in the future.

### 3/5 — Exposure while inside?

*2024-06-09*

Was not wearing my watch today and it was charging in my office. However, app told me that I got sun exposure. Hmmm.

**Developer response:** Hi there, thanks for the review! We are using the Apple Watch's default sun exposure tracking, but it is curious to see this behavior 🤔

### 1/5 — Doesn’t work

*2024-06-09*

I tried it oveer several sunny days, bare armed on my Apple Watch. Never worked. Not even once.

**Developer response:** Hi there, I'm disappointed to hear about the app not working. Can you please check that Apple Health permissions were granted correctly and you watch is running watchOS 10 or later? If you email us at hello@sunexposure.app we'd be happy to help!

### 2/5 — I’d love see the app evolve

*2024-06-08*

Exactly as advertised unfortunately it’s not a uv tracker as well or vitamin D tracker. Morning sun light and evening are most likely to be healing rather then damaging due to different wave lengths.

**Developer response:** Thanks for the review!

### 5/5 — Keeping my hot husband hot

*2024-04-17*

My husband won’t listen to me when I remind him to put on sunscreen/stay out of the sun, but he will listen to an app. Thanks for making this app so he will retain his youthful skin!

**Developer response:** Thanks for the review! I'm sure your husband is trying his best!

### 5/5 — What Apple Needs!

*2024-04-06*

Simple to use, very clean and nice UI, works as should!

**Developer response:** Thanks for the review! May the weather be in your favor 🌞

### 1/5 — Great idea but...

*2023-09-22*

I have downloaded this app twice now. I have iOS 17 running on my iPhone SE 2 and Apple Watch SE 2 running AW OS 10.1  In both cases the devices are compatible with the app but I simply cannot get it to work.  I have tried on two consecutive days spent at the swimming pool but it continues to display zero time spent in sunlight.

**Developer response:** Hello - I'm disappointed to hear about the issue. It sounds like your Apple Health permissions may not be granted correctly. Please reach out to hello@sunexposure.app and we can take a look!
