### 5/5 — Everything i could ever ask for!!

*2026-03-04, version 2.4.8*

This app is awesome!!

### 5/5 — Extremely Promising!

*2025-11-13*

I live in New England and making sure I catch the sun while buried in work has been very difficult. I'm loving this app so far even thought it has been only very few days I've been on it! Hope to see it succeed !

**Developer response:** Thank you for the kind words! Great to hear its helping you catch the sun!

### 5/5 — Awesome app

*2025-10-09, version 2.4.5*

Great app for those looking to for important Vit. D input.

### 5/5 — Very Helpful

*2025-05-17, version 2.3.8*

Awesome app for keeping track of my sunlight intake, the reminders are very helpful!

### 2/5 — Ok app

*2025-03-19, version 2.3.6*

Ok app. Subscription gets pretty expensive after the free trial. Good that you can see the sunlight lux using the app. However it supposedly gives you a recommendation for morning sunlight duration but it’s always 6 mins when it’s sunny and 21 mins when it’s overcast. So just save your money and use those timeframes without an app.

### 5/5 — Absolutely Love It

*2025-01-29, version 2.1.8*

Great app very interesting

### 5/5 — Excellent App!

*2025-01-28, version 2.1.8*

Forces me to get outside and get my sunlight! Love it. Love the design as well.

### 5/5 — Love this app!

*2025-01-12, version 2.1.1*

Such an amazing app!

### 4/5 — Great design but overpriced

*2025-01-02*

I like the modern design very much, but the app has far too few features to justify the price.

I find a big disadvantage that, for example, over a period of several minutes only the lux value from the start is recorded and the "development" cannot be taken into account. Especially in the evening hours towards the sunset I notice it.
I also couldn't find out whether the app can take into account whether you are only in the sun with your face, in a T-shirt or topless. Which accordingly exposes more or less skin to solar radiation (for vitamin D production).

The functionality to share the data with, for example, Apple Health in order to be able to provide the values in other apps is also missing.

UPDATE 02.01.25:
Because they included new features got, I will give the App now 4 instead of 2 stars. „Only“ 4 because I still think that it is too expensive.

**Developer response:** Thank you for the feedback! We’re continuing to add new features each week, and will make the experience better over time.

We’ve now added support for Apple Health, so activities will be synced. 

For vitamin D production we’ve added a slider/picker to identify if the user is fully clothed and limited skin visibility. This will reflect the IU captured from the sun. 

Capturing Lux overtime is a cool idea. We’ll figure out how to implement this in an effective way. 

Thank you for helping us make the best sun app for health ☀️

### 3/5 — Solid idea / hidden cost

*2024-12-20*

There was nothing obvious on the website or App Store listing about the cost. I’m not saying there shouldn’t be a cost, but tell me up front. I dislike when I see the cost only once I give my info. I won’t give a car dealership all of my info (and time) and THEN ask how much the vehicle costs. I like the idea (many people are D deficient) and the app looks really good. Three stars.

**Developer response:** Thanks for the thoughtful feedback! We really appreciate you taking the time to share your experience. We understand how important transparency is, and we’ll work on making pricing information more visible upfront in the App Store listing and onboarding process.

We collect basic info to personalize the experience for you, and the premium option is entirely optional—you can always enjoy the free features without subscribing. We’re constantly adding value to make the premium plan worthwhile, but we’ll take your comments to heart to improve.

Thanks again for your support and for helping us make SunSeek better! 🙏☀️
