### 1/5 — Gets everything wrong

*2026-07-05*

I put information like we when and how often I apply sunscreen but it immediately deletes. The apply sunscreen button should be in conjunction with the daily or multiple times a day application. No edit feature if I've already applied sunscreen and forgot to log. Not tracking sun exposure or uv levels that well for literally being what the device is for. It misses a lot of sun exposure and always says the uv index is lower that every other weather app says by 2-3 levels. Can't click on the charts to get more information.

### 4/5 — Great app maybe some room to grow

*2026-07-10*

I really like this app! It has been a great tool for helping me monitor my UV exposure and stay more aware of my time in the sun.

One feature I'd love to see in a future update is the ability to indicate when I'm wearing UV-protective clothing or using an umbrella, so the app could factor that into my overall UV exposure.

Overall, I love it and can't wait to see how the app continues to improve!

### 5/5 — Awesome!

*2026-07-10*

Very informative to see real time accumulation of UVA (aging) UVB (burn) and Vitamin D exposure daily versus guessing on a UV index forecast. Love it!

### 5/5 — Best invention!

*2026-07-10*

My favorite feature is the vitamin D level tracking- I love that it tracks how much I am getting daily ensuring I get enough every day. Also, the aging score is so motivating — being able to own how long and when to get out of the sun is a game changer. Simple, clear, and it’s changed how I think about a daily habit I used to ignore completely. Highly recommend.

### 5/5 — Very helpful

*2026-07-10*

I’ve been using the gem for about a week and have been very interested in what I’d learn. Long story short I was getting a ton of sun I didn’t realize.
