Good concept
Good concept, flawed execution. To begin the inability to retroactively add SPF is beyond frustrating - life gets busy, it should be an easy thing to go back and add at the end of your day.
Notifications when you’re reaching thresholds would also be extremely helpful.

Dear Customer, The functionality to apply SPF and clothing retroactively is scheduled for the next big release (ETA in September). Notifications for thresholds are already in place, however, if you are on iOS 26.5.2, they won't be coming until you hard restart your phone. Hope it helps. Sincerely yours, The90 Customer Support Team
Love this product
It works well
Awesome!
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!
Great app maybe some room to grow
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!

Response from developer
Dear User, thanks a lot for your feedback and suggestions. We have included UV-protective clothing to our product development pipeline and this will be released in one of the future versions of the app. Sincerely yours, The90 Customer Support Team.
Best invention!
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.

Very helpful
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.
Gets everything wrong
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.
