I like the app, but there are updates every other day and many of them keep breaking the core functionality (like starting a sun session). My guess is the Dev isn't a true developer but is instead vibe coding, or maybe they only test on iOS. Anyway when it works it's a 5-star app. The one thing that has never worked are the notification settings, I've tried customizing them but still get every notification anyway.

Got this app after getting blood work done and finding out I was deficient in vitamin D, about two months ago. I tracked all my sun sessions and supplements and food intake up until now. Just a few days ago I got blood work done again, and I am no longer deficient! The app was also exactly right in its estimation of my vitamin D level. The only complaint I have is that once or twice the estimated level would jump way, way up randomly. Also inputting my lab results threw the estimated level way off

I've been using this app for I think almost 10 years, BUT why with the newest update, did you make it impossible to put in the true previous sun session time length?? Instead it's maxed at 2h? I preferred the previous older looking version, it had more functionalities

This used to be a great app. I used it for over two years with no problems. During that time, the tracked numbers would be within a couple digits of my vitamin D lab test results. That was pretty amazing. Since it was updated, this app no longer functions properly except as a supplement tracker. You can't track a live sun session. Adding prior sun sessions don't accurately reflect the correct IUs obtained. Inputted lab results, erroneously throw off the tracker.

No longer able to initiate a sun session. Ever since last app update, I can only log sun sessions by entering them in history as past sun sessions. Lastest version of Android.

Used to be good before recent update but now the app is useless, avoid.
