Comments on Vitamin D Tracker & UV Index for Android

★★★★★ Coenie · Aug 16, 2024

Would like to see solar elevation or altitude without notification or login. Also, coarse location only necessary.

★★★★★ Erin Lehto · Oct 1, 2025

So far the best free vitamin D and uv tracking app! Allows you to put in your sun type which changes how long it takes to get a burn and how much vit d your getting, which is a step up from minder.

★☆☆☆☆ Bob Rose · Mar 26, 2025

Uninstalled almost immediately- won't work unless logged in, not obvious how to do this-then immediately failed 'finding location data' (I had enabled this already in my phone settings), no options in settings to fix this, in fact barely any options/functions available in this app at all

★☆☆☆☆ Samuel Colosimo · May 20, 2025

I can't sign in and there is no forgotten password option. I know I haven't forgotten my password because it's a password ive used for a long time. But the amount of times you have to do that on other bugged services to get in... ps. I emailed you, just saw it after my review since I didn't know if there was another way to contact you. I will change the review once this is sorted in a reasonable amount of time.

★★☆☆☆ Thérèse Bonin · Dec 10, 2024

Hmmm. The interface is clean and easy to use, but the app sends me notice of solar noon as the best time to make vitamin D, as if it were possible to get vitamin D from the sun on a December day in Pittsburgh. It’s not and won’t be for many more weeks.
