Very Useful tool

Keep track of your sun exposure and log your vitamin D production. It’s easy and useful. Seems accurate in that my blood test line up with what the app predicts.

Sun Lover

I’m a practitioner. I recommended to all my clients, super helpful to know how much you’re getting and when to get out of the sun! So you do not burn …Thank you for your app!

Great to barely ok

Not sure why developers have a knack for ruining apps that actually work…but now they’ve done it to this one too. Update Sucks!

Is Ok, but has lots of issues

This app can help you get started and give you general ideas about tracking your vitamin D exposure, but it does come without a lot of issues. I often find that it will miscalculate the IU’s based on my time. I just verify the correct exposure total by a calculator. It often will adjust my end time and I have to go back in and edit it. It seems very glitchy ; for example, my IU exposure might be 89IU’s per minute. After 30 minutes, I should be somewhere around 2.6K. But the app will tell me I have 15IU’s of vitamin D. So in a nutshell, you’re gonna get a basic idea, but you’re definitely not not going to be tracking anything in depth.

Opens to a black screen

This app used to work flawlessly and then many months ago just stopped working because when you open it all you see is a black screen. The latest update claims to fix this - it does not. How all of the recent updates got past QA is beyond me.
