The idea behind this application is that it will help you track and manage your Vitamin D. This new version integrates with the Apple Health app to make seamless data exchange possible in the following ways: * on setup, profile information is fetched from the Health App if the user allows it * the user's weight (a factor in D generation) is fetched on an ongoing basis, making it unnecessary to update it * the app will write vitamin D doses, including session information into the Health app You setup basic information one time, like your height and weight and skin type and then any time you are outside, during the prescribed hours (and parts of the year), you can have it compute the amount of D you are getting in a stopwatch interface. It will also track how long you can stay out and warn you when the time is up. The application will notify you with the next opportunity to generate vitamin D. Each day, you can see forecasts based on your location, and you can also see the solar position, your generated vitamin D vs. target etc. In the Pro version, you can see your exposures's history and you will be able to schedule future events for next exposures.

It’s easy and useful. Seems accurate in that my blood test line up with what the app predicts. ### 5/5 — Sun Lover *2026-08-11, version 100.8.29* 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! ### 1/5 — Great to barely ok *2026-08-11, version 100.8.28* 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! ### 2/5 — Is Ok, but has lots of issues *2026-08-09, version 100.8.28* 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. ### 1/5 — Opens to a black screen *2026-08-01, version 100.8.23* 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. ### 4/5 — Black Screen *2026-08-01, version 100.8.23* This app used to be good but now all I get is a black screen when I open the app, on my iPhone 15 Pro with the latest iOS 26. It used to work on this phone. You used to get a brief glimpse of the correct app page, but since the latest update you don’t even get that anymore. This latest update has not fixed the problem. When is this going to be fixed properly. ### 5/5 — I want to give 5 starts but *2026-07-29, version 100.8.19* I want to give 5 starts but I think the app is fine tuning its new update. It is EPIC. I loved this app before and now it is infinitely better. The free version is all you need - excellent app. ### 1/5 — Used to be 5 stars *2026-07-27, version 100.8.18* I loved the previous version of this app. It worked perfectly tracking my sun sessions and I would have rated it 5 stars. There are now so many bugs. Today it tracked 1 minute of my entire session. It also tells me after 7 minutes or so that my sun session is over when the old version used to say I had 20 minutes per side during the same time of day. It’s completely unusable at this point. ### 1/5 — still broken *2026-07-26, version 100.8.17* App still shows 0 IU for exposure after session if you have your phone screen locked. Please bring back the old version from years ago and call it dminder classic or something ### 3/5 — Loved the old version *2026-07-25, version 100.8.17* I appreciate this is a free app and helpful to track sun. The old version was simpler to use and the new one has SO many bugs. It constantly changes my session times to hardly anything, and it won’t let me edit the start time to fix it (changing just the ending affects the uv index sometimes). Past sessions mysteriously deleted. If no bugs and easy to edit, would be perfect! ## Frequently asked questions about D Minder Pro ### What does D Minder Pro do?
