What's New in D Minder Pro

100.8.28

August 8, 2026

Pocket sessions now count. If you start a sun session and put your phone away, iOS suspends the app — and previous versions credited you almost nothing for that time. Now the time your phone spends in your pocket is credited at the rate the app measured, both for vitamin D and for burn tracking, for up to two hours. A session paused for more than 30 minutes is considered finished; a session that crosses its planned target while your phone is away completes itself with full credit. Also in this release: a bug that could freeze the vitamin D calculation at zero after a brief location interruption is fixed; purging the iCloud sync zone from Settings now recreates it cleanly; Clear All Data now also removes records from iCloud; a new Settings button clears the on-device backup; and editing a supplement schedule's end date now removes doses past the new date.

Dead app

Loved this app but recent update makes my app go black. Now I can’t use it. No matter how many times I close out it won’t open without a black screen.

Please fix this. I want to use the app and then I can change review to 5 stars cause I liked it a lot.

Black screen

I’ve had this problem for weeks now

Glad to see I can finally open the Ap

So far so good…

Bit scared to do updates!

I can’t see. Spot to add a good dose with the new update?? Lamp, supplement and sun yes…
Ok- I found “food dose” .. it’s buried under history- not on front page like it used to be… also… when you type in a food - it’s all manual, there’s no search feature like in the old Ap- and even if I choose from common food list (eg egg YOLK).. I can only select one egg yolk.. hard to see how to make it multiple., except for manually guessing the IU dose,

Also uv lamps/beds are illegal in Australia… probs best not to promote that option…

Back to being completely awesome!!!

This app underwent some BIG changes over the last few months. It’s great again! Thanks so much for the work you guys are doing. This app has been incredibly helpful for me to get D naturally. I have a gene mutation that has made it impossible for me to supplement with pills to get vitamin D. I need to get D safely and this app is helping me to do that. 🙏🏼🩷

Ok

But why won’t it update ? I’m permanently stuck on Imperial
