What's New in D Minder Pro

100.8.15

July 19, 2026

This update completes the iCloud profile restore fix from the previous release. Some users who upgraded from an older version of D-Minder had a profile that was missing their name, date of birth, and lab history — the previous update addressed one path this data could come from; this one adds the other, reading it directly from the on-device data your older D-Minder installation left behind. Existing entries you've already corrected yourself are never overwritten.

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

App broken

App doesn’t even start after last updates

Black blank screen

Just opens to a black blank screen. It used to work and was a great app so not sure what’s going on

Black Screen

7-9-26 UPDATE: Still a BLACK SCREEN upon opening app.
• I’ve done the updates, just updated iPhones IOS, each to no avail.
• it might be helpful to say that *when I just put the app in the background and go back to the main phone screen, THEN go back to the background apps, I can SEE the Apps main page, as it should look, if it were to open properly.
• I hope this will help, thank you for working so diligently to correct the issue.

6-27-26 Tried shutting down phone when I only got a black screen after the update. Sadly, that didn’t fix the issue. Please help/fix.
