Too little checked to say Store information only. We haven’t analysed this app or read its reviews yet.
Not yet tested.
The store currently lists version 100.11.13, updated 2026-10-21.
Store screenshots supplied by the developer.
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.…

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured
Not yet tested. No analysis has been run for this app, so there is no version or date to report.
Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
• Next Opportunity now counts down to vitamin D season: 10, 5 and 1 days before the midday sun is high enough again, and on the day • Vitamin D season notifications only go to places where the season actually ends • Session reminders (turn over, window closing, goal) stay correct after pausing and resuming • Removed an unused sun angle setting: the vitamin D window is always when the sun is 30° or higher

d-minder-proWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
