D-Minder helps you maintain optimal vitamin D levels by tracking sun exposure, supplements, and dietary intake. Using real-time solar position and satellite ozone data, D-Minder calculates how much vitamin D you produce during each session.
Fixed: for some users, tapping Sun Session showed only a blank screen — and reinstalling didn't help, because Android's automatic backup kept restoring the stuck state. The app now detects and clears that leftover state on launch, automatically. Also fixed: session location and ozone are now saved with each session.
