Works for Family Medical Diary whether or not it has its own passcode. No download needed.
Touch and hold Family Medical Diary's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Family Medical Diary behind Face ID, Touch ID or your passcode; choose Hide and Require Face ID instead to move it into App Library's Hidden folder as well.
Lock Family Medical Diary with Face ID
- Find Family Medical Diary on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Family Medical Diary now asks for authentication every time it opens.
To test it, close Family Medical Diary from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Family Medical Diary in App Library
- Touch and hold Family Medical Diary's icon and tap Require Face ID.
- Choose Hide and Require Face ID instead of Require Face ID.
- Confirm. The icon leaves your Home Screen and moves to the Hidden folder at the bottom of App Library.
- To open it later, swipe to App Library, tap Hidden and authenticate.
Hiding also locks the app. To undo either, touch and hold the icon again and choose Don't Require Face ID.
Why lock Family Medical Diary?
Family Medical Diary is a medical records app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Medical-record apps hold diagnoses, prescriptions and insurance details. Patient portals from your provider are bound by health-privacy rules in a way most standalone apps are not.
Medical apps may hold the most sensitive data on your phone. Whether US health-privacy law applies depends on who runs the app, not on the App Store category.
A lock answers one question — who can open the app on this iPhone. It does not change what Family Medical Diary sends to its developer; for that, see Family Medical Diary's full privacy report.
