Works for Symptom Tracker whether or not it has its own passcode. No download needed.
Touch and hold Symptom Tracker's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Symptom Tracker 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 Symptom Tracker with Face ID
- Find Symptom Tracker 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. Symptom Tracker now asks for authentication every time it opens.
To test it, close Symptom Tracker from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Symptom Tracker in App Library
- Touch and hold Symptom Tracker'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 Symptom Tracker?
Symptom Tracker is a health tracker, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Health trackers collect symptoms, vitals and habits. In the US, most consumer health apps are not covered by HIPAA, so the privacy policy is your main protection.
Health and fitness apps can read Apple Health data only for categories you approve, one by one. What they collect themselves is shown on the label.
A lock answers one question — who can open the app on this iPhone. It does not change what Symptom Tracker sends to its developer; for that, see Symptom Tracker's full privacy report.
What the lock does and does not do
It does
- Ask for Face ID, Touch ID or passcode every time Symptom Tracker opens
