Works for 1st Phorm whether or not it has its own passcode. No download needed.
Touch and hold 1st Phorm's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts 1st Phorm 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 1st Phorm with Face ID
- Find 1st Phorm 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. 1st Phorm now asks for authentication every time it opens.
To test it, close 1st Phorm from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide 1st Phorm in App Library
- Touch and hold 1st Phorm'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 1st Phorm?
1st Phorm's privacy label lists health and fitness — the kind of data 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 1st Phorm sends to its developer; for that, see 1st Phorm's full privacy report.
