How to Lock Blood Pressure Tracker on iPhone

iOS 18 Face ID lock and Hidden folder · App Sub 1 LLC · checked November 2026

Time needed
4 taps
Needs iOS 18 or later

Works for Blood Pressure Tracker whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Blood Pressure Tracker's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Blood Pressure 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 Blood Pressure Tracker with Face ID

  1. Find Blood Pressure Tracker on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. Blood Pressure Tracker now asks for authentication every time it opens.

To test it, close Blood Pressure Tracker from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide Blood Pressure Tracker in App Library

  1. Touch and hold Blood Pressure Tracker's icon and tap Require Face ID.
  2. Choose Hide and Require Face ID instead of Require Face ID.
  3. Confirm. The icon leaves your Home Screen and moves to the Hidden folder at the bottom of App Library.
  4. 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 Blood Pressure Tracker?

Blood Pressure Tracker'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.

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 Blood Pressure Tracker sends to its developer; for that, see Blood Pressure 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 Blood Pressure Tracker opens
  • Hide message previews in notifications
  • Keep Blood Pressure Tracker's content out of Spotlight and Siri suggestions
  • With Hide, remove the icon from the Home Screen

It does not

  • Stop someone who knows your passcode
  • Encrypt or change how Blood Pressure Tracker stores data
  • Sync to your iPad or other devices
  • Remove Blood Pressure Tracker from purchase history or Screen Time reports

Don't see Require Face ID?

  • Update to iOS 18 or later in Settings › General › Software Update.
  • Make sure a passcode is set in Settings › Face ID & Passcode; the lock needs one.
  • Some Apple apps (Settings, Calculator, Camera, Maps, Find My, Clock) cannot be locked or hidden.
  • If your iPhone is managed by work or school, the option may be restricted.

Other settings worth checking for Blood Pressure Tracker

  1. Tracking

    Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.

  2. Health

    Health app › your profile picture › Apps › Blood Pressure Tracker. Turn categories on one at a time; the app cannot tell which ones you declined.

  3. Notifications

    Settings › Notifications › Blood Pressure Tracker › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

FAQ

Does Blood Pressure Tracker have its own passcode?
Some apps offer an in-app PIN or biometric lock in their settings. The App Store privacy label does not say whether Blood Pressure Tracker does; the iOS 18 lock works regardless.
What happens to Blood Pressure Tracker's notifications when it is locked?
Locked and hidden apps do not show message previews or content in notifications, and their content does not appear in Spotlight search or Siri suggestions.
Can someone who knows my passcode open a locked app?
Yes. If Face ID fails, the lock falls back to your device passcode. Keep the passcode private if the lock matters to you.
Is a locked Blood Pressure Tracker encrypted?
The lock controls who can open the app on this iPhone. It does not change how the app stores or syncs data. Encryption depends on the developer and on your device passcode.
Why can't I see the Require Face ID option?
You need iOS 18 or later. Some Apple apps such as Settings, Calculator, Maps and Camera cannot be locked or hidden.
Does hiding Blood Pressure Tracker remove it from my purchase history?
No. Hidden apps still appear in App Store purchases and in Settings › Apps, and Screen Time reports still include them.
