How to Know If Someone Unlocked Your iPhone
Last updated:
Your iPhone does not keep a list of who unlocked it. If you suspect a partner, roommate, sibling or coworker went through your phone, you can look for clues in iOS — or install CrookCatcher - WTMP Anti Theft to get a photo of whoever does it next time.
Step 1: Check the clues iOS leaves
Screen Time. Settings → Screen Time → See All App & Website Activity. Look for app use at times you weren't using the phone.
Recently opened apps. Swipe up and pause to see the app switcher. Apps you didn't open are a red flag.
Messages, Photos and Safari history. Read messages you never opened, new screenshots, or browsing you didn't do.
These only tell you that someone used your phone — never who.
Step 2: Catch them next time with CrookCatcher
CrookCatcher - WTMP Anti Theft answers the question iPhone can't:
- Silent front-camera intruder selfie — no flash, no sound
- Time and GPS location saved with every capture
- Instant alerts, including email with the photo
- 10-second silent intruder video (Pro)
- Fake home screen that traps snoopers; your real screen opens with a secret PIN (Pro)
- Keeps protecting in the background, even after the app is closed
It takes about a minute to set up and is free on the App Store. Also available on Android as WYTMP.
Frequently Asked Questions
Can I see if someone unlocked my iPhone?
Not directly. iOS keeps no unlock log and never shows who opened the phone. You can look for clues in Screen Time, recently used apps and Photos, but to get proof — a photo of the person, the time and the location — you need an intruder-detection app such as CrookCatcher - WTMP Anti Theft.
Does iPhone take a picture when someone enters the wrong passcode?
No. iPhone has no built-in intruder selfie. Apps like CrookCatcher - WTMP Anti Theft add this: they silently take a front-camera photo when someone tries to use your phone and save it with the time and GPS location.
How do I check Screen Time to see if someone used my iPhone?
Open Settings > Screen Time > See All App & Website Activity and choose Day. Usage at times you weren't holding the phone — for example at night — shows someone else used it. It shows which apps were opened, but not who opened them.
What is the best app to see who unlocked my iPhone?
CrookCatcher - WTMP Anti Theft (also called WYTMP) is built for this. It captures a silent intruder photo, optional 10-second video, time and GPS location, sends you an alert, and keeps working in the background. It is free on the App Store with an optional Pro plan.
Will the person know they were photographed?
No. There is no flash, no shutter sound and nothing shown on screen. Photos are stored privately in the app.
