Intruder selfie and snoop detector
See who tried to use your phone when you were away.
See who unlocked your phone
Intruder Selfie answers a simple but unsettling question: who has been on my phone? When someone picks up your iPhone and tries to get past the lock screen, WTMP can take a photo on the wrong unlock attempt using the front-facing camera. It works silently, like a hidden eye or crook catcher — the snooper has no idea a picture was taken. When you come back, you don't have to wonder who unlocked your phone; you can see their face.
Each capture is stored privately on your device with the time and date, so you get a clear, timestamped log of every attempt. This is screen unlock monitoring in its most useful form: not just a count of failed attempts, but actual visual proof of who tried to get in.
Why a snoop detector matters
Not every threat is a stranger. The most common form of privacy invasion comes from people close to you — a partner who copied your passcode, a sibling, a roommate or a coworker who waits until you leave the room. They count on you never finding out. A snoop detector removes that confidence. Knowing an intruder selfie might be waiting for you is a powerful deterrent, and if someone does try, you finally have evidence instead of a gut feeling.
What you get with Intruder Selfie
- Photo on wrong unlock — a front-camera shot the moment a failed attempt happens.
- Timestamped log — every attempt recorded with the exact time and date.
- Silent, stealth operation — the snooper sees no flash, sound or warning.
- Screen unlock monitoring — awareness of when and how often someone tries to access your phone.
- Private storage — evidence stays on your own device, not on someone else's server.
Best situations to use it
- Shared homes, dorms and offices where your phone is often left on a desk.

How to set it up
- Open WTMP and enable the intruder selfie / snoop detector mode.
- Grant camera access so the app can capture a photo on a failed unlock.
- Set a secure PIN and a short Auto-Lock time so the phone locks quickly when you walk away.

- Return and review the timestamped log to see exactly who tried to unlock it.
Privacy-first by design
Intruder Selfie is about protecting your own phone, not spying on anyone. WTMP does not read your messages, photos or chats — it only records attempts to access your device so you stay in control of your privacy.
