About this app

Trip Wire turns your Android phone into an invisible laser trip wire. Point the camera at a doorway, a hallway or your desk, tap Activate, and an alarm sounds every time something moves in view.

GREAT FOR
• Finding out who sneaks into your room or raids the fridge
• Hearing when someone comes through the door
• Pranks and party games
• Keeping an eye on pets

KEEPS WATCHING IN THE BACKGROUND
• Keeps working when you leave the app or turn off the screen
• An ongoing notification shows how many times the wire has been tripped
• A countdown gives you time to step out of view before it starts

9 ALARM SOUNDS
Airhorn, alarm, bomb, buzzer, cat meow, ding, dog bark, gunfire and mad cow, with adjustable volume and a test button.

MAKE IT FIT YOUR SPACE
• Sensitivity: from very low to super high
• Time between sounds: from 0.1 to 60 seconds
• Noise reduction to ignore flicker and small changes
• Front or back camera
• Live preview to aim the camera

PRIVATE BY DESIGN
The camera image is analysed only on your phone. Nothing is recorded, saved or uploaded, and no account is needed.

Trip Wire is available in 26 languages. It is free and shows a small banner ad. You can change your ad privacy choices at any time from Privacy settings in the app.
