Motion Alarm

Motion Alarm turns your phone into an anti-tamper alarm.

Place it anywhere, arm it, and if someone moves it, the alarm goes off.

No accounts. No sign-up. Your settings and alarm log never leave your phone.

HOW IT WORKS

Pick a preset, press Set Alarm, and place the phone during the countdown. The screen goes black and monitoring begins. Any movement fires the alarm. Press and hold to disarm.

PRESETS

Desk: on a table while you step away. Sensitive, short timers.
Transit: in a bag on a train. Ignores vibration, catches a real lift.
Door: on a handle or in a drawer. Tuned for rotation, 20s to leave.
Min and Max: the two ends of the scale, to tune from.

WHEN IT FIRES

• Looping siren at full volume
• Screen and flashlight flash your chosen pattern: Default, Solid, Strobe, Beacon or SOS
• Hold-to-disarm up to 20 seconds, so nobody silences it in a hurry

REPEAT MODE

The alarm silences itself after a set time and re-arms once the phone is still. One night of disturbances is recorded, not one endless siren.

ALARM LOG

Every session is logged: when you armed it, what triggered it and how hard, abandoned disarm attempts, and when it was disarmed.

CONTROLS

• Acceleration and gyroscope sensitivity
• Time to arm and time to disarm: 1 to 20 seconds
• Warning period: a silent 3-second countdown, cancelled with one tap
• Silent alarm and flashlight on or off

Live charts show the last 20 seconds of movement against the trigger line, so you can see exactly how much it takes.

ADS

Free with ads, never while the alarm is armed or firing. Remove them with a one-time in-app purchase.

PRIVACY

Ads are provided by Google AdMob, which uses your advertising ID. Camera permission is used only for the flashlight. No photos or video are ever captured.

Keep the app open while it monitors. Raise your volume before arming.

Set it. Leave it. If it moves, you'll know.
