Motion alarmLift it, and everyone hears about it.

Someone picks your phone up off the table and the siren fires at full volume, whatever the phone is set to. A live meter shows how hard a lift has to be, so a bump is not a theft.

How it works

A phone alarm that goes off when it is picked up, not when the table shakes.

01

Open it, arm it

One tap. A three-second countdown so the alarm does not catch your own hand.

02

A meter you can see

The live reading sits against a trip line. Tap it, bump the table, lift it: watch the difference before you rely on it.

03

Stops for you only

Your face or your PIN. The stop screen is a plain passcode with no app name.

FAQ

Questions people ask

Not answered here?

A person replies, usually within a couple of hours. The promise is one working day.

01How loud is the siren?

As loud as your phone can go. It plays on the alarm channel through the loudspeaker, which ignores the media volume and the silent switch.

02What if it goes off by accident?

Stop it with your face or your PIN in about a second. The countdown and the live meter are there to prevent false alarms in the first place.

03Will it drain my battery?

No. Shoo listens to the motion sensor, which uses almost nothing. A full day armed costs roughly the same as ten minutes of video.

04Does it work on iPhone?

Yes. iOS does not let apps relaunch after a restart, so Shoo reminds you to re-arm instead.
