Who it's for

A phone motion alarm for hotel rooms and shared rooms

When you travel, the phone often charges on a nightstand or a shared table while you shower, sleep or pack in another corner of the room. In a hostel dorm or a shared office you cannot always keep it in your hand. You want to know right away if someone picks it up or pulls it off the charger.

What MotionGuard does for them

  • Arm it before you step away and it sounds a local alarm if the phone is moved.
  • With Pro, it can also react when the charger is pulled, as long as the phone was on power when you armed it.
  • A settle delay gives you time to put the phone down and walk away before monitoring starts.
  • It needs no account and no location, camera or microphone permission, which matters on a phone you carry everywhere.
  • Back in the room, the local history tells you when it was armed and what triggered it.

Who it is not for

It is not a way to find a phone that was taken. It does not track the device or prevent theft, it only makes noise near the phone.

Questions

Is there an iPhone version?

Not in the sources. MotionGuard is listed on Google Play for Android phones.

Will my watch always get the alert?

No. Watch alerts are not guaranteed and depend on connectivity. The phone alarm is the one to rely on.

Does it work with a Wear OS watch?

Yes. A compatible Wear OS watch shows the phone's latest MotionGuard status and a status Tile. Wrist alerts after a trigger need Pro.

Will it go off if someone unplugs my charger?

Only with Pro, and only if the phone was connected to power when you armed it. If charging is unavailable, the app shows that state.
