Just pop this little pebble on your stuff to know whenever it moves.

We carry so many expensive gadgets and tech around with us these days that it’s not unreasonable to want to bring in some extra security. And if you’re after a theft-preventing, movement-sensing device for life on the go, Stilla Motion can help.

A smooth disc-shaped little device that’s no bigger than a watch face, Stilla Motion will send an instant alert to an app on your phone the moment it gets moved. Whether it’s sitting on your laptop in a café, inside your coat pocket in a restaurant, or stuck to your baby’s pram in the park, Stilla Motion can be the peace of mind you need to get on with your day.

Stilla MotionExactly how sensitive Stilla Motion is depends entirely on your own preferences. Using the app, you can quickly tell Still Motion exactly how much turbulence you want to trigger it, and you can even set Stilla Motion’s built-in speakers to sound an alarm at the same time it alerts your phone. This is a handy little theft-prevention tool, as well as a backup measure in case you don’t have your phone to hand when you get an alert.

Stilla Motion also makes use of geo-fencing, which means you can get an alert if you and the device part from each other over a comfortable distance. Again, that distance is customisable from the app, so you don’t have to put up with annoying alerts every time you go to the toilet and leave Stilla Motion sitting on a table.

Stilla MotionTaking Stilla Motion in the car or on the bus with you? This shouldn’t be a problem. The device has smart algorithms that promise to ignore bumpy rides and save you a backlog of alerts on your phone when you finally hop off the bus or step out of your car.

Stilla Motion is compatible with both iOS and Android phones, but you can use it on your smartwatch too if you’d like wrist-based motion alerts.

If you’re sold, you can grab one from Indiegogo for just $29 (around £22). The campaign is fully funded, so it looks like Stilla Motion should be shipping as planned on March 2017.
