How it works

Three steps, then never again.

  1. Fingers peeling a FindStick off its backing liner.

    Peel and stick

    The adhesive back holds to anything flat and comes off clean.

  2. A FindStick on a dark surface catching daylight from a window.

    It charges itself

    Room light is enough. A lit hallway keeps it running.

  3. A phone showing a directional arrow pointing across a dim garage.

    Find it

    Open the app and follow the arrow.

Stored charge carries it through weeks of darkness.

Where it goes

Anything flat, anything you'd hate to lose.

  • Stick one inside the lid before you ship. It rides along, reports in at every stop, and tells you the moment the box stops moving.

  • Cases, ladders, generators, the good impact driver. Tag the fleet once and see the whole site on one map.

  • Inside the lid, under the liner, on the hardshell. Thin enough that nothing in the bag notices, and no battery to explain at security.

  • Warehouse light is more than enough. Tag crates, totes, and returnable containers and stop counting them by hand.

  • Stick it to the back. Ring it from your phone and stop taking the couch apart.

  • Between the case and the phone. Works when the battery is dead and the phone has gone quiet.

Questions

Does it work in the dark?

Yes. It stores enough charge to keep reporting for weeks without light.

How much light does it need?

About as much as a lit hallway. Ten minutes a day is plenty.

What if it's far away?

Other FindStick phones nearby pass its location back to you.

Will the adhesive damage anything?

It peels off clean. Four spare pads come in the box.

Is it waterproof?

IP67. Rain, snow, and a dropped cooler are fine.

Who can see my things?

Only you. Locations are encrypted end to end, and the phones that relay them can't read what they carry.

What does it cost?

$29 for one. $79 for four.

When does it ship?

Spring 2027. Reservations ship first.
