The whole thing, end to end, with nothing hidden.
Point your phone camera at it. A page opens. There is nothing to install and no account to create — ever.
Contact the owner, report that you found it, or use the emergency option if the owner has enabled one.
Say where you found it. You can attach a photo and share your approximate area — both optional, and the area is rounded to about a hundred metres.
The owner is notified straight away and replies in the same place. They never see your phone number, and you never see theirs.
Your keys, your bike, your dog’s collar. Give it a name you will recognise.
Every item gets a unique code straight away. Print the QR yourself, or order a proper tag built to survive weather and wear.
Nothing to charge, nothing to pair, no battery. It works with any phone camera in the world.
The public page changes to say the item is lost, with your message and an optional reward. Turn it off the moment it comes back.
