If any Chipolo Community member running the Chipolo app on their phone comes within range of your Chipolo, and it has been Marked as Lost, the Chipolo app on their phone will send an anonymous update of that Chipolo's location to your phone, using the Chipolo system. The Chipolo app will notify you when another user comes within range of a Chipolo you've marked as lost to help you find your lost things even if you're not nearby.
As the Chipolo Community grows with each new user, the more effective it becomes in finding your lost item.
