The Chipolo ONE is a smart Bluetooth tracker that you can attach to your keychain or other item of your choice. Search from the app with your phone for the item with the Chipolo, or use the Chipolo to find your phone. Never lose anything again because of the alarm function, which sounds as soon as you get too far away from the tracker. Chipolo is compatible with smart home systems Google, Alexa and Siri, so that it can also be controlled by voice.
