Chipolo ONE Bluetooth tracker is perfect for finding keys, backpacks, or other items in seconds. With the Chipolo app, you can track where your lost item was last located (within range) and play a loud sound from the tracker. If your phone is lost, double-tapping the Chipolo will play the sound on your phone, even if it is on silent mode. With the widget from the Chipolo app, you can directly play the sound from your home screen, and with a compatible phone or smart speaker, you can also use voice control. Chipolo ONE Bluetooth tracker can be shared with other users of the app, doubling the effectiveness of searching for your items. The app now also sends a notification before you need to search for lost keys or your wallet: When notifications are enabled, the Chipolo app reminds you to take them with you when you go out of range. The notification you receive on your phone is a short ringtone combined with a text notification from the Chipolo app. If your phone is on silent, it will vibrate instead of sounding the ringtone. Chipolo ONE model is available in six bright colors that complement your keys, bag, or backpack.
