Losing your keys and phone is easy to do -- especially with children! The Chipolo Classic allows you to attach the small, circular device to anything and connect via bluetooth to the Chipolo app. Ring Chipolo from the app or double press it to ring your phone when you can't find it. Even if it’s on silent! The app also helps you to find your missing items -- it remembers when and where you last had them. Do you share keys with loved ones? You can even share Chipolo accounts so that more than one party can track the items!
