Eureka is a practical little tag that helps you find and keep track of important items like your house key or wallet. In addition to other functions, Eureka allows you to quickly locate an item in your bag or your parked car. Furthermore, it serves as a useful accessory for finding your smartphone by making it ring: to activate this function, simply hold down the emergency button on the tag. To use Eureka, just download the app for iPhone and Android, which shows you the exact location of the item on a map and makes the device ring until it is found. With the adjustable "Comfort Zone" feature, the Eureka app also helps remind you to take the item with you when you physically move away from it.
