Find all of your belongings using your smartphone with the Nonda AIKO Finder Smart Rechargeable Tracker. Just attach this device to the gear you lose the most and ring the device to find out exactly where they are. The clever app records your item’s last known location, so you can follow the map to find it. This tracker also works in reverse. With a simple tap, it rings your smartphone so you can find it even if it’s on mute. With its slim and compact design, AIKO fits in your wallet or even on your keychain. It has an impressive volume of up to 90 decibels, so you’ll certainly be able to hear it anywhere. Plus, AIKO lasts for up to four weeks on a single charge and recharges with a standard micro USB cable. The app even lets you know when the tracker is low on battery.
