Do you lose your keys often? Or maybe your wallet or a bag? The ANKR Smart Tracker may be the solution you've been looking for. This Smart Tracker is thin and lightweight and can easily be attached to a slew of items so that you can find them when you lose them. ANKR can communicate with your smartphone, so you'll be able to find exactly where you left that item, as well as knowing that you left something behind. The ANKR has a replaceable battery as well, and uses Bluetooth low energy to connect with your smartphone. This way it doesn't use much of your smartphone's battery.
Through the ANKR app - which is available on both Android and iOS - you'll be able to define a safe zone for the item that you have the smart tracker attached too. Maybe you don't want to be notified when you leave something in the car, and you go into your home. You can set up that area as a safe zone. The app also shows you the GPS location for the items, so you are able to check the most recent location pretty easily. This smart tracker is pretty cool, and cheap. Something that's definitely worth having around if you are often losing things.
