This is what AR was made for - iOS app Pixie helps you locate almost any item in AR
Let's be honest here... How often do you lose your keys or wallet? If you're anything like us, miniature black holes are likely an integral part of your humble abode's interior, slurping anything remotely important in our everyday lives that ventures past their event horizons. Humiliating.
Luckily, thanks to augmented reality, item locating became way cooler than it used to be.
The premise is quite simple - you get Pixie, you attach it to an item you really, really, really don't want to lose, and you're pretty much set. Unlike more common Bluetooth-based item trackers of the same ilk that use only audio signals to guide you, Pixie utilizes both AR and audio cues: it allows you to assign a cool 3D avatar to the object you're locating and keep track of it thanks to those nifty Pixie Points. You can even have the distance to the tracked object shown on screen, exact down to inches, making locating important thingies easier and more convenient.
That said, Pixie has been around for a while now, but with augmented reality becoming more and more mainstream now that iOS 11 is out, the item-locating service became that much more useful and pleasant to use.
Pixie Points have a 12-month battery life and measure up at 47mm x 35mm x 3.2mm and are waterproof up to around 3ft. They have a 150-feet outdoor range and 30-50 feet indoors, which should be pretty much sufficient for almost anyone's needs. Prices start at $29.99; Pixie is available on both Amazon and the company's own website. Pixie will also soon make a rather big step and arrive on Android.
Here's a video demo that shows how Pixie does the magic:
