PinDrive: find where you parked in Augmented Reality
So, it works like this — you park, take a few steps away from your vehicle, then boot up PinDrive, look at your car through the phone's viewfinder, and “pin” your car's location. Later, when you are looking for your parking spot, open up PinDrive and look at the world through the app's camera. You will see your virtual pin somewhere in there — that's where you parked your car, kaboom!
Of course, there have been parking assistants before this one and before ARKit. But the classic solution only uses your GPS and pins your car on a map. So, the AR solution is a bit more precise. Check it out.
