RedLaser is pretty much the gold standard for scanning QR and UPC codes. It even generates QR codes.

I've picked up a couple of "where did I leave my car" apps but then I forget to use them so I can't tell you how well they work.

My favorite GPS using app is PeakFinder, but not everyone shares my obsession with knowing the name of any mountain I can see.

Yeah, that could be a problem.

Now I'm wondering if there's a "where did I leave my car" app that can detect when my car ends its Bluetooth connection to my iPhone (i.e. when I turn it off) and records where I am at that time.

Wow. Redlaser's bar-code reader is awesome. Love how it finds location and price options for what I've scanned. Thanks, -t.

(I had forgotten such functionality existed. I was mostly thinking a QR code reader could let me scan those QR codes on train ads.)

What does a "where did I leave my car" app offer over and above taking a photo of the nearest identifying marker? Especially when you're somewhere you can't get a cell or GPS lock?

I like RedLaser, but for some reason it does not work all the time for me. I also like i-nigma for QR codes.

I can't help you with aug reality apps. I like Parkbud to help monitor parking meters.

Well, if you're in a giant parking lot? Or on some side-street blocks away from your destination? Plus, maybe less thinking is involved?

I just type the info into notepad. A26, or whatever.

Holy crap, I am going to start doing that. Brilliant!

The ones I've played around with are basically just GPS markers plus a maps or directional arrow or some sort of navigational aid from "where I am now" to "where I was when I parked the car". I mostly use them (or, more often, wish I had used them) when I park on the street in an unfamiliar neighborhood/city.

I can't think of the last time I've been in a giant parking lot that doesn't have section markers or numbered spaces. I just take pictures of those, making sure to delete them when I'm done.

My camera still works.

That's what's less thinking for me, since if it's so dark my camera can't work, I'm not sure I want to park there. But, as noted, I might not have GPS or cell reception. Those apps wouldn't work in my office parking, for instance. Camera still does.

Okay, to be *totally* honest, I usually write down what every the identifier is onto the parking ticket in a metered lot. But when that's not an issue, camera.
