Trackr, Mynt, etc: Recommend me a Find-my-Device thingie

In My Humble Opinion
1

Mynt appears to be a combo of small electronic device + software application (for iPhone or MacOS or Android) to let you find your missing whatever-it-is that you attached the device to. It uses Bluetooth, and my understanding of Bluetooth, admittedly limited since I’ve never used it for anything, is that it is a nearby-vicinity protocol. So it would find something you misplaced here in the apartment but it isn’t going to locate something you left in the Javits center across town, right?

Trackr may or may not be a more robust version of that kind of thing, something that you put in your wallet for example and it finds your wallet, maybe over a much broader area, but it is cellphone-only for the software app.

What I want is a device I stick inside my wallet and the next time I lose or misplace my goddam wallet on the subway, or it falls out of my pocket who-knows-where, left it uptown in my girlfriend’s apartment, or whatever, I can do the equivalent of opening Google Maps and seeing a GPS identifying crosshair telling me “here it is”, regardless of how far away “here” happens to be, and I want the software to run on MacOS X. I do not have a smartphone.
Recommend me something?

I think what you’re going to run in to is that any device needs a way to access the internet so it can tell Google Maps (or wherever) where it is. With devices like Trackr and Tile, they use crowd GPS - so when anyone with a smartphone that has the app installed walks close enough to the device to detect it, its location is noted and uploaded.

By not having a smartphone, you are not part of the network. None of these things would work for anyone without enough users to get pretty good coverage. The devs need you to be carrying a device that can detect and report the location of their tracking devices.

Unless I’m fundamentally misunderstanding how these things work, my understanding is that they reply on participation (use of the app) and are unlikely to support users who can’t participate.
