But that would still possibly present a problem for serious government use where it can't have an antenna of any form in it.
Unless they significantly improved that app, in the last eight years or so, it may not be a great loss.
I guess modern integration has put Bluetooth and other devices together with GPS in one module.
So I delved into the fascinating and still-extant world of standalone MP3 players. I selected a SanDisk Clip Jam, and it had like 8GiB onboard, an sdcard slot of course, an FM radio receiver, and really cool firmware. It was very simple, robust, extremely light, compact and portable. It was the size of a matchbox and it could clip onto your sleeve or belt, or whatever.
And it met all the requirements. It had no BT, no WiFi, no sensors of any kind, and it did that job very well of music playback, however I found it. And it could indeed store arbitrary files, so being the kind of hacker I am, I stashed a copy of my password manager encrypted database, plus a full install MSI of the application. And I included some README.txt that would indicate who owned this thing and how to return it, if lost.
I really miss that thing for its elegant simplicity. With the Swiss Army Knife nature of smartphones, I still long for the specialization and compartmented functionality of separate devices.
All of my Nikons are wireless-free. Some of them are even battery-free.
Yes, evaluate market demand by making it more expensive and doing 0 marketing. /s
Am I crazy in thinking that doing it this way is close to meaningless?
