iOS app Blind Compass https://github.com/mltony/blind-compass

I am blind and I developed this auditory compass for blind people that communicates your heading as two tones - musical interval between them encodes your heading. It helps white cane users not to get confused in space or walk straight across large open space by locking heading. It also makes me look like a lunatic, because I put iPhone into phone holder that I sawn to my hat to provide most accurate heading information.

The app is free, but I have to pay for Apple Developer subscription to keep the app in the app store.

This is brilliant! It reminds me of the North Paw anklet, which I think dates from back when phones didn't include magnetometers.

If I keep my phone in a hip holster but get the audio over a Bluetooth earbud, is that likely to be useful? Do you wear it on your hat so you can swivel your neck and "probe" the compass response, or because you get better results up there in some other way?

I do use it with bluetooth headphones - bone conductance headphones, so that I can also hear the street. I tried to put my phone in the pocket, but then heading fluctuates with every step. I assume this might be enough for someone, but I prefer to hear accurate heading, wich allows me to walk straight comfortably.
