I came across this area recently while trying to build an iOS app that could reliably detect knocks or taps on the body of the phone, I was ultimately unsuccessful but I learned a lot about collecting and analysing microphone and gyroscope data. Also built some nice tooling for collecting live iOS sensor data and transmitting it to prometheus/grafana over mqtt.

That sounds interesting. A cool project would be to inspect gyroscope data when the iOS keyboard is in use. Maybe it would be possible to create a keylogger based on it. I guess it would depend on how good the data is and which keyboard is being used. I know that this is possible on Android.
