Bluetooth is the easy way to do HID.
Many Android phones can do USB an adapter cable. Also on Android the earphone and mic jack can be used as a serial jack, with either an old style serial mouse or an adapter cable.
You may be aware most modems were actually software that converted the sounds to and from audio and serial bytes. The modem card was just an adapter for the phone line since it was the software generating the audio signal.
The same software libraries can convert any byte stream to audio for phone's audio jack. I don't know if Apple had approved an app for that, but it's in use on Android where no corporate approval is required.
