Yes I would too, but I don’t know of any phones that support better than 1Hz updates. Take it up with phone/GPS chipset companies.
To be honest I kinda of gave up on audio comments, I was finding it hard enough to keep track of a bunch of stuff in my head to do with mapping out streets, also focusing on the road/other drivers/not having an accident
The current app lets you pause recording, but starting a new file might be better.
If it acts like all other key events on the phone it should be trappable, but I’ll have to play with it to find out.
