So I want to play table tennis with my cousin and we use a counter app so that we don’t have to count ourselves. This App also has a function were you can connect your AirPods with the phone and one person has one AirPod and the other has the other one and every time one person double taps on his AirPod, his counter on the app goes one up. So it’s very practical. But this function costs money. But I thought t o Myself that there must be a way to make the same function myself. So if anyone has an Idea how to do this or where I can ask for help, let me know :)
