Hey there! I empathize that not talking enough is just as difficult.

I have had this on my radar as well and, in a way, you can totally use it to track your non-speaking as well.

Here's an idea: What if there was a toggle for your scenario and the count-down of "other people talking" started when you're silent.

The colors on timeline would be inverted, you'd see your "airtime" as a few gray dots.

What do you think? Would this be helpful?
