The only way I could see the frequency is if i Calculated it from AC voltage in graph mode: buffered, and calculate it from the graph time…
It would be so simple to program into the app to do this, but it seams like they don’t care enough about the soft to make this small adjustment.

I’d like to ask Mooshi Meter programmers (who wrote the app, and has the source code), to implement the calculation (simple math) and an option in the roll down menus for frequency…

Thanks.
Szabi.
