It doesn’t work...
On my phone, there is no way to start and stop it. Pity... And there is no need to collect a bunch of user data for offering this metronome. Nothing is really free after all... ...do you think I wouldn’t try it the ‘real’ way? I said it DOESN’T WORK ON MY PHONE and I mean it. It’s not the first time I use a metronome on my phone.
