I love the design and the stability of the beats. The app gets better with each updates. I use it for myself and for my students. Just small details that I wish the developer could add is have the 440Hz A to be more continuous sounding and that there are more frequencies ranging from 440 to 446Hz. Another wish I have is having a more diverse ticking sounds. Currently, only the default sound is audible enough to play on top of the metronome. Other sounds are not as attractive as the default. Thanks!
