Metronome
The metronome is very difficult to start/stop. The metronome symbol is very tiny icon in the upper left corner of the phone. The touch area is so small it takes a lot of tapping, pressing in that tiny area to get it started. A larger area for activation, for all the functionality, would improve the usefulness of this app. Also, a lower tone or selection of tones would be more pleasing to the ear instead of a high pitched screech. iPhone 12 Pro Max, IOS 14.3.
