Poor app UX
This app is marred by a lack of detail and horrendous UX. This app absolutely decimates the battery of my iPhone 14 Pro. Users are forced to manually connect to their piano each time the app is open (as if the average user has multiple pianos lying around to connect with!) - this connection should happen automatically just like with other Bluetooth devices. The metronome function is completely unflexible; the default metronome tick can only be adjusted in volume...but not in tone, nor can unaccented ticks be used for smaller rhythmic intervals, BPMs can also not be entered by hand. Kawai should take a look at other metronome apps for well-thought-out examples. It is a shame that Kawai piano/keyboard owners have to deal with this app.
