Ok for tuning by ear, but buggy

It’s useful to hear and see the names of different traditional scales for koto tuning, but it’s not useful to see if your notes are flat or sharp, and audio bugs make it hard to use as intended.

There is constant buzzing audio feedback when using the app, for the tuner (which disrupts tuning) and also the metronome. It looks like when I have tuning set to 442 hz, the app always registered the note as sharp. When I try to set it to 440 hz, the app automatically jumps back to 442.

As feedback, it would be helpful if the names of the scales had an option to read them in romaji or furigana.

すごい

とても正確で、琴の全てのチューニングが、このアプリ1つでできます。平調子以外のものが欲しければ、買えばいい。240円で全ての機能が手に入るのは、安いと思う。琴のチューナー持ち歩かなくていいし、それを買うよりものすごく安いよ。
