### 3/5 — 半音ずつ上下できる上下できるカーソルがあれば

*2022-08-29*

耳を鍛えるために、チューナーではなく発信音に合わせる形でチューニングしています。音量は十分です。ただ、発振音の高さを上下させる際に、指先でスライダをずらして行うのですが、これが極めて使いにくいです。特に半音ずつ上げ下げする場合、片手に楽器を持ち、もう片方の手の指で指先で半音ずつずらすと、グリッサンドで離れた音まで暴走しまうことも多く、ストレスがかなり溜まります。ここはやはり◀︎▶︎のカーソルが必要だと思います。また音を瞬時に止めるボタンも必要だと思います。音叉を使う場合は、ほぼ片手は必ず塞がっている（歌の場合も楽譜を持っている可能性があります）という大前提でユーザーインターフェースを改良していただけると助かります。

### 1/5 — マイクにアクセスしないアプリで使えない。

アプリが音をまったく拾わない。 課金は詐欺みたい。
