アプリ自体は良い

最近cleanboostproとURLに入った「ウイルスに感染している」というアラートが出る悪質な広告バナーが表示されるようになりました。アプリ自体はいいので悪質な広告が出ないようにして欲しいです。赤いメールアイコンがずっと点滅していてかなり目障りです。

Most perfect Tuner I’ve ever tried

Love love love love love

Eh

It can never register the E or A string of any of my 3 acoustic guitars

★★★★★Sep 25, 2026
クソ広告がうるさ過ぎる

アプリ自体は悪くないが クソ広告のせいで音が途切れます。 本末転倒で長く使う気には慣れません。 クソ広告を辞めさせる欄も見当たらないので、 改正を願います。

★★★★★Sep 18, 2026
Misrep

It’s a paid app, which you don’t find out until after you’ve downloaded it. I don’t mind paid, but I I don’t care for misrepresentations. I deleted it immediately.
