### 1/5 — 弾いてないのにメーターが動く

*2026-03-28, version 2.3.6*

弾いてないのにメーターが動く。弾いても反応しない。
全く使えません。

### 4/5 — Not horrible but not great

*2021-06-26, version 2.2.7*

So I like the idea for a 5 and 6 string bass, however while tuning the B string to anything other than B the tuner either doesn’t work OR it just flips from too high to too low. You can never seem to get it in the middle

### 4/5 — 経験者向け

*2021-06-09, version 2.2.7*

高低差を指示してくれて、上下ピッタリにさせると言う物で至って普通

ただ少なくとも自分の耳で聞くこともせず、切れるまで巻いちゃう様な永遠の初心者には向いてない
向いてるのがあるのかすらわからんが

### 2/5 — ほならね

*2019-05-16, version 2.1.5*

自分が作ってみろって話ですよ

### 2/5 — もっといいアプリあるよ

*2019-04-18, version 2.1.5*

こんなアプリ使うよりももっといいやつあります。分かりづらいです。使える人には使えるんじゃない？僕は使いづらいと思ったけどね。

### 1/5 — 使えない ゴミすぎる

*2019-04-02, version 2.1.4*

1弦巻いててもずっとDのまんまで最後には弦が切れた。
アプリの質を上げてくれ

### 5/5 — 無料でも

*2018-02-11, version 1.9.1*

最低限の機能はしっかりと揃っており、大変使いやすいです。ありがとうございます！

### 5/5 — Low Aがデフォルトで合わせられる

*2017-06-09, version 1.6.6*

五弦ベースの変則チューニングでLow Aが設定できるのがとてもありがたい。

### 5/5 — いいね〜

*2017-02-11, version 1.6.0*

ドロップD、半音、1音、1音半下げまで対応してるので優秀！

### 5/5 — 最高

*2016-10-19, version 1.5.3*

これは本当便利です！
半音下げとか細かいチューニングもでき、5弦6弦ベースの設定もありますし！
他のチューナーも無料の多いけどベースは無かったり課金とかだったりするので、ベースをこれから始める人には楽器屋でチューナー買わずにこれがあれば充分だと思いますよ！
まぁベース初心者の自分が言うのもなんですがw
けど、オススメです(´∀｀*)
