### 1/5 — 二重課金

*2026-04-06*

なぜか2回購入したが、改めて課金を要求される
どんなシステムか?

悪いことは言わない。
他のアプリを探した方が良い。
なぜなら、私のように超不快になるから。

希望が有れば、クレジットの引き落とし明細をアップロードするが。

積極的にアプリは課金しているが、こんなの初めて。

### 2/5 — Anger

*2024-03-26*

It heard me talking, but not my bass.i had to get right up to it but then it was just extremely jumpy at the end I felt my bass was even more out of tune than before.

### 5/5 — Very good tuner

*2024-02-28*

I use this app almost any time I need to tune my bass and it sounds very good but sometimes the pitch on the app just changes still good though 👍

### 1/5 — Ea sports its in the game

### 1/5 — 低音提琴

*2022-10-18*

非常差

### 1/5 — All it did was make noise that’s it

*2022-08-23*

Don’t download it

### 1/5 — Viele zusätzliche Apps sind notwendig, damit man anfangen kann

*2022-05-11*

Seltsames Marketing. Wenn man diese App benutzen will, muss man mindesten zwei zusätzliche kostenpflichtige Apps zur Starterapp kaufen. Da das vorher nicht transparent gemacht wird, finde ich die Verkaufsstrategie unredlich.

### 5/5 — Funktioniert gut aber…

*2021-11-24*

Insgesamt bin ich mit der App zufrieden aber manchmal wenn ich meinen Bass gerade stimme wechselt das Stimmgerät  z.B. zwischen 36.00 und 79.00 ansonsten ist sie sehr gut und ich kann sie nur empfehlen 😊

### 1/5 — Tuner app

*2021-09-16*

Nothing works and I had do wast my money to get another app
