### 1/5 — Unnötige InApp Käufe

*2024-06-28*

Eigentlich wollte ich die App nur testen. Durch den Button für Einstellungen gelangte ich nicht in Einstellungen, sondern tätigte ohne dass ich es wollte, einen Kauf. Dabei wurde nicht gefragt, ob ich tatsächlich diese Aktion tätigen wollte.
Die App selbst ist eher langweilig und was die App-Entwickler in eine Menge von Apps gepackt haben, ist unnötig. Es hätte für die Saiteninstrumente eine App gereicht. Ein einfacher Gitarrentuner vermag die vielen Saiteninstrumente exakt zu kontrollieren; wieso sollte so etwas nicht auch mit einer App möglich sein.

### 3/5 — Good, but not great

*2021-01-24*

This is an okay app for tuning a guitar, but it is lacking some functions that would make it more useful - mainly chord charts. I use mandolin tuner which includes a chord charts that is very useful. Another glitch is that the 2nd harmonic of the string being tuned displays about half of the time. Mandolin tuner doesn’t have that glitch. It’s a pity since I also paid for the in app purchases.

### 1/5 — 使い方がわからないです…

*2020-05-06*

半音チューニングがしやすそうなので購入してみましたが、チューニングが合ってそうなのに合ってないような判定になったりして挙動がよくわかりません…購入して損しました。

### 5/5 — Easy!!!!

*2020-04-11*

Easy, accurate and worth every penny!!!

### 3/5 — Kommt aus dem Kalibrierungsmode nicht zurück ...

*2019-06-08*

Ich muss bei meinem „neuen“ iPad die App immer neu starten. Das nervt bei einer bezahlten App. Habe gerade ein Projekt mit 444 Hz und kann das nicht schnell ändern, weil das Programm immer hakt...

### 5/5 — 最好用的调音app

*2018-05-04*

好用。

### 5/5 — Tuner

*2017-11-23*

Depois que a gente pega a manha, fica excelente.

### 5/5 — Love it

*2014-09-09*

This app is simple to use and very accurate. Great stuff!

### 2/5 — Impossible!!

*2013-09-28*

I have no idea how to make it work. I think I don't know how to do it
