### 1/5 — 骗子

*2024-06-29*

我明明免费获取的，使用还要另外给钱，作者注销全家户口本，这是欺诈行为，必须要球下架。

### 5/5 — 怎么用啊

*2024-06-23*

麻烦问一下开发者，这个要怎么使用呢

### 1/5 — Vorsichtig, der letzte Dreck!

*2022-03-30*

Funktioniert nur selten und wenn, dann wird nur im bruchteil einer Sekunde die Frequenz angezeigt.
Dann lieber das Geld aus dem Fenster direkt werfen.

### 1/5 — It doesn’t work

*2021-12-13*

It doesn’t work at all

### 5/5 — Très pratique 🙌

*2020-09-29*

Tres Pratot

### 5/5 — Easy to use

*2020-09-23*

Nicely done, thank you.

### 1/5 — Not what I expected.

*2020-02-11*

Most tuners have a dial to show if pitch is too high or too low. This only shows the pitch # and a beep when proper pitch is attained.
Not as user friendly as some. Regret the purchase

### 1/5 — Vorsicht!

*2018-12-01*

Wir haben die violin tuning app gerade für EUR 3,xx
geladen und es funktioniert gar nichts ausser einer fast unsichtbaren Mini-Anzeige in Hertz. Wahrscheinlich muss man das Ding erstmal durch inapp Käufe zum Laufen bringen...?
3-4 Euro zum Fenster hinaus hmmm...

Nie wieder mit diesem Anbieter, für unsere anderen Instrumente werden wir uns andere Tuner kaufen.

**Developer response:** Hallo isjagut001, Violin Tuner Pro ist die einzige kostenpflichtige App, die NINE-Kalibrierungsvorgaben enthält: Französisches Barock, Barock, Wissenschaftlicher Ton, Standard-Konzertabstand, Sydney Symphony Orchestra, New Yorker Philharmoniker, Wiener Philharmoniker, Boston Philharmoniker und Chorton. Zusätzliche Funktionen wie Stimmgabel, Mikrofonempfindlichkeit oder benutzerdefinierte A4-Kalibrierung von 392Hz bis 466 Hz sind Teil der erweiterten Einstellungen und erfordern eine separate Zahlung (In-App-Kauf) ab EUR 2,29.

### 5/5 — 为什么要反复购买？

*2018-10-31*

买了提琴的一套，为什么小提琴专业版还要买？有有效期？

### 5/5 — 非常好的一款调音器

*2018-10-11*

非常好的一款调音器，是我用过最好的
