### 5/5 — Easy to look on iPad

*2025-07-11*

This tuner is really good at its visual expression. If you can test your violin, it displays how the harmonic of the violin.

### 4/5 — Helpful but needs some improvement

*2023-08-25*

I really like this program overall.  The difficulty I experience is that there seems to be a lag time between the time I tune and the time it registers on the screen.  This makes it difficult to know when I’ve actually tuned it properly and frequently I have to retune because the pitch is now too sharp.  Also it could “listen” to the pitch a little longer.

**Developer response:** You can try changing the Tuner Sensibility settings from the main settings menu and moving the microphone closer to the instrument. We are aware of this and we will consider it for future updates of the app. Thanks for your much appreciated feedback.

### 5/5 — Violoncelle

*2021-12-11*

Trop facile !

### 5/5 — Well worth the price

*2021-07-06, version 3.0.11*

Accurate easy-to-read tuning even when there's background noise. I spent a long time looking for the perfect tuner and am happy with this one.

Request: Please make the app remember the view that was chosen the last time the app was used. Or provide an option to select a default view.

### 5/5 — Essential FFT

*2021-01-31*

Not so much as a tuner, (which is fine), but for the excellent FFT! This is the best FFT for general use on iOS. I teach acoustics and I use this FFT for live demonstrations of the analysis of sound. The FFT graph is smooth and easy to use. “Seeing” noise, or the harmonic series of instruments is great regardless if you’re using an iPhone or an iPad Pro. Due to the high resolution of the iPad Pro display, screen captures as videos are high resolution too.

If you’re looking for a simple FFT that looks great, download the free version and give it a shot.

### 1/5 — 환불 요청합니다.

*2021-01-28*

헤르츠가 정확도가 떨어지는것 같아요
구분이 가지 않아서 환불 요청합니다.

**Developer response:** 불편을 끼쳐드려 정말 죄송합니다. 이미 지원팀(support@ntrack.com)에 도움을 요청해 보셨나요? 기꺼이 해결책을 제시하거나 구매 금액을 환불해 드리겠습니다. 우리는 귀하의 이메일을 찾을 것입니다.

### 1/5 — 結局

### 5/5 — Tuning

*2019-02-20*

I use this app to tune my viola and it works great. There are many different visual options for when you tune. I compared my viola to my piano (which is tuned) and it was on POINT!!!!

### 5/5 — 素晴らしい

*2019-01-09*

チューナーを鳴らす場合、ロック状態で鳴らしてほしい 
あとは、バックグラウンド機能もほしい
