### 2/5 — Приложение не работало

*2026-03-11, version 1.4*

Оплатила до версии pro и приложение не работает

### 5/5 — Everything I needed

*2026-02-21, version 1.4*

It does exactly what I need from it. Plays the note I’m trying to tune to or I play the note and it tells me how out of tune I am. This app is simple, which is perfect because that all I need/want it to be.

### 1/5 — Paid version doesn’t work

*2025-11-06, version 1.4*

It doesn’t work - paid for it and got none of the extras promised. No transposition. No additional colour. Doesn’t even tune - a scale flashes for a brief second and disappears or the app hangs.

App support doesn’t work. Just takes you to promote their other app Fretello. No way to contact the developer.

### 5/5 — 十分良いと思う

*2025-05-06, version 1.4*

シンプルだし使いやすいよ

### 3/5 — Good

*2024-02-27, version 1.4*

Can you add like not only see you like can you go back to the highest not like EBA?

### 3/5 — Not working on Apple Watch Ultra

*2023-12-31, version 1.4*

I downloaded it primarily for Watch usage. It can’t detect the audio even if the permissions are ok.

### 3/5 — перестал работать((

*2023-05-24, version 1.4*

все было супер, но почему то перестало работать

### 5/5 — Прекрасный тюнер

*2023-03-29, version 1.4*

Очень удобно что он хроматический, и нет ограничений по струнам, как в других приложениях, так как играя любую ноту, он сам определяет ее. Есть очень полезная функция, когда можно эту ноту воспроизвести и подбирать ее на слух. 
Спасибо за такое простое и удобное приложение

### 5/5 — Perfect

*2023-03-03, version 1.4*

This app is a perfect free easy tuner. I tune Saxophone with it

### 5/5 — The minimal user interface is definitely worth it by itself.

*2023-01-18, version 1.4*

It’s functions whilst looking absolutely splendid!
