### 1/5 — Does not work

*2025-06-19*

I purchased the app and it keeps telling me the octaves are locked. It also still shows ads, even though the ads are supposed to be removed. I contacted the developer and he kept telling me things to try to fix it and none of them worked. I do not recommend this app.

### 1/5 — No libera las octavas

*2025-05-07, version 2.6*

Compré la suscripción pero la app aún no libera las octavas.

Reinicié, reinstalé, cancelé y reactive la suscripción y nada. 😞

### 1/5 — Waste of time

*2025-04-26*

Not what I expected

### 3/5 — Tried

*2024-07-08*

Tried but app keeps closing. Report a problem sent me to an inexistent page.

### 2/5 — Non molto utile

*2024-03-17, version 2.5*

Tuner con molte funzionalità interessanti. Purtropp il giudizio non è positivo perché non è possibile bloccare la nota.

### 1/5 — So fake !!!!!😡😡

*2023-09-20, version 2.4*

I hate it😡it is broken if you get it
Don’t download this app or you get scammed

### 1/5 — Недоволен

*2023-08-29*

Заблокированные октавы, лол

### 1/5 — Приложение сырое

*2023-08-13*

Купил годовую подписку но приложение до сих пор показывает рекламу и октавы заблокированы. Так же само приложение показывает те ноты, которые ему, приложению, нравятся. В общем, в корзину, подписку аннулирую. Жалко потраченных денег

### 2/5 — 落ちる

*2023-01-28*

使っているとすぐ強制終了する

### 1/5 — Верните деньги

*2023-01-07*

Приложение битое. Через 15 секунд начинает скакать и лагать черти что. Не приобретайте. Лучше бесплатной пользуйтесь.
