### 1/5 — Will mein Geld zurück

*2021-07-02*

Also entweder bin ich zu Blöd oder ...  
besser Oder.

### 1/5 — Pessima

*2020-08-20*

Ho qui stato l’app a pagamento ma se rivelata inutile per l’accordatura del pianoforte sconsiglio. Quando incominciano ad alzarsi o abbassarsi le frequenze non le percepisce e non è l’apparecchio telefonico che non funziona perché ne ho acquistata un’altra analoga che però funziona perfettamente

**Developer response:** Mi dispiace, non so quale problema abbia incontrato. La nostra nuova versione ha raggiunto una maggiore precisione di misura.

### 3/5 — Добавьте поддержку спящего режима!

*2020-06-21*

В описании сказано, что приложение интуитивно понятно, однако это не совсем так. Пришлось повозиться некоторое время, чтобы разобраться с функциями. Главным недостатком приложения является то, что оно постоянно вылетает, как только гаснет экран телефона. После этого все то на чем остановился приходится выбирать сначала, жутко бесит. Приходится постоянно тыкать в экран, чтобы оно не уснуло.

**Developer response:** Спасибо за отзыв. Проблема будет исправлена ​​в следующей версии.
