### 1/5 — Rubish,Only stollen your money.垃圾软件，骗我12块钱

*2019-09-23*

垃圾软件，没有任何实用功能，骗钱的

### 2/5 — Сделайте нормальные кнопки!

*2018-07-25*

Все хорошо, не тупит и не лажает. Но по кнопкам не попасть! Сделайте три ряда, с кнопками побольше! Иначе приложение теряет смысл. Спасибо!

**Developer response:** The app is the treble-side of 5 row B-system CBA as listed in the app description. No idea what you expected.

### 2/5 — Basic

*2018-04-21*

This is a basic fingering layout app to show you the right hand notes on a bayan (Russian) accordion.  There are no tutorials or exercises.

### 5/5 — Октавы

*2017-02-25*

Приложение отличное, но было бы лучше, если была бы возможность смены октавы (пролистывания клавиатуры вверх и вниз), а то не всегда хватает стандартного положения.

### 5/5 — iPhone 6+

*2016-10-04*

Вроде пока четко. Ещё бы добавить возможность регулировать размер кнопок и добавить бас.
