### 4/5 — Van Tri Tran

*2015-12-16, version 2.3.1*

Ứng dụng rất hay và hữu ích. Nhưng nó sẽ còn tốt hơn nữa nếu hỗ trợ tính năng Slide Over của iOS 9.

### 2/5 — I had thought it was good :(

*2015-11-18, version 2.3*

The recent update is too bad. Bugging fixes but there are still many fixes and after the last update (18/11/2015), i can't open this app :((((. In my opinion, this app don't need more update, i don't like that changes

### 1/5 — Crash
