### 1/5 — Permanently crashes

*2015-10-30, version 1.1.2*

The app crashes every time I try to perform a call. It used to be a great app, especially for frequent travelers. It reduced my roaming cost significantly. But now it does not even function.

### 1/5 — Error

*2015-10-03, version 1.1.2*

Error during registration

### 2/5 — პრობლემა

*2015-02-25, version 1.1.1*

დარეკვის დროს ითიშება თითონ პროგრამა (ქრაშავს)

### 2/5 — no push notifications

*2014-10-27, version 1.0.0*

Unless you make your push notifications work, this app is useless. Incoming call notifications are full of bugs, both, on passcode locked and unlocked phone. If these are fixed, there is a great potential for this app (in Georgia). Good start, but there is a long way to go yet. Very long.
