not good at all

I dont understand if this application was developed in 1 night. usually when I play I lose the game "on time" when my opponent time is 0 seconds. even if I play my move in advance it takes 3 seconds to do it. the same thing happens when I play in 3G,4G or WiFi. when I play on my PC on the same WiFi everything goes better. Im very disappointed and this application is a big "bug". Shame.
In facts, if you have a lot of time but the opponent will make the move when his time came to 0 seconds, the connection for the game is closed. For the server your time continue to go on(but you cant see that, because the developer cut the connection) and youll lose at the end of your time. Really pity, to not fix an error like that on a chess program.
