Volume Too Low

I bought this because I wanted to be able to communicate with my wife without using the phone feature of our respective iPhones when were in the same supermarket or same floor of a department store for example. Unfortunately, though this app is very simple to use, the volume is just too low for anyone to hear anything especially in a public place like a supermarket. This despite the fact that both my wifes iPhone and mine had their volume turned up to maximum! This app wouldve been nicer if the developer fix the volume problem. In the meantime, I wouldnt recommend this app for anyone.
