poor sound quality

I use this app with Iphone4S. The sound quality is very inconsistent. Sometimes, it is ok, sometimes, it is unusable and I have to scramble to find my phone. I don’t have the echo issue mentioned by others since I use the headset. The interface can be improved. The reconnect wizard is very annoying, if the same phone reconnects successfully, close the wizard! Also, a single click should bring up the menu, not double. Be consistent with the UI behavior of the rest of the system! I cannot recommend this app to others at this point but hope it can address some of these issues in future releases.
