Hey, neat app. I just want to warn you about claims like it significantly improves fluency when using it. This definitely isnt the case for everyone. I used both the fluency master and the speakeasy and after the novelty of it wore off, so did the fluency. Also, am i correct in understanding you'll need to have an earbud in and have a microphone somewhere (likely on your earphone wire) for this to work, right? That said, it sounds like an innovative use of technology and certainly much cheaper than the more traditional DAF devices I mentioned.
