Its a great app, but could use some improvements.

The quality of this application is good, but it could be much better. Instead of 16000 hertz, it should be 48000 hertz. This way, people can get extra clarity on their messages. 16,000 is good, but 48,000 is much better. Also, a few accessibility improvements could be made better.
