Doesn’t work

Great idea but app doesn’t work. No one to contact for help/support (at least that I can see). Had to pay just to download app; no trial or even limited access to features to first try it out.

Self directed speech therapy

I was looking for a tool that would help me correct my overly centralized vowels. This app provides the same feedback as a speech therapist, but at a fraction of the cost.

It works but why does it skip 3khz on the scale at the bottom?

Trash

This app simply doesn't work. I was hoping for something like praat. This is just a hot mess and a waste of money. I hope they debug or whatever they need to do to get this app working...
