Good Idea – Bad Implementation

It appears that this program has not been tested before the release.
I checked the Meditation Mode with Start Frequency of 18 Hz and Target - of 6.8 Hz, and here are the results:
For a 10 min session it worked as promised;
For 20 min and 30 min sessions, at the end of the session the frequency increased to 33.8 Hz (not to 18 Hz as it was supposed).
However, during a 60 min session, the frequency decreased to only about 15 Hz (instead of 6.8 Hz) during the first 10 min, but then it turned back and increased to …. 216 Hz!!!
They could bake our brains at 216 Hz! What else is wrong with this program?
