Confusing/incomplete instructions – Entrain Review

I believe an app like this needs to "talk to a common person" to have any value. It fails miserably at that. It doesn't explain things in common language, uses arbitrary and confusing terms and as such, stops short of explaining what exactly am I supposed to do, sit in the dark, sleep, wake up at odd times...? Nice gimmick but I see no use value for a common person. Deleted, not looking back. Plus, it's abandonware.
