The words are effective, but the recording is amateurish to a distracting degree. One can hear the speakers salivatory noises quite consistently and he sounds--sorry--quite like a slobbering dog. It is quite a buzz-kill. He is continually swallowing saliva and making gross noises.
Another problem is the music that plays before and after cannot be disabled. It is too loud and it is not pleasant to have to reach for the phone to turn it off. Also, the vocal volume is too low.
If the recording had done professionally done on a technical level and if the speaker was a better broadcaster, I think the app would be strong. The music problem would have to be remedied as well.
