Good app with some flaws
I enjoy using this app, but if you shorten the recovery time (as I work at a slightly faster pace), the music becomes out of sync. Sometimes the app will start talking, even when it is not selected. I am not sure if it is because I am using a beta iOS, but it was fine until last update...
