This app doesn’t include any audible alarms.
There's supposed to be an audible alert for the one-minute-warning, but it has never worked.
To me it’s worthless without one - akin to using an alarm clock with no alarm. It’s like waking up 3 hours late and seeing "WAKE UP!" on the clock’s display.
I’ve already turned hard-boiled eggs into VERY hard-boiled eggs because I was expecting to hear an alarm and wasn’t sitting at the computer waiting for a VISUAL notification.
