About this sound
Referee whistle is in the loud, for heavy sleepers group: for heavy sleepers: harsh, high-energy sounds that are impossible to sleep through, best combined with the sums-to-stop option. Pair it with the fade-in switched off and the sums-to-stop mission for the heaviest sleepers. Set the volume with Test sound before you sleep; the alarm rings at the volume your device is set to.
Every alarm can have its own sound, so you can wake to referee whistle on weekdays and something gentler at the weekend. If you cannot decide, choose Surprise me and the clock picks a different sound from the 60 each time.
