Lotus is an unobtrusive timer designed specifically for meditation.
Lotus provides a 3-phased timer routine that can be completely customized. It was designed specifically for meditation but can be used for anything.
Lotus includes a dozen high quality sound effects you can use, or you can select your own sound files or MP3s to play as the various phases of your routine start or end.
Lotus 2.0 includes a no-sleep mode to ensure your mac doesn't fall asleep while your timers are running.
