Mac only. Sorry. 🙂
My good friend Tripp Lanier created a meditation timer widget. It’s works for more than just meditation too. For example, if you’re a musician and you want to ear train or write music for 30 minutes, your music sessions will begin and end with a nice bell sound. There’s even a delay to allow you to get ready before the timer begins.
I’m trying to help him reach the top 10 so if you could go here and download his widget, I’d consider it a personal favor.
