Simple Zazen Timer
"Thank you for sharing with us, meditators, this timer. It is our company along the silent way."
"In a world of increasing complexity, simple is beautiful. With an elegant design and minimal user interface, this app captures just what meditation is about: calm, peace, mindfulness and self-awareness. Recommended for daily practice, or as a gentle reminder for any timed period of activity or rest, Simple Zazen Timer was a pleasure to find."
