Zazen Journal
Meditation timer & journal
Free · Designed for iPhone. Not verified for macOS.
Time your sit, see your heart rate live, and keep a simple journal of every session.
Zazen Journal is a meditation timer for Apple Watch with a journal on iPhone.
Start a session from your wrist. Set a target length and the watch taps you when you reach it, so you can stop watching the clock and just sit. See your heart rate live during the session.
Afterwards, review every session on your iPhone: duration, average and peak heart rate, and your weight in kilograms or pounds. Sessions sync between your own iPhone and Apple Watch.
• Watch timer with a progress ring toward your target
• Target alerts with haptic taps
• Live heart rate, average and peak per session (requires Health permission)
• Weight logged per session, in kg or lb
• Simple controls: Double Tap, or the Action button on Apple Watch Ultra
• Session history and totals on iPhone
