WalkWith: Zen brings three ancient Japanese walking traditions to your daily life — each a different way of meeting the world on foot. KINHIN · 経行 Zen Walking Meditation. One breath, one step. Developed in Japanese Zen monasteries since the 13th century, kinhin transforms movement into meditation. WalkWith: Zen guides each session with a breathing pacer, synthesized temple bells, and a single mindfulness prompt — inviting you to walk without arriving anywhere. SHINRIN-YOKU · 森林浴 Forest Bathing. Proven by decades of Japanese research to lower cortisol, reduce blood pressure, and boost immune function. The app opens with a bell and gentle guidance, then steps aside so the forest can do its work. Ambient soundscapes — synthesized forest, wind, or rain — accompany you if you need them. SANPO · æ•£æ© Purposeless Walking. The Japanese art of the unhurried stroll — nowhere to be, nothing to achieve. Gentle prompts keep you curious and present without pulling you out of the moment. KAIZEN WALK · é–“æ© Interval Walking Training. Alternate 3 minutes brisk with 3 minutes easy across 3–8 rounds. Based on the Shinshu University IWT protocol — the most clinically-validated walking intervention in Japan — Kaizen Walk builds aerobic fitness gently and sustainably. Your Apple Watch guides each phase with haptics and live heart rate. —— WHAT GROWS AS YOU WALK A karesansui dry garden evolves through nine stages as you build your practice. The 72 Japanese solar micro-seasons mark time on your home screen. Streak milestones celebrate 7, 21, 30, 60, and 100 days of consistent practice. TRULY AMBIENT AUDIO All sounds are synthesized in real time — singing bowls, forest soundscapes, and breath-cue tones — with no pre-recorded audio files. Bell strikes gently duck other audio and restore it when they fade. APPLE WATCH COMPANION Walk completely phone-free. Breathing pacer with haptics for Kinhin. Phase transitions, heart rate, and Hard/Easy intensity feedback for Kaizen Walk. Sessions sync automatically to iPhone when you're done. HEALTHKIT INTEGRATION Workouts saved automatically. Mindful minutes logged for Kinhin and Shinrin-yoku. Step counts and distances tracked for every mode. ADAPTIVE COACHING Kaizen Walk learns from your sessions. It reads your energy ratings, Watch intensity feedback, and round completion to suggest when you're ready for more challenge. A coach, not just a timer. YOUR DATA, YOUR DEVICE No account required. All session data lives on your device. Lock Screen widgets, Dynamic Island updates, and Home Screen widgets keep your practice visible throughout the day. —— WalkWith: Zen is the first app in the MoveWith family — a collection of programs built on one belief: movement is a practice, not a metric.
