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 · 散歩 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 · 間歩 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.

Most calorie trackers hold you to a strict daily limit. Cal/d tracks your daily average instead, so one heavy day doesn't wreck your progress. Set a start date and daily limit, and Cal/d reads dietary energy from Apple Health to show: - Score: a 0–100 read on how today is going, from your pace, room left and daily average. - Daily Average: total calories since your start date, divided by days elapsed. - Remaining Calories: stay under your limit and you build a surplus to spend whenever you want. - Surplus Goal: surplus divided by daily limit is how many days you've saved. Set a target (say, 3 days). - Countdown to Next 250: a timer until your next 250 calories, expandable to 5 timers ahead (20 with Plus). Don't want to wait? Factor in Active Energy too. A jog raises your surplus and moves you closer to your goal. Log calories and nutrition directly in Cal/d, or keep your current tracker and open it with one tap from a built-in link list. Anything that writes to Apple Health, Cal/d can read. On Apple Watch, turn the Digital Crown through your Score, budget, pace, average, goal, and countdowns, and add complications to your watch face. PLUS FEATURES: - Unlimited What-If calorie planning - Unlimited surplus-goal days - All 20 countdown milestones - Custom Chart date ranges longer than 30 days - "Last…" Chart periods beyond the last 7 days - Score breakdown - After-exercise pace comparison - Live Activity on the Lock Screen and Dynamic Island - Calorie checkpoint notifications Cal/d is not medical advice. Consult your doctor before changing your diet.

Verdict
