Japanese Walk
IWT Timer + Real Watch App
Free · In‑App Purchases
Most walking apps just count steps. Japanese Walk trains you.
It's built entirely around Interval Walking Training (IWT) — the method that came out of research in Japan showing that alternating fast and slow walking paces improves fitness, blood pressure, and leg strength more than walking continuously at the same effort. No gym, no equipment, just a rhythm: walk fast, walk slow, repeat.
WHY THIS ISN'T JUST ANOTHER WALKING APP
Built for intervals, not steps. The whole app — timer, voice cues, stats, history — is designed around the fast/slow cycle, not bolted on as an afterthought.
A real Apple Watch app, not a remote. Start, pause, and track a walk right from your wrist, with live stats on your Lock Screen and in the Dynamic Island — see your current phase, countdown, and heart rate without unlocking your phone.
Heart rate zones that mean something. Pull heart rate from Apple Health or pair a Bluetooth chest strap, and see exactly how hard your fast intervals are actually pushing you.
Your route, your pace, your history. GPS tracking, distance, calories, and a full history of every walk — broken down by day, week, and month, with personal records that update as you improve.
No social feed. No leaderboard. No ads. Just your walk.
HOW IT WORKS
Set your interval length (3 minutes is the classic split — walk fast for 3, walk slow for 3, repeat), start the timer, and go. A voice cue tells you when to switch pace, so you never have to check your phone mid-stride. When you're done, see your full breakdown: time in each phase, heart rate trend, route map, distance, and calories.
WHY INTERVALS
Research on interval walking has found it can improve cardiovascular fitness, lower blood pressure, and build leg strength more effectively than walking at a single steady pace for the same amount of time — because the fast intervals push your heart rate up, and the slow intervals let you recover just enough to do it again. It's a small structural change to a walk you're already taking, with outsized results.
