About WALKY: Interval Walking
Make every walk count. WALKY makes "Interval Walking Training (IWT)" — the method developed by a Shinshu University research team in Japan — easy, cute, and effortless. Just alternate "3 minutes slow → 3 minutes fast," and the same amount of walking builds far more strength and cardio. ■ Why Interval Walking (IWT)? In a 5-month study, leg strength rose +13–17%, peak aerobic capacity +8–14%, with improved blood pressure. The goal: 60 minutes of fast walking a week (4 days is plenty). Short, hard, and effective. ■ Phone in your pocket — just walk Beat music and voice cues announce every phase change, so you never need to look at the screen. It buzzes to let you know even from your pocket or a locked screen. ■ Collect 14 cute Walkys Hit a goal and a new Walky character unlocks — your reason to take one more step today. ■ Your walks at a glance Route on a map, heart rate, segment-by-segment stats, calendar, and streaks — all automatic. Wear an Apple Watch for richer heart-rate data. ■ Free — no servers, no account, no login Everything is stored only on your phone. No sign-up; open it and start walking.
