Designed specifically for the Japanese interval walking method (alternating fast and moderate walking paces), our app keeps you focused on your stride with clear audio cues, precise split metrics, and zero intrusive ads. WHY INTERVAL WALKING? Studies show that alternating between 3 minutes of brisk walking and 3 minutes of moderate walking yields superior fitness and blood pressure improvements compared to continuous steady walking.

Your workout data stays on your device and syncs securely via Apple Health. - Battery-Efficient Background Tracking: Track outdoor walks with low-power GPS and indoor treadmill sessions with step cadence. - Full Apple Health & Fitness Integration: Automatically writes workouts, active calories, and heart rate data to Apple Health.
