Interval walking is the scientifically proven, low-impact method to boost cardiovascular health, burn calories, and build endurance without stressing your joints. Interval Walking - Splits provides the cleanest, distraction-free interval coaching experience on iOS. 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. KEY FEATURES - Audio Coaching & Haptic Wrist Alerts: Gentle audio chimes and watch vibrations prompt you the exact second to accelerate and recover without looking at your screen. - Standalone Apple Watch App: Feel every phase transition on your wrist with haptic feedback, live pace, heart rate, and split metrics—no phone needed. - Custom Interval Programs: Set custom walk/rest durations, split targets, and warm-up/cool-down periods in seconds. - Offline & Private: No mandatory account creation, no tracking, and no cloud requirement. 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. NO SUBSCRIPTION TRAPS Unlike bloated fitness apps with confusing paywalls and full-screen mid-workout ads, Interval Walking - Splits gives you a reliable, ad-free training companion built for daily consistency. Start your fast-and-slow interval walking routine today and experience the difference in every step!
