Interval Timer

Build your own run/walk workouts in seconds. Three sections, custom paces, voice cues, and live distance estimates. Made for Couch-to-20K and everyday runners. Running Walking Practices is the interval timer that gets out of your way. Whether you're starting your first 5K plan, training for a half marathon, or keeping your weekly mileage steady — design a workout once and let the app handle the rest. HOW IT WORKS • Tell the app your running pace and walking pace (in min/km). • Build a workout with three sections: Warm Up, Main, and Cool Down. • Each section has its own number of sets, run period, and walk period. • The app estimates total distance from your paces in real time. • Hit Play. The timer guides you through every interval. FEATURES • Three configurable sections: warm up, main, cool down • Per-section sets, run duration, and walk duration • Walk-only sections (great for cool downs and recovery) • Live distance estimates based on your custom run and walk paces • Four sound styles to choose from: – Beep — sharp synthesized tones – Chime — softer, gentler tones – Voice — spoken countdowns and section names – Off — silent (haptics only) • 3, 5, or 10-second pre-period countdown • Distinct slow-down tone before every break • Background-aware — the timer stays accurate when your phone is locked • Light, dark, and system theme • Adjustable text size (Small / Default / Large / XL) • Haptic feedback on every transition • Quick edit any practice with a swipe gesture • Color-coded sections at a glance: orange warm up, green main, teal cool down PERFECT FOR • Couch-to-5K and run/walk training plans • Half marathon and 10K race preparation • Recovery runs that mix gentle jogging and walking • Beginners who don't yet run continuously • Anyone who wants workout structure on autopilot PRIVACY-FIRST Everything stays on your device. No accounts, no data sync, no analytics, no ads, no tracking. Your practices live in your phone's local storage and nowhere else. The app declares its only data API (UserDefaults, used to remember your settings) in its privacy manifest. WHY ANOTHER INTERVAL TIMER? Most interval timer apps drown you in modes, premium tiers, and features you didn't ask for. Running Walking Practices stays focused: open the app, tap the practice you want, hit play. That's the entire flow. No upsells. No "share to unlock." No begging for ratings. Designed for iPhone and iPad. Light and dark mode supported. Dynamic Type aware so everything stays readable at the text size you prefer. Build a workout. Hit play. Run.
