DaInterval Pro – Zone 2 Intervals

Zone 2 intervals and heart rate zone training — with alerts that let you stop staring at your watch. DaInterval runs interval workouts locked to your target heart rate range, so you build your aerobic base without drifting into junk-mile intensity. WHY ZONE 2 Zone 2 is the easy-feeling effort that builds mitochondria, fat-burning capacity and a bulletproof aerobic base — the single highest-return cardio zone, especially after 40. The hard part is staying in it. DaInterval handles that for you. FEATURES - Interval running and walking guided by your custom heart rate range - Alerts when you drift above or below your target zone - Simple, readable in-workout screen: current HR, zone status, interval time - Free, no account, no ads Run easy. Get faster. Work with your body, not against it. Want haptic zone alerts and detailed pre/post-workout stats? Upgrade to DaInterval Pro.
