Features & Capabilities

Zone 2 app tracks how much of your weekly workout time is spent in the zone 2 heart rate range (typically 60-70% of max). Aiming for 150 minutes or more of weekly exercise in zone 2 is recommended to optimize endurance, fat burning, and balanced training. It supports Apple Watch for live zones with haptic feedback and Siri announcements, and can connect to Bluetooth heart rate monitors for live reporting when Apple Watch isn't available. Zone 2 uses all workouts saved to your device with heart rate data to calculate weekly zone minutes.

Zone 2 features include weekly, daily, and monthly zone tracking with goal-based charts; Strava uploads; Home Screen and Lock Screen widgets; live zone reporting during workouts; an Apple Watch app with live total calculations and optional haptic feedback and alerts; iPhone mirroring; zone goal or open goal modes; a heart rate zone calculator; and live activities on Dynamic Island or Lock Screen.

I am new to Zone 2 training for Weight Loss but I am finding the app very beneficial. It’s hard for me to log into Zone 2 on a elliptical machine. Some sort of graph that tracks. My history might help me hit this sound better, but this product is pushing me in the right direction.

This app does exactly what I need! Shows you what zone you are in during a workout, tracks cumulative time in your species zone (2 for me), and tracks weekly time in zone. I am aiming for 150 minutes and this app keeps me on track
