BurnCoach vs WeekFit

Real-time heart rate coaching for the most efficient fat-burning intensity: Zone 2. Your Apple Watch keeps you in the sweet spot — not too fast, not too slow — every second of your workout. Diet results come from intensity, not just time. ■ Why BurnCoach is different • Built for Zone 2 — Not just a heart rate display. BurnCoach tells you exactly how to adjust, every moment. • Voice + haptic coaching — Don't even look at your wrist. Cues drop into your music like Apple Maps navigation. • Auto phases — Warm-up, main, and cool-down transition automatically based on time and intensity. • Live glow ring — The ring color changes the instant you cross zones, glanceable on your wrist. ■ Core features • Real-time heart rate + zone detection (Rest, Warm-up, Fat Burn, Cardio, Peak, Max) • Automatic Zone-time and Fat Burn duration tracking • Post-workout report — zone distribution, average/max BPM, calories, GPS route (outdoor) • Two-way HealthKit sync — pulls in workouts from other apps and writes back yours • Live Activity / Dynamic Island — see your zone from the lock screen • Pace coaching — voice cues to slow down or speed up • Bluetooth heart rate monitors — pair a chest strap and train with iPhone only, no watch needed • Start from iPhone — remotely launch the watch workout, or start right on iPhone with your HRM ■ Why Zone 2 matters Zone 2 (60–70% of max heart rate) is where your body uses fat as the primary fuel. • Faster (Zone 3+): you burn more carbs, less fat efficiency. • Slower (Zone 1): not enough caloric demand to matter. If your goal is weight loss, time-in-Zone-2 is the most honest metric. ■ With or without a watch • Standalone Apple Watch — runs entirely on your watch; leave your iPhone at home. History syncs when reconnected. • No watch? — pair a Bluetooth heart rate monitor (chest strap) and get the same real-time zone coaching on iPhone alone. • Smart audio routing — coaching speaks through your earphones when connected, or your watch speaker when not. ■ Privacy first All workout data stays on your device. No external servers. HealthKit access is fully controlled by you. ■ Requirements • iPhone: iOS 17 or later • Apple Watch: watchOS 10 or later (optional — Series 4 and newer recommended) • Bluetooth heart rate monitor: standard heart rate profile devices (optional — for training without a watch) Make every 30 minutes count.
