Kadenza Burn

One thing, done well. Kadenza keeps your workout at the right pace, right on your Apple Watch. No account, no ads, no distraction.

Kadenza is a workout app focused on one thing: keeping you in the right heart rate zone to burn fat, improve your conditioning, and train smarter.

Most apps overwhelm you with metrics and charts. Kadenza keeps it simple. It shows where you are, tells you when you drift out, and tracks how long you spent in the right place.

HOW IT WORKS

Kadenza calculates your ideal training zone using Apple Health data. During exercise, your Apple Watch reads your BPM in real time and shows which zone you're in: WARMUP, KADENZA, CARDIO or PEAK.

The KADENZA zone is the one that matters. It's where your body burns fat and builds aerobic capacity without leaving you wrecked for days. Spending 30 to 60 minutes there, 3 to 4 times a week, is what physiology research points to as the sweet spot for cardiovascular health and longevity.
