## What is Boring Cardio?

Cardio is boring. That’s the point.

Boring Cardio is built for simple, repeatable treadmill walks. Set your speed and incline, walk for 30 minutes, then link the matching workout from Apple Health. You’ll see your heart-rate curve, time in each zone, and how your training changes over time.

No badges. No streaks. No confetti. Just a clearer view of the work.

HOW IT WORKS

1. Set your treadmill speed and incline.
2. Record a walking or running workout with something that saves heart-rate data to Apple Health.
3. Link the recorded workout in Boring Cardio.
4. Review your heart-rate curve, zone breakdown, and workout history.

PRIVATE BY DESIGN

There is no account to create. Boring Cardio has no ads or third-party analytics. Apple Health access is read-only and optional, and workout analysis happens on your device.

Boring Cardio is a general fitness tool, not a medical device. It does not monitor your heart rate in real time or provide medical advice.
