Boring Cardio

Cardio is boring. That's the point. Boring Cardio is a treadmill companion that turns monotony into a feature. Pick a speed. Pick an incline. Walk for 30 minutes. Do it again. The app watches your heart rate and tells you what's actually happening inside your body — no badges, no streaks, no confetti. HOW IT WORKS Set your treadmill to the recommended speed and incline. Walk. When you're done, Boring Cardio pulls your heart rate data from Apple Health and shows you exactly where you landed: your average heart rate, your zone distribution, and how your body responded over time. Do a few sessions and patterns emerge. Your resting-to-active transition speed. Your cardiac drift rate. Whether that 6% incline is getting easier or you've been plateauing. The data is clean because the workout is controlled — same duration, same settings, pure signal. WHAT YOU GET (FREE) - Log treadmill workouts with speed and incline - View heart rate curves from your workout - See time-in-zone breakdowns (Zone 1–5) - Track workout history and consistency - Calibration walks to establish your baseline WHAT PREMIUM ADDS - Personalized workout recommendations that adapt to your fitness level - A physiological model that learns your unique heart rate response - Training goals with intelligent progression toward your target pace or incline - Advanced trend analysis: cardiac drift, heart rate recovery, aerobic efficiency - Choose your training style: climb (steep & slow), speed (brisk & moderate), or balanced THE PHILOSOPHY Most fitness apps fight boredom with gamification. Boring Cardio leans into it. The reward isn't a badge — it's watching your heart rate at the same settings drop by 5 bpm over a month. It's the quiet confidence of knowing your aerobic base is building, session by boring session. Built for people who just want to put in the work and see the trend line.
