Personalized Cardio Made Simple.

Morpheus is the only system that gives you truly personalized cardio — dynamic heart rate zones, daily recovery scores, and weekly training targets that adapt to your body every single day. No more guessing how hard to train, which zone you should be in, or how much cardio you need each week.

Your Recovery. Your Zones. Your Targets.

When paired with the Morpheus M7 heart rate monitor, Morpheus measures your HRV and resting heart rate each morning to calculate your daily recovery score. From there, it sets personalized heart rate zones and weekly targets matched to your fitness level, your goal, and how your body is responding to training.

Unlike other apps that give everyone the same fixed zones based on percentages of max heart rate, Morpheus zones are anchored to your real physiological thresholds — the points at which your body shifts how it produces and uses energy. And because those thresholds change daily with your recovery, your zones adjust too.
This is especially important for training in your Zone 2 — the most talked about training zone in endurance and longevity research.

Zone 2 is most effective when you're training at the right intensity for your individual physiology. Too easy and you're leaving progress on the table. Too hard and you're no longer in Zone 2 at all.

Because Morpheus personalizes your Zone 2 range to your actual aerobic threshold — and adjusts it daily based on your recovery — you can be confident you're always training in the zone that delivers the most benefit, not just a static percentage of max heart rate that often misses the mark.

Please note: The Morpheus M7 heart rate monitor is required to unlock HRV measurement, recovery scoring, and personalized heart rate zones and targets.

Build Your VO2 Max. Improve Your Health. Live Longer.

VO2 max — your body's ability to use oxygen during exercise — is one of the strongest predictors of long term health and longevity. Research consistently shows that people with higher VO2 max live longer, healthier lives with a significantly lower risk of cardiovascular disease.

Morpheus is built around the training principles that drive VO2 max improvement most effectively. After analyzing data from more than 500,000 workouts and 1 million days of use, Morpheus has learned exactly how much time in each of its three heart rate zones drives the fastest improvements in aerobic fitness and conditioning.

Each week it sets a personalized target range for your low, moderate, and high intensity training — so you always know you’re giving your body what it needs and can recover from.
Meet your targets consistently and watch your VO2 max and fitness improve.
