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. The Morpheus Methods - Train with Purpose Morpheus gives you 12 guided training methods to choose from, each designed to target a specific zone and training purpose — so you can get the most out of every workout. Whether you're focused on building your aerobic base with sustained low intensity work, developing your conditioning for a sport, or pushing your peak fitness with high intensity efforts, there's a method designed for exactly that. Each method gives you a clear structure with your heart rate guiding every phase. No guesswork, no confusion. Just targeted training that’s designed for your body so you can get the most out of every workout.

About

Replapse

Features
Read full description

Replapse is a workout tracker built around how you actually train, not how an app thinks you should. You decide what to track. For every exercise you pick the metrics that matter to you, whether that is weight and reps, hold time, rest, resistance band, angle, or the leg position on a front lever. If a metric is not useful to you, it is not on the screen. The result is a log that fits your training instead of forcing your training to fit the log. Log a full session the way it really happens. Mark warmups separately from working sets. Add drop sets and supersets to any set. Build circuits and run them for as many rounds as you want. Put a warmup section before your main work. Save your own workout templates, or start from an empty one and add exercises as you go. It works for the gym and for calisthenics in the same place. Track barbell and dumbbell lifts, and bodyweight work like pull ups, dips, handstands and front levers, without switching apps. Recovery matters as much as the training itself, so Replapse also tracks HRV. Take a reading and watch the trend over time so you have a real sense of how rested you are before a hard session. You can log your bodyweight too, which means your strength, your recovery and your weight all sit in one profile instead of three separate apps. HRV readings are taken with a Bluetooth heart rate monitor, like a Polar H10, a Garmin or Wahoo strap, or any standard Bluetooth chest strap. Pair one, take a reading, and your recovery data sits next to the rest of your training. Everything stays on your device. No account, no sign up, no cloud. Your training is yours and it never leaves your phone. Create a profile in a few seconds and start logging straight away. If other people share your device, add a profile for each of them and keep everyone's history separate. Replapse is for people who want a complete picture of their training and the freedom to track it their own way. What you can do: Pick your own metrics for every exercise Log warmups, working sets, drop sets and supersets Build circuits with multiple rounds Create warmup sections and your own templates Track gym and calisthenics side by side Record HRV and follow your recovery over time Log bodyweight and watch it change Measure HRV with a Bluetooth heart rate monitor Keep multiple profiles on one device Use it fully offline with no account
