Best wearable out there.
Best wearable on the market if you are serious about your fitness.
Excellent!
Excellent training and recovery tool. It has helped me tremendously.
Great
Wish I could press one less button to check recovery
Best wearable
I have to pick one gadget from all the wearables I have tried it would be Morpheus! It’s reliable, easy to use and helped me with improving my cardio. The costumer service is absolutely fantastic as well.
The best wearable tech I own
I’ve never worn anything that gave me as specific data as Morpheus. My training is precise and my HRV is rising!!!
UI could be improved
The device is great and I love the metrics. However the UI could be improved. It takes 4 or 5 steps and confirmation to start a recording a workout. It should be faster and easier. Multiple times, I ended up realizing the workout didn’t start because there is a last confirmation. If I start a workout, why do I need to confirm so many times. Let’s just start recording!

70 year old
Before Morpheus, my aerobic training was basically a guessing game — my HIIT sessions left me wiped out with no real sense I was getting stronger. Getting a VO2 Max test and pairing it with Morpheus changed everything. Now it feels like I've got a personal coach walking me through every single workout, dialing in exactly what my body needs that day. That guidance paid off in a big way this summer when I completed a 40-mile hut-to-hut trek on Iceland's Laugavegur Trail — I honestly don't think I'd have had the engine for it without Morpheus behind me. I'm already counting down to my next VO2 Max test to see how far I've come!

Great program
Easy to use program to assist you with increasing your heart health. Highly recommend.
Only HRV app you need
I’ve been with Morpheus since day 1. If you care about quantifying HRV and actions you can take to improve this is the app for you
Morpheus Review - Kelly Amidon Master Fitness Professional
I started using Morpheus in October 2025. I’m 58, I’ve trained seriously for 40+ years, and I already thought I understood recovery. I didn’t.
The morning readiness score and HRV number gave me something I’d never had: an objective reason to turn the volume or intensity down before I felt wrecked. On low-score days I still train, but I follow the app instead of my ego. On high-score days I can push. That single change has been the biggest upgrade to my training in years.
In ten months my HRV has moved from the mid-60s into the mid-70s (typically 72–74). Resting heart rate is trending down. I feel the difference in how I recover between sessions and how consistently I can train.
I use Morpheus as my primary recovery and zone tool and still wear an Oura ring for sleep context. The two together are useful, but Morpheus is the one that actually changes what I do in the gym that day.
I’m a coach. I now talk about readiness the same way I talk about load and protein. That’s how much it has changed my own practice.
If you train hard and you’re not measuring recovery, you’re guessing. Morpheus took the guesswork out for me.

Best Recovery Status and Cardio Training Around
I’ve been using Morpheus for several years now. Before Morpheus, I used Garmin, Oura ring and Apple Watch. I’ve tried a lot of different things. They all have their place and certainly helped out a lot but once I started following the method laid out by Morpheus, my cardiovascular training, which had plateaued for a while, started to accelerate rapidly. I definitely found my recoverability improving, and my stamina during strength workouts in addition to my cardiovascular training improving significantly. Highly recommend for anyone serious about their health and performance.

Game changer
The best fitness accessory you can get.
Best recovery data!
I love using Morpheus every day to see how recovered I actually am! It gives me invaluable data to know if my exercise plan is actually working and if I can handle (and recover from) my workout plan. I think the data Morpheus gives is way more valuable than other wearables because it measures recover in the morning after a recovery cycle NOT during night!

I have been using Morpheus for years and it’s really helping me improve my v02max I’m almost 90% percentile for my age
Recovery was key
For years, I worked out hard and consistently and couldn’t understand why my resting heart rate wasn’t dropping. Once Morpheus started to help me understand recovery, I’ve finally been able to see my resting heart rate drop over time.
Most important device I own
The morpheus is easily the most important device I have in capturing my heart rate data (and overall health). I use it religiously every morning to get my recovery score and HRV. It acts as a guide to help me determine what level of effort is needed each week. I recommend the morpheus to all my clients and they too are finding it immensely valuable.

Great fitness tool
This the single most useful tool you can use on your fitness journey. It’s much more useful than a smartwatch but you have to learn how to use it for best results.
Zone two calculation
This app is the best of the three I use to calculate hrv and is the only app I am aware of that provides a daily zone two range based on multiple variables including hrv.
Great Tool
Been using this HR measurement tool since it was introduced. Accurately records HRV and training stress. Customized training plans work well to progress my fitness level. I use it daily to measure recovery during all types of training. The UI and visuals are great. Works perfectly every time. Sensitive enough to pick up the off days and sick days too. I highly recommend it.

My new favorite piece of tech as a Sports Performance Coach
I rarely write reviews for things because I have to honestly be impressed to take the time out of an incredibly busy schedule to write one. I have been coaching for almost 30 years. The last decade has been primarily in sports performance and significantly skewed toward track and field and endurance athletes. I consider myself an athlete myself and use as much technology as I can to manage recovery and push performance. I was already a believer in HRV as a tool to track recovery and readiness to train. But I am honestly pretty shocked at how this app lines up with other tests that I’ve done on myself and also how closely it lines up with how recovered I should be after certain types of workouts.
I recently have been engaged in a very structured training plan for endurance running that includes high amounts of zone 1 and zone 2 training plus lactate threshold work once per week. No dedicated VO2Max just simply bleed over VO2 max here and there in the early stages of my programming. The last version of the app did not clearly define zone 2 but I knew enough where it should’ve landed. I really wanted to define my zones tightly so I had another Coach that I work with perform a lactate threshold test on the treadmill for me to get my precise zones. I was surprised to see Morpheus and the LT test lineup within two BPM for the prescribed zones between Morpheus and my LT test. Really the only driver that changed the range was the percent of recovery day by day, which is expected. The part that really shocked me is I ran six four week mesocycles with a deload between them with very precise and controlled progressive overloading focusing on the correct proportions of recovery wok, Zone 2 and LT with bleedover VO2Max work. My intention was to pull my aerobic threshold ceiling to the right by developing my lactate threshold energy system significantly. My second lactate threshold test after those six cycles changed my ceiling on my aerobic threshold by 18 BPM. I radically shifted my aerobic threshold and lactate threshold to the right allowing me faster paces while staying in my new zone thresholds. I expected Morpheus to lag and be inaccurate after this. I started running at my new paces and within one week Morpheus had completely adjusted t’s zone limits to match my LT test. I did not feed that data to it so I’m not quite sure what the algorithm is looking at to make those adjustments but incredible! Then the next version of the app came out with zone 2 clearly defined and again it matched what my LT test showed within a few BPM.
Finally, I have one more mesocycle to run in my current phase of training and then it will be time to retest LT. I have noticed in the last two weeks that Morpheus is adjusting the volume range up while increasing the intensity (min/max BPM per zone). It thinks I can handle more time and higher intensity in each zone. I’m trusting the process at this point (which is hard for me) and I am wildly interested to see in my next LT test if it lines up with what Morpheus is suggesting. If it does, I’m going start pushing this to all of my athletes. Right now I can say I am solidly a believer, and after my next LT test, I might just be sold for life.
