The world of fitness trackers used to be simple: you bought a watch, it counted your steps, your health and your fitness. But then WHOOP came along and changed the game by removing the screen and focusing entirely on the data that happens while you’re not looking at your wrist.
I’ve been a long-time WHOOP user and I have recently spent several months switching between the WHOOP 5.0 vs WHOOP MG to see if the Medical Grade label is actually worth it or not.
If you’re like me, who probably cares more about the insights than the hardware itself, you need to keep in mind that there is a massive gap in how these two devices treat your health data. After living with both, I’ve realised that while they look almost identical on your wrist, they are built for two very different types of people.

The Key Difference: What Is WHOOP MG?
This is the question I get asked most often: Is the MG just a 5.0 with a different name? Not exactly. While the WHOOP 5.0 is the natural evolution of the performance tracker we’ve always loved, the WHOOP MG (Medical Grade) is WHOOP’s first real move into the clinical world.
Both devices share the same ultra-efficient processor and that’s game-changing, but the WHOOP MG version is equipped with a specialised conductive metal clasp that acts as a physical bridge between your body and the sensor.
By simply touching this clasp with your opposite hand, you can take an on-demand, medical-grade ECG (Electrocardiogram). It’s an FDA-cleared system designed to detect early warning signs of Atrial Fibrillation (AFib), making it much more than just a fitness coach.
When I first switched to the MG, it stopped feeling like a standard wearable and started feeling like a heart screener on my wrist. Having that clinical accuracy tucked away in a tiny, screenless strap gave me peace of mind that honestly changed how I approached my recovery days.
Design and Hardware
When I first unboxed the WHOOP MG, I actually had to double-check which was which. If you put them side-by-side, they look like identical twins. Both the WHOOP 5.0 and the WHOOP MG are about 7% smaller than the old WHOOP 4.0.
It doesn’t sound like much on paper, but on the wrist, it feels much more flush. They’ve managed to pack a 60% faster processor into a frame that’s only about 34.7mm long and 10.6mm thick.
One thing I noticed immediately is the weight. The WHOOP 5.0 is a featherlight 26.5 g, while the WHOOP MG is just a hair heavier at 27.3g. That tiny bit of extra weight in the MG comes from the specialised hardware needed for heart screening. You truly forget you’re wearing them, which has always been my favourite part of the WHOOP experience.
The WHOOP 5.0 usually comes in a clean, matte finish that doesn’t scream for attention. Whereas WHOOP MG, on the other hand, feels a bit more premium. It features a Luxe metal clasp and a slightly shinier sensor casing. But those metal parts aren’t just for show, they are the actual ECG-ready contact pads. To take a reading, you just touch the indents on the clasp.
The real hero of the hardware update is the battery. Moving from the WHOOP 4.0’s 5-day limit to a 14+ day battery life felt like absolute magic. I recently wore the MG for a two-week trip to the mountains and didn’t even pack a charger. The new internal architecture is 10 times more power efficient, which is how they pulled off this extra week of life without making the device bulky.
And let’s talk about the charging, it’s still the best in the game. Both models use the same Wireless PowerPack, which is now IP68 waterproof. This means you can slide the battery pack onto your wrist and hop right into the shower or a pool.
Health Features Comparison
This is where things get interesting and, honestly, a bit more personal. If your main goal is just to see how hard you pushed during a morning run or a gym session, the WHOOP 5.0 has everything you need.
But for me, the WHOOP MG changed the whole vibe of the device. It moves the conversation away from just fitness and into longevity. If you’ve ever worried about your heart health or just want the most complete picture of what’s happening inside your body, the WHOOP MG is the one that really digs deep.
Heart Rate & Sleep
Both devices use the same upgraded sensor array that captures data 26 times per second. My sleep stages (REM, Deep, Light) were identical on both devices and the accuracy during high-intensity intervals was significantly better than the old WHOOP 4.0. Whether I was doing a heavy lifting session or just sleeping off a long day, the core data felt rock solid on both.
ECG
On the WHOOP MG, you have a feature called Heart Screener. Whenever I felt a bit off or had too much caffeine, I’d hold the metal clasp for 30 seconds. The app then generates a medical-grade report that can detect signs of AFib (Atrial Fibrillation).
I actually showed one of these reports to a doctor friend and he was genuinely impressed by how clear the reading was. It’s like having a mini-clinic on your wrist.
Blood Pressure Insights
The MG also offers Blood Pressure Insights, something not available on the WHOOP 5.0 and is a total game-changer. It requires a one-time calibration with a traditional arm cuff and then it uses your heart rate and blood flow patterns while you sleep to estimate your BP each morning.
I found it incredibly useful for seeing how a stressful workday or a salty late-night pizza affected my numbers the next morning. It’s still in Beta, but the trends it showed me were eye-opening.
Healthspan & Biological Age
One feature I absolutely love on both devices is Healthspan. It looks at nine different metrics, like your HRV and resting heart rate, to calculate your WHOOP Age.
It’s a bit of a reality check to see if your body is technically older or younger than you actually are. Both bands give you this biological age, but the WHOOP MG’s extra heart data makes the longevity coaching feel even more tailored to your actual health risks.
Stress Monitor & Daily Coaching
Both the WHOOP 5.0 and WHOOP MG have the Real-Time Stress Monitor, which I check constantly. It shows your stress levels on a scale of 0 to 3 throughout the day. If I’m in a high-pressure meeting, I can see my stress spike in real-time.
The app then gives me Stress Breaths, simple breathing exercises to help me calm down. It’s a small touch, but it really helps me stay mindful during a chaotic day.
Recovery and Activity Tracking
Whether you choose the WHOOP 5.0 or the WHOOP MG, the Strain and Recovery experience remains the same at its core. I took both of these on a 10km trail run and the calorie burn and strain scores were virtually indistinguishable.
This is because both devices use the same upgraded sensor array that samples your data 26 times per second.
One of the coolest updates I noticed is Passive Muscular Load (MSK). Previously, if I performed an intense workout on leg day but didn’t actually start the workout within the app, my WHOOP would only see my heart rate. Since lifting doesn’t always send your heart rate as high as a sprint, I’d finish a brutal session with a tiny strain score.
Now, both the WHOOP 5.0 and WHOOP MG use their built-in sensors to feel the intensity of your movements. It recognises the difference between a casual walk and a heavy set of squats, automatically giving you credit for the physical stress on your muscles even if your heart hasn’t caught up yet.
Both models feature the Strength Trainer, which I use to track my lifting sessions. By logging your specific exercises and weights, the app calculates your Muscular Strain with incredible precision.
It understands that a heavy deadlift puts a different type of stress on your body than a bicep curl. I actually started seeing my Sleep Need increase on heavy lifting days. It feels like having a coach who knows exactly how beat up your body is, not just your cardio system.
The Recovery Score (the famous Red, Yellow and Green circle) is calculated identically on both. It looks at your Heart Rate Variability (HRV), resting heart rate and sleep quality from the night before.
In my testing, if I had a late-night pizza or an extra coffee, both bands caught it immediately the next morning. The personal touch here is that WHOOP learns your specific baseline. It doesn’t compare you to a pro athlete, it compares you to you. This makes the daily Strain Target feel like it’s actually made for your body’s current state.
App Experience
The best part about WHOOP is that the magic doesn’t actually happen on your wrist, it happens in the app. Whether you have the WHOOP 5.0 or the WHOOP MG, you’re using the same sleek, screen-free interface. It feels more like a high-end data dashboard for your body than just another fitness app.
However, the insights you see depend on your gear. On the WHOOP 5.0, you’ll focus on the Big Three: Sleep, Strain, and Recovery. It’s perfect for seeing how your last workout affected you. But when I used the WHOOP MG, a new Heart Section unlocked, giving me access to the Heart Screener and Blood Pressure Insights, clinical tools that the standard version doesn’t have.
What I really love about the WHOOP MG’s app experience is how it handles this complex medical data. It doesn’t just show a scary graph, it explains your ECG results in simple English and even lets you create a PDF report to send to your doctor.
On both devices, you get the WHOOP Coach, which is an AI that feels surprisingly human when explaining exactly why your recovery is low or how to fix your sleep.
Battery Life and Charging
Both the WHOOP 5.0 and WHOOP MG are total game-changers, giving you a massive 14+ days of battery life on a single charge.
You can power up without ever taking the band off by simply sliding on the waterproof Wireless PowerPack, which fully recharges the device in about two hours.
Subscription and Pricing
When you pick a WHOOP, you aren’t just choosing a device, you’re choosing a membership tier. WHOOP now has three main levels and the hardware you get depends on which one you pay for.
If you have an HSA/FSA account, you can use it for WHOOP. Here is how the costs break down:
- WHOOP One ($199/year): This is the budget entry point. It comes with the WHOOP 5.0 and a basic corded charger. You get all the core stats like sleep, strain and recovery, but you miss out on some of the newer, advanced health tracking.
- WHOOP Peak ($239/year): This is the most popular choice. It also uses the WHOOP 5.0 hardware but includes the Wireless PowerPack (the one that lets you charge while wearing it) and unlocks Healthspan features like your WHOOP Age.
- WHOOP Life ($359/year): This is the only way to get the WHOOP MG (Medical Grade) hardware. It’s the premium experience, giving you everything in the Peak plan plus the ECG and blood pressure tools.
Real-World Value: Do You Need MG?
When I switched from the 5.0 to the MG, I realized the Medical Grade label isn’t just marketing, it actually changes how you interact with the app. Here is a breakdown of when that extra cost translates into real-world value and when it’s probably overkill:
- Heart Health Peace of Mind: The standout feature is the on-demand ECG. If you have a family history of heart issues or ever feel a random flutter, being able to take a 30-second reading and generate a PDF report for your doctor is a massive weight off your shoulders.
- Morning Blood Pressure Trends: While it’s not a replacement for a clinical cuff, the WHOOP MG gives you systolic and diastolic trends while you sleep. I found this incredibly helpful for seeing how a stressful work week or a few late-night drinks physically impacted my baseline the next morning.
- Advanced Longevity Tracking: The MG is built for the healthspan-obsessed. It uses a more sensitive medical-grade sensor to give you a more precise WHOOP Age and pace of aging. If you’re actively trying to de-age your biology, the WHOOP MG provides the high-fidelity data you need.
- The Metal Clasp Experience: On a purely tactical level, the WHOOP MG feels more premium. The metal clasp houses the ECG contacts and it feels much sturdier than the WHOOP 5.0’s composite clasp. If you’re someone who is rough on their gear, the WHOOP MG hardware feels like it can take a serious beating.
Who Should Choose WHOOP 5.0
You can choose WHOOP 5.0 if:
- You want the most affordable entry into the WHOOP ecosystem.
- You are primarily focused on tracking gym performance, strain and recovery.
- You prefer a lightweight, ultra-slim tracker that stays out of the way.
- You only need core health stats like sleep stages and resting heart rate.
- You want the long 14-day battery life without paying for medical sensors.
- You are a healthy athlete who doesn’t need to monitor chronic heart conditions.
- You want a simple, actionable Green or Red recovery score every morning.
Who Should Choose Whoop MG
You can choose WHOOP MG if :
- You want medical-grade heart monitoring with an FDA-cleared ECG.
- You need daily blood pressure insights to track your cardiovascular health.
- You prioritise longevity and want to track your Biological Age (WHOOP Age).
- You want the most premium hardware featuring the specialised metal clasp.
- You have a family history of heart issues and want the Heart Screener alerts.
- You are a data-heavy user who wants every possible biometric measured.
Who Should Avoid Both
Even though I’ve loved my time with both bands, WHOOP definitely isn’t for everyone. You should probably avoid both the WHOOP 5.0 and the WHOOP MG if:
- You need a watch face to check the time: Since there is no screen, you’ll still be reaching for your phone just to see what time it is.
- You want to see live stats during a run: If you’re a runner who needs to see your pace, distance or split times in real-time on your wrist, you’ll be much happier with a Garmin or Apple Watch.
- You hate monthly subscription fees: WHOOP requires a membership to work. If you prefer to buy it once and own it forever, the long-term cost of WHOOP will eventually frustrate you. If that’s you, you can look at some of the WHOOP alternatives that are subscription-free.
- You want smart features like GPS or Music: These bands don’t have built-in GPS or the ability to control your Spotify playlists they are strictly data-collection tools.
- You need a Step Counter on your wrist: While the WHOOP 5.0 and WHOOP MG finally track steps in the app, you won’t get that satisfying 10,000 steps buzz on your arm as you do with a Fitbit.
- You find 24/7 wear intrusive: To get accurate data, you have to wear these almost constantly. If you don’t like wearing something while you sleep or shower, the data won’t be worth the price.
Final Verdict
If I’m being completely honest, the WHOOP 5.0 is the perfect choice for most people. It gives you that amazing 14-day battery life, a smaller design and all the recovery data that made WHOOP famous without the huge price jump. If you just want to track your workouts, improve your sleep and keep things simple, the WHOOP 5.0 is more than enough to help you change the way you train and rest.
On the other hand, the WHOOP MG is the ultimate choice if you’re focused on longevity. For me, I would choose the MG for an elderly member of my family, wherein having an FDA-cleared Heart Screener and blood pressure trends right on their wrist would give me true peace of mind.
If you have a family history of heart issues or simply want the most clinical data possible, the MG is worth the upgrade. It’s not just a workout tool, it’s a tiny, 24/7 medical safety net. But if you’re just someone who wants to upgrade their health tracking experience, the WHOOP 5.0 is a great choice!
