The main difference between Whoop 4.0 and Whoop 5.0 lies in the more compact dimensions, a claimed battery life of over 14 days, and a new three-tier subscription system (One, Peak, and Life), while the MG variant adds features like ECG and blood pressure estimates. In daily use, the philosophy (no screen, data read via app) and the requirement for a subscription remain the same. There is also a practical aspect often underestimated: the straps for the 4.0 generation are not compatible with the 5.0 and MG, and vice versa. Let's look at everything carefully to help you decide whether to stick with what you have, switch, or choose the right generation for your first purchase.

Overview: three devices, one philosophy
Whoop is a screenless band: you wear it and it records, while you read the analysis and recommendations in the app. This concept has remained identical across generations. The Whoop 4.0 is the device many know and which built the brand's reputation. In 2025, the Whoop 5.0 and Whoop MG arrived, which maintain the same approach but change in dimensions, battery life, sensors, and commercial structure.
A fundamental point: you don't buy a Whoop like a normal gadget with a one-time price. The device is included in the subscription, which is mandatory. For this reason, when comparing generations, one must talk not only about hardware but also about the chosen subscription level. If you want an analysis dedicated to costs, you can find everything in our article on how much Whoop costs in Italy.
The information in this guide is meant to help you find your way. Specifications, prices, and functions may change: for updated details, always consult the official website whoop.com.
What really changes between Whoop 4.0 and Whoop 5.0
Dimensions and comfort
The device for Whoop 5.0 and MG is smaller compared to the 4.0. In an object worn twenty-four-seven, even a few millimeters count: less bulk means less discomfort under a sleeve, during sleep, or during exercises where the wrist works a lot, such as pull-ups, push-ups, or weightlifting.
Battery life
The new generation claims a battery life of over 14 days. The concrete advantage is charging less often and reducing the risk of "gaps" in your data. As always, real-world battery life depends on usage, active features, and conditions: the declared values are a reference, not a guarantee.
Sensors and features
Whoop 5.0 and MG introduce an update to the sensors and new features compared to the previous generation. We prefer not to list every technical detail we cannot verify precisely: for the complete and updated list of metrics available on your subscription level, the correct source is the manufacturer's official page.
Subscription structure
With the new generation, there are three levels: One, Peak, and Life. Each includes the device and unlocks a different set of features. We will look at them in detail below.

Whoop MG: ECG and blood pressure
Whoop MG is the most complete version of the new generation and is associated with the Life level. Compared to the 5.0, it adds ECG and blood pressure estimates. A key clarification is needed here: these features, like everything related to health data, do not replace medical visits or tools. If you have symptoms, concerns about your heart or blood pressure, or a diagnosed condition, your doctor is the person to consult. Whether and to what extent a feature is certified or authorized in your country is determined by the manufacturer; therefore, check the official statement on whoop.com.
For those who use Whoop primarily for training and recovery, this difference may not be decisive. For those who want to carefully monitor certain parameters related to cardiovascular health, MG may be an option to consider, always keeping in mind the aforementioned limitations.
One, Peak, and Life subscriptions
The indicative annual prices in Italy are as follows (always verify on the official site as they may change):
- One: about €199 per year, the entry-level tier.
- Peak: about €264 per year, the mid-tier level with additional features.
- Life: about €399 per year, the full-featured level associated with Whoop MG.
The device is included in the subscription in all cases. To know in detail what each level unlocks, compare the official pages: we simply remind you of the general logic, which is that the higher you go, the more advanced features you get, up to ECG and blood pressure estimates on the Life level with MG.
A "fair" comparison point
Comparing a 4.0 model to a 5.0 just by looking at the hardware makes little sense. The correct question is: which combination of device and subscription level do I need? A person who uses Whoop for sleep and training may find the base level sufficient; someone who wants the most advanced features will look at the higher level.
Comparison table
Summary of the main points, based on known official information. For exact details, consult whoop.com.

Straps: what happens if you change generations
For those who own accessories, the issue is real. According to the official WHOOP community, 4.0 generation straps are not compatible with the 5.0 and MG because the newer devices are smaller and have different Fast Links. Likewise, 5.0/MG straps are not compatible with the 4.0.
This means that if you upgrade from one generation to another, the straps you have in your drawer cannot be reused. It's better to do the math first: if you have invested in several straps, the cost of an upgrade also includes replacing those accessories. A complete overview of materials and options is in our complete guide to Whoop straps.
Where to find VELVEN straps for each model
Our Hydroknits are sold in separate variants for Whoop 4 and Whoop 5 for €29.99 in the Hydroknit collection. Other collections to browse:
- Top picks, to start from a selection.
- Waterproof: two-tone silicone designed to resist water.
- Classic: solid-colored elastic nylon.
On every product page, check the variant and compatibility with your device before purchasing.
Is it worth upgrading from the 4.0?
There is no one-size-fits-all answer. Here is a reasoning framework.
Reasons to consider upgrading to the new generation
- The bulk of your current device bothers you, or you charge it too often.
- You are interested in ECG and blood pressure estimates (therefore MG with Life level).
- You want access to the features of the new subscription levels.
- Your device is damaged or has malfunctions.
Reasons to stay with the 4.0
- You are happy with it and use Whoop primarily for sleep, recovery, and strain.
- You already own several 4.0 straps that you would have to buy again.
- The cost of the upgrade is not justified by the features you would actually use.
Upgrade conditions for existing subscribers (prices, potential offers, timelines) are determined by the manufacturer: consult the official page or WHOOP support before deciding.
Scenarios for choice
Scenario 1: you are buying your first Whoop
Start with the most recent generation, because that is where the manufacturer focuses its innovations. Then choose the subscription level based on what you actually want to measure. If you are not yet sure if Whoop is right for you, read is Whoop worth it first, and see the comparison with other solutions in Whoop vs Apple Watch, Oura, and Garmin.
Scenario 2: you have a 4.0 and it works well
You are likely in no hurry. Evaluate what you feel you are missing. If the answer is "nothing in particular," staying put is a rational choice. In the meantime, you can freshen up your style with new straps compatible with your generation.
Scenario 3: you train every day and want more comfort
A smaller device and longer battery life can make a difference. If you train with weights or CrossFit, take a look at Whoop for running, gym, and CrossFit.
Scenario 4: you are interested in cardiovascular parameters
MG with the Life level is the only one that offers ECG and blood pressure estimates. Remember, however, that these are wellness tools: if you have clinical reasons for monitoring yourself, you need a doctor's opinion.
Scenario 5: you want to spend as little as possible
Start with the One level and calculate the annual cost. Don't forget that you have accessory straps at different price points, which are useful for changing your look without touching your subscription.
Two straps, one saving: with code DUE15, get 15% off when you buy two VELVEN straps. A silicone one for training and a nylon one from our icons and quotes collection are a common combination.
Common mistakes
- Confusing generation and strap: buying a 4.0 strap for a 5.0 (or vice versa).
- Looking only at the hardware: ignoring the subscription level and annual cost.
- Taking a fixed price for granted: prices can change, always check the official site.
- Expecting medical functions: Whoop is for wellness, except for certified functions declared by the manufacturer.
- Changing by habit: the latest model isn't always the right one for you.
Decision checklist
- Have I identified my current model (4.0 or 5.0/MG)?
- Which features do I actually use every week?
- Do I need ECG and blood pressure estimates?
- How much do I spend per year with the level I'm interested in?
- How many straps would I have to repurchase?
- Have I read the updated conditions on whoop.com?
