Amazon Halo vs Whoop 4.0 Strap: A Comparison

Amazon Halo vs Whoop: Key Points Comparison

In this review, we will compare the Whoop fitness band and the Amazon Halo wearable to determine which one is better suited for monitoring sleep, tracking activity, and tracking recovery for you. We'll delve into the details, exploring their design, features, and overall performance. By the end, you will have a clearer understanding of which device may be the ideal choice for you, Halo vs Whoop.

I am passionate about fitness and am a marathon runner and a triathlete. I take my fitness seriously and monitor it as well as make fitness goals. For me narrowing it down is simple.

There are many other fitness bands, and brands, some are great options that have screens like the Fitbit Charge, Apple Watch, or Oura Ring. We'll keep this article focused on health wearables for data collection that do not have screens and are meant for the wrist.

Fitness Wearables Help Support a Healthy Lifestyle

How do fitness wearables work?

Just like any smartwatch with GPS, and real-time data, these measure more subtle data given off by the body, but are more of a specialty item for fitness enthusiasts and last longer in terms of battery charge.


Both Whoop's signature product and Amazon Halo have distinct design characteristics. The Whoop band features a sleek, minimalist design with a fabric strap, while the Amazon Halo offers a more traditional fitness band appearance with a silicone strap (other strap options are available). The design preference largely depends on personal taste and comfort.

Sleep Monitoring:

Sleep tracking is a crucial aspect of fitness bands. Whoop is known for its advanced sleep tracking capabilities, providing in-depth analysis of sleep stages, heart rate variability, and respiratory rate. On the other hand, the Amazon Halo also offers sleep monitoring features but may not provide the same level of detailed insights as Whoop 4.0.

Activity Tracking:

Both devices excel in activity tracking but specialize in different types of data. Whoop provides detailed data on heart rate, calories burned, and active minutes, allowing users to monitor their exercise intensity and overall activity levels (actionable information). You earn activity points in real-time. with your monthly membership fee.  Similarly, the Amazon Halo offers the usual activity tracking features, including step counting (Whoop does many things, but step counting is not one of them, they think it isn't useful) and active calorie tracking, providing users with a comprehensive view of their general daily activities.

Recovery Tracking:

Whoop is renowned for its recovery tracking capabilities, utilizing metrics such as heart rate variability and sleep data to determine an individual's readiness for physical exertion. While the Amazon Halo provides insights into overall health and wellness, it does not offer the same level of recovery-focused features as Whoop.


Pricing is an important consideration when choosing a fitness band. Whoop operates on a monthly subscription-based model, requiring a monthly or annual membership fee in addition to the initial cost of the device. On the other hand, the Amazon Halo is available for a one-time purchase price without any recurring fees. The choice between a subscription-based model and a one-time purchase depends on personal budget and preferences

Between Amazon's Halo Band and Whoop 4.0 in terms of fitness and health tracking capabilities.

When it comes to fitness bands, the Amazon Halo Band and Whoop 4.0 are two popular options that offer unique features and functionalities. In this article, we will delve into a comparison of these screenless health wearables, which vary in the key areas mentioned above, exploring their key differences in terms of features, tracking capabilities, subscription models, app interfaces, battery life, and more. By the end, you will better understand which fitness band is better suited to your needs and preferences.

Amazon Halo:

The Amazon Halo Band, released in 2021, comes in two models: the essential Halo Band and the Halo Band 2, which features a small display. The Halo Band focuses on providing essential health metrics and features such as step counting, sleep tracking, body composition analysis, and personalized 3D body models. It offers essential heart rate monitoring but lacks advanced cardiac metrics and SpO2 monitoring. SpO2 is a measure of oxygen saturation or how well your body is taking in oxygen. In a hospital setting the technology is called pulse oximetry. 90% or better is normal depending on altitude.

It's important to note that access to advanced features and statistics beyond steps and heart rate requires a monthly subscription. Additionally, the Amazon Halo app provides a straightforward interface, with basic health metrics visible even without membership though the 3.99/month membership plan is recommended.

However, the Amazon Halo fitness app does not integrate with any third-party apps, so its functionality is limited to what you got on day one.

The battery life of the Amazon Halo Band lasts almost a week, but the "Tone Analysis" feature can consume battery power 3x faster.

The Tone Analysis is what makes some gadget reviewers stop cold in their tracks. Described by Apple Insider as "incredibly invasive" but good for finding out more about yourself (if you're into that).

Whoop 4.0:

The Whoop 4.0, launched in 2022, operates on a subscription-based model and is made for the serious athlete interested in a change of lifestyle. The app comes in the form of a widget which makes it easier to reference.

The Whoop was designed with many competitors and despite this, they kept the vision of the product the same. The CEO wanted to focus on more sensitive and scientifically-based measures like HRV (heart rate variability) and Recovery metrics, not the usual steps, distance, and calories that are common to all fitness trackers.

It collects a wide range of biometric data, including heart rate, heart rate variability, blood oxygen saturation (blood oxygen level), breathing rates, daily steps, body temperature, and sleep REM cycles. Whoop offers more detailed and focused health and fitness insights than Amazon Halo, with detailed breakdowns of nightly activities and personalized workout and nutrition recommendations.

Whoop's sleep-tracking capabilities are particularly noteworthy. The Whoop Strap 4.0's app interface provides detailed weekly and monthly graphs, allowing for comparisons of metrics.

It integrates with Apple Health and Strava, enabling seamless data synchronization, whereas the Amazon Halo fitness app does not integrate with other apps.

Similar to the Amazon Halo, the Whoop 4.0 has a battery life of almost a week, making it convenient for daily wear. The device charges with a water-resistant battery pack while being worn, eliminating the need to remove it for charging.

How Accurate are Amazon Halo Body Composition Metrics?

Most digital scales measuring body weight do some sort of body composition analysis, and like the Amazon Halo, also make body composition approximations. These are only approximations and are a guide to changes, not an actual assessment of your body composition. To actually determine all that the proper way, it costs a great deal more than buying a fitness wearable. Take these measurements with a grain of salt. They may seem consistent for you day to day, but a measurement on another device may give a very different reading.  For example, it said that I am 7% body fat and that's too low to be accurate. The body composition features are only available with the paid monthly membership (subscription).

Choosing the Right Fitness Band:

When deciding between the Amazon Halo and Whoop 4.0, several factors come into play. Budgets, concerns, preferences, and usage patterns all play a role in making the best purchase decision. For most individuals, the Amazon Halo may be more cost-effective in the long run, as it offers a one-time purchase option. However, athletes and fitness enthusiasts who prioritize in-depth insights and recovery-focused features may find the Whoop 4.0 to be a better fit. Additionally, the Amazon Halo app provides basic health metrics without a membership, while Whoop offers more comprehensive weekly and monthly graphs.

Both the Amazon Halo and Whoop 4.0 are fitness bands that offer valuable tracking capabilities for activity, sleep, and other health metrics. The Amazon Halo emphasizes essential features, body composition analysis, and a more straightforward app interface. On the other hand, Whoop excels in providing detailed insights, especially in sleep tracking, along with personalized recommendations for workouts and nutrition. Ultimately, the choice between these fitness bands depends on your individual needs, preferences, and budgetary considerations. Evaluate the features and functionalities that align with your goals to make an informed decision on which fitness band is right for you.

Key Takeaway:
The comparison between Amazon Halo and Whoop 4.0 reveals that both fitness bands have their unique features and advantages. Amazon Halo is more cost-effective and offers basic health and fitness tracking, while Whoop provides detailed insights and biometric data. The choice depends on individual preferences, budget, and usage patterns.

Amazon Halo vs Whoop 4.0: Which Fitness Band Is Right for You?

Both the Amazon Halo and Whoop 4.0 are fitness bands that track your activity, sleep, and other health metrics. However, there are some key differences between the two devices. The setup process is simple and the same for both.

Amazon Halo

The Amazon Halo is a new fitness band from Amazon that was released in 2021. It is available in two models: the Halo Band and the Halo Band 2. The Halo Band is the basic model and it does not have a display. The Halo Band 2 has a small app display that shows your heart rate, steps, and other metrics but no GPS. The design allows for more strap options of different materials or colors than the Whoop.

The Amazon Halo tracks a variety of health metrics, including:

  • Activity: The Halo Band tracks steps, distance, calories burned, and active minutes.
  • Sleep: The Halo Band tracks sleep duration, sleep stages, and restlessness.
  • Heart rate: The Halo Band tracks your heart rate throughout the day.
  • Body composition: The Halo Band uses a new technology called Body Composition Insights to estimate your body fat percentage, muscle mass, and bone density. These are very rough measures and are at best, weak approximations. (Actual body composition testing costs thousands of dollars).

The Amazon Halo also has a few unique features, including:

  • Tone: The Tone feature uses artificial intelligence to analyze your voice and give you feedback on your tone of voice.
  • Social feature: The Social feature allows you to share your fitness data with friends and family.

Whoop Strap 4.0

The Whoop 4.0 is a fitness band that was released in 2022. It is a monthly subscription-based device, which means you will need to pay a monthly fee to use it.

The Whoop 4.0 tracks a variety of health metrics to help you meet your fitness goals, including:

  • Activity: The Whoop 4.0 tracks steps, distance, calories burned, and active minutes.
  • Sleep: The Whoop 4.0 tracks sleep duration, sleep stages, and restlessness.
  • Heart rate: The Whoop 4.0 tracks your heart rate throughout the day.
  • Recovery: The Whoop 4.0 tracks your recovery status and gives you recommendations on how to improve your recovery before you start the day.

The Whoop 4.0 also has a few unique features, including:

  • Strain: The Strain feature measures the overall stress on your body. This is more useful than guesses at your body fat percentage. Physiologists understand that recovery is just as important as exertion.
  • Whoop Journal: The Whoop Journal is a personalized dashboard that provides you with insights into your health and fitness.


The Amazon Halo and Whoop 4.0 both track a variety of health metrics, including activity, sleep, heart rate, and body composition. Both devices also have unique features that can help you improve your health and fitness. The choice will be about the type of data collected or pricing in this head-to-head comparison, where the two differ most.


The main difference between the Amazon Halo and Whoop 4.0 is the price. The Amazon Halo is a one-time purchase, while the Whoop 4.0 is a subscription-based device. The Amazon Halo also has a few features that Whoop 4.0 does not have, such as Tone and Social.

The data collected

A Word about Amazon Tone Function:

Privacy concerns may become an issue here for some people, particularly with health wearables and smartwatches. If you are fine leaving Alexa, Google, and Siri, on all the time, you may not think anything of the devices that may be recording audio and/or video without you knowing. The Amazon Tone feature is flat-out disturbing to some reviewers. Amazon is allowing its consumers to cross over a line unaware when it comes to "Tone".

Many reviewers find the Amazon Halo like me and learning about what Tone collects from you are justifiably creeped out at how invasive it is to measure things that aren't necessarily fitness related like vocal intonation and quality. Does it actually measure what it intends to? If not, it's not a valid test.

It records audio of you and your surroundings at all times. But to do some of the fat % calculations you need to upload photos of you that reveal parts of your body. Do you need to send images of you and store sounds you make with a company database? That's up to you. Those tests also require the optional subscription fee and for figures that don't change from month to month anyway, there is no point, in my opinion.

I shut off Alexa unless I need to speak to it and don't allow devices to listen for "Hey Siri" or "Ok Google". At one point, these were amusing novelties, now they are reminders that you're being watched en masse by both governments and corporations and that data leakage to them is a serious concern for all people.

While there are reassurances your data doesn't stay in memory and isn't loaded to the cloud with Amazon Tone analysis, I'd rather never deal with it.

Which Fitness Band Is Right for You?

The best fitness band for you will depend on your individual needs and preferences. If you are looking for a one-time purchase device with a variety of features, then the Amazon Halo is a good option. If you are looking for a serious activity tracker and don't mind a monthly subscription-based device, then Whoop 4.0 is the best option out there.

Here is a table that summarizes the key differences between the Amazon Halo and Whoop 4.0:

Feature Amazon Halo Whoop 4.0
Price One-time purchase Subscription-based
Display No display, 5 LEDs No Display
Health metrics tracked Activity, sleep, heart rate, body composition Activity, sleep, heart rate, recovery, strain
Unique feature: Tone Analysis, Halo Social Strain, Whoop Journal
Subscription price $3.99 per month (after 6 free months) $39.99 per month


The Amazon Halo and Whoop 4.0 are both great fitness bands that can help you improve your health and fitness. The best choice for you will depend on your individual needs and preferences.
