Buying guide forBest fitness trackers

健身跟踪是一个小,方便设备that can change the way you track your activity and wellness. Whether you’re looking for a simple step counter, a sleep tracker, or a versatile smartwatch, these devices designed expressly for fitness tracking can make it easier for you to adopt positive lifestyle changes.


While fitness trackers aren’t guaranteed to improve fitness, owning and using one can help you keep an eye on your overall performance.

Because a tracker is comfortable to wear, it may be easier for you to use during exercise than carrying a smartphone.

How it looks


Models with display screens

Fitness trackers with display screens are common. Many look like wristwatches. Because these trackers are so comfortable to wear, many people find them far more convenient than exercising with a smartphone.

How it fits

Most trackers are wearable; many fit the wrist. Other options exist, however, including a clip-on tracker for a collar or pocket. Necklace designs are also available, as are units that clip to a shoe or ankle. Look for a fit that corresponds to the type of exercise you enjoy.

A fitness tracker on your wrist won’t track heart rate as accurately as a medical monitor strapped to your chest.


Where it works

Most fitness trackers can withstand any exercise environment you encounter. Neither cold nor hot weather should affect them. But if you want a tracker for swimming, you’ll need a model that is wearable underwater. Some fitness trackers can withstand water submersion, but most cannot.

Colder weather can drain the battery faster than warm weather, so keep that in mind before your next winter marathon.

If you use a smartphone app now to track your exercise routine, understand that a fitness tracker device works a little differently. A tracker measures certain aspects of your movement. It then pairs with an app to determine whether you’re meeting your goals. Fitness trackers can track some interesting aspects of your movement, including the following —

  • Steps:This is often the most basic type of information measured. You can use it to gauge exactly how much you move throughout the day.
  • 心率:Many fitness trackers act as a heart-rate monitor during periods of exercise as well as rest. One way to gauge an improving fitness level is by an improved heart rate at rest.
  • 睡觉:If you aren’t sleeping well, your overall health will suffer. Some fitness trackers offer sleep tracking. By measuring your movements during the night, you gain information about the quality of your rest.
  • Overall workouts:Unless a fitness tracker has a GPS chip built into it, it won’t be as effective at tracking some workouts. You need GPS capability to determine how far you ran or biked, for instance. The fitness tracker’s app enters the picture here, as it can track many types of workouts successfully.
  • Sports apps:Some trackers, like the Garmin vivoactive, give you the ability to track your performance in specific sports, such as golfing or biking.

Caloric burn readings can be inaccurate based on the watch’s algorithms and should be used as a guesstimate.

How a fitness tracker works

Fitness trackers provide the data listed above thanks to a variety of internal components.

Motion sensing

Much of a fitness tracker’s data collection occurs courtesy of its motion-sensing components. For example, here’s a look at how a tracker uses motion-sensing technology to monitor your sleep: a三轴加速度计确定您正在移动哪个方向,一个gyroscopemeasures the rotation of the fitness tracker. Using these technologies, the tracker measures your wrist movement during sleep, judging the frequency and force behind the moves. Software in the app then determines whether you’re moving often enough during the night to cause you to sleep poorly.

If your fitness tracker has a GPS built into it, its battery life probably will be less than average.



Having a GPS unit on a wearable fitness tracker is great for runners and bikers. This feature allows the unit to measure the distance you’ve traveled, even if you’re running or riding in a rural location.

Optical sensors



Rather than optical sensors, some fitness trackers place tiny electrodes against your skin. The tracker is then able to act as a heart rate monitor. A fitness tracker with生物阻抗传感器should be more accurate than one with optical sensors.

Measuring altitude

Some mid-range and high-end fitness trackers include analtimeter,一种测量您当前高度的设备。这种测量对在山区锻炼的远程跑步者有帮助。如果爬楼梯是您锻炼程序的一部分,则高度计可以确定您的攀爬高度。

Temperature sensor

Some high-end fitness trackers include a temperature sensor that rests against your skin. This measurement can help determine if you’re overheating during an especially tough workout.

Trackers attempt to ignore false motion readings, like if you hit a bump while driving in the car. But sometimes the unit may ignore some of your steps, thinking they’re false readings.

Working with the app

Because fitness trackers are such simple devices, many cannot analyze your exercise results on their own. Instead, these units rely on an app to show you your activity results. If at all possible, you will want to look at the app before you pick a fitness tracker. Make sure it has all of the features you need. And make sure it will work with your iOS or Android smartphone before you buy it, as some apps are limited to one type of smartphone operating system.


Real-time data tracking

As these devices grow more sophisticated, some have begun to offer data tracking in “real time.” For example, a tracker with built-in GPS may not need to sync your data with an app to provide you with pace and distance data. If you are looking for a running watch with such a benefit, expect to pay at least $100 for it, and note that this feature is not offered by all devices … yet.

Make sure the app can track your favorite types of exercise. If you’re a swimmer, the app should be able to time your laps and measure distance. If you’re a runner, you may want it to take notes about the type of weather you encountered on a particular run.

And, of course, the more data the fitness tracker can send to the app related to your favorite exercise, the better. You don’t want to spend a lot of time entering your own information. After all, that's the point of wearing the fitness tracker: it measures and records your activity for you.

Be sure to enjoy workouts, and try to avoid becoming too attached to reading your watch’s display while exercising. Take breaks and enjoy the scenery and your workout environment. Many of us spend lots of time looking at screens, so exercise can be an opportunity for a break from screen time.

最不昂贵(最高$ 50)

Fitness trackers can start as low as$15. Just don’t expect these basic models to generate a huge amount of data. You might receive information about steps taken and calories burned with these inexpensive activity trackers, and some even offer sleep tracking. However, you’re not likely to find a fitness tracker with a touchscreen display on its watch face; these inexpensive trackers typically use LED light indicators instead. Even if it does have a touchscreen, it may be a bit more finicky and less user-friendly than that of a higher-end unit.


An exception is Xiaomi Mi bands, some of the best fitness trackers for those on a sub-$50budget. However, you will need to use the Mi Fit app, which not everyone likes, and some say the band is not best for cardio.

Mid-range ($50 to $100)

中端设备在睡眠(睡眠跟踪)期间的运动以及采取的步骤,燃烧的卡路里以及其他一些基本统计数据中的移动 - 与便宜的健身追踪器相比,它们的可靠性和用户友好性更高。在这个价格级别上有效的健身追踪器的一个主要例子是Fitbit的Inspire HR,该人的Inspire HR首次出现在2019年,自从出现以来就累积了许多粉丝。

最昂贵的(最高$ 500)

Design and fitness features markedly improve as you move into the$100+category. These are the best fitness trackers, made expressly made for people who want to monitor their daily activity and how their habits mesh with their goals. If precision is key for you in terms of blood oxygen saturation, active and resting heart rate tracking, swim tracking, and more, look here for the best buy.

This price tier also appeals to those who want to make contactless payments from their wrist.

Impressive smartwatch features including multiple-day battery life, cellular connectivity, built-in virtual assistant programs (like Alexa), and the ability to stream music through media services like Spotify, are easier to find in this price tier. If you want the best smartwatch/fitness tracker combination possible, look here.

To determine calorie burn, the software applies a formula to the fitness tracker data. Because each unit’s formulas are different, you could feasibly receive two different calorie burn results from two trackers worn at the same time.



  • Some products take heart rate monitoring to the next level.例如,你可以得到一个心电图应用一些苹果Watch Series trackers to measure heart rhythm. The app can check for signs of atrial fibrillation, a condition that can result in serious health problems like stroke.
  • Some products incentivize exercise with points.For example, some Fitbit products offer you the ability to track Active Zone Minutes, a state of heart rate elevation also known as the fat-burning zone. You earn one point for every minute you spend in the fat-burning zone. Push yourself to the cardio zone, and you can earn two points per minute.
  • Some products don’t have GPS built in; instead, they offer “connected GPS.”Buyers should be aware of this distinction. With a product boasting connected GPS, you will need to keep your phone or other tethered device (Android, iPhone) with you. Connected GPS saves the company on manufacturing costs, but some consumers find it a burden.
  • You may be able to get a free trial for subscription services like Fitbit Premium.Fitbit Premium offers some cool extras, such as guided workouts and detailed breakdowns of your health stats. However, it comes at an extra cost that some consumers would rather not pay. You can try this subscription for free, though you may need to enter a payment method first. Some trackers, like the Fitbit Inspire 2, come with an automatic free trial.
  • Some fitness trackers allow you to make payments via smartwatch.For example, if you own a Fitbit, you may be able to use Fitbit Pay. Make sure your bank participates with Fitbit Pay first. Further, some models allow you to make contactless payments, like the Fitbit Charge 4. Similarly, if you own a tracker from the Apple Watch series, you may be able to use Apple Pay.
  • Note whether a product has a long battery life.Nowadays, a span of seven days is considered a long battery life, though a length of 10 days is also offered by some products. Solar charging is an additional option that can extend your battery.
  • You might like working with third-party apps.Third-party apps are unaffiliated with your fitness tracker purchase. Some are free, and some have a cost. Most are compatible with all devices, including iOS, but read the fine print to be sure.

A waterproof tracker is more rugged than a water-resistant tracker. When selecting your product, pay close attention to this language.


Q. I’m highly focused on my fitness goals. Why doesn’t the fitness tracker tell me if my exercise routine is working?


It’s important to realize that health tracking cannot be achieved with this technology alone. We recommend that you share your fitness goals and data with your physician to maximize best results.

Q. How accurate are the calorie burn counts on a fitness tracker?

A. It depends on the model you have. Basic, inexpensive models that don’t have a lot of features often won’t be precise in tracking calorie burning. Generally, the more statistics a particular fitness tracker collects and measures, the more accurately it will measure calorie burn.

Q. What is the biggest benefit of a fitness tracker?

A.A fitness tracker helps you set simple goals and measure your progress toward them. You may want to take 8,000 steps per day, for example. Nearly all tracker units can help you figure out how close you come to this goal each day.

如果您的目标更复杂,例如准备半程马拉松比赛,则可能需要一个高端健身追踪器,并配对专门运行的智能手机应用程序。最新的Fitbit Versa车型具有内置的GPS来帮助这一点。

Q. I’ve been hearing a lot about Amazfit. Is it a brand made by Amazon?

A.No. Amazfit is actually a Chinese company that has successfully established itself in under a decade as an affordable maker of great smartwatches. Although not affiliated with Amazon, Amazfit products can be purchased through Amazon. The company offers a range of fitness trackers, from under $50 to over $100, that measure sophisticated stats like SpO2 (oxygen saturation) and boast multi-day battery life and other cool features, like an always-on display. If you’re interested in Amazfit, we suggest checking their offerings on Amazon to find the best buy.
