Gone to seed instead of going for speed? A fitness tracker is a useful tool for monitoring and measuring your physical activity.
Before you buy, consider your fitness goals. Are you trying to jump-start a lapsed fitness routine? Fine-tune an exercise regimen? Train for a triathlon? The right fitness tracker can help you achieve your specific objectives.
Fitness trackers range from simple to sophisticated, with prices to match. Here’s how to find the right tracker to fit your budget, fitness goals, lifestyle, and fashion sense.
Keep in mind that a fitness tracker is like a gym membership: It’s beneficial only if you use it.
All trackers use sensors to monitor your movements, often connecting and syncing wirelessly with a computer or mobile device to store data about your day-to-day activities. The types of data monitored vary by tracker but can include number of steps taken, hours of sleep, heart rate, skin temperature, and perspiration levels.
Most trackers use an accelerometer to help measure your steps and other up-down, side-to-side, and front-to-back movements.
Additional sensors may include:
• Heart rate monitor to track your pulse during exercise and throughout the day.
• Blood-oxygen tracker to monitor how well your body is using oxygen. Once reserved for smartwatches, this feature is starting to pop up in trackers.
• Gyroscope to determine whether you’re standing, sitting, reclining, swimming, cycling, etc.
• GPS to track your location.
• Magnetometer to detect specific movements and determine which direction you’re moving in.
• Barometer to determine your altitude, which is used to calculate how many flights of stairs you climbed this morning to get to your office.
Some fitness trackers can be synced with external heart monitors, smart bathroom scales, and other devices that offer more precise readings. When paired with the companion software or mobile app (or even third-party apps, in some cases), trackers can give you insight into your daily habits.
A number of models offer smartwatch-like alerts for incoming calls, texts, instant messages, and e-mail. And they can provide motivational support in the guise of challenges, badges, interaction with online friends, and a vibrating alert when it’s time to get up and move. They can even share data remotely with your doctor.
Fitness trackers are designed to accommodate a range of requirements. If you simply want to know how many steps you’re taking each day, opt for a basic model that costs less than $100.
If you want details on the speed, pace, and stride associated with your steps, along with your average heart rate and insights into how much (and how well) you’re sleeping, you’re going to need something more advanced. Some models can even provide data tailored specifically to the routines of avid swimmers, golfers, skiers, weightlifters, or marathon runners.
But if you’re really into both productivity and fitness, check out our smartwatch ratings. Unlike fitness trackers, smartwatches let you install third-party apps. And while they still tend to be a bit more expensive than fitness trackers, the cost gap between the two kinds of devices has narrowed in recent years.
Here’s what basic fitness trackers typically measure:
• Steps taken
• Heart rate
• Duration of exercise
• Active minutes
• Sleep time (sometimes divided into regular and REM)
Once you’ve decided on the functions you want, you can refine your options based on personal taste.
In the past, fitness trackers tended to look purely functional, but manufacturers are now more conscious of style. You can find a variety of materials, shapes, and colors—and some models created in collaboration with bona fide fashion designers. Choose a look you’ll feel comfortable wearing every day.
The more advanced trackers reveal their data—using words, numbers, and symbols—on a watch-face-like display. Others share that info via a simple LED display or only through an app. When you sync the data to your smartphone or computer, the tracker’s companion app not only archives the information but also helps you interpret and analyze it. Before you make a final purchase decision, preview the tracker’s companion app to make sure it lives up to your expectations.
Trackers are not foolproof. They use sensors and algorithms to parse footsteps, punches thrown, stairs climbed, hours slept. That means there’s some degree of imprecision. If you need hard data, you may want to pursue a function-specific device. In general, heart rate monitors that strap to your chest and transmit info to your activity tracker are more precise than the in-device sensors applied to your wrist.
Depending on the sophistication of the device, battery life can stretch from one day to several months. The battery in a tracker with a color touch screen and an armada of sensors is likely to need charging more frequently than the battery in a simple band with a few LED lights on its face.
How often do you encounter water when you work out? That’s an important consideration, too. Most trackers are at least splashproof. Others can withstand a hardy shower—indoors or out. But if you’re going to wear your tracker in the pool, you should look for one with a higher level of water resistance.
