Fitbit Charge 2

Count More Than Steps

There's never been a better selection of fitness trackers, but with choice comes confusion. Which tracker has the features that are right for you and the activities you do? Here are some tips and recommendations for choosing the best tracker for your needs.

First Steps

If you want to give fitness tracking a try (but without a wearable), start by using a mobile app that counts your steps. This method requires the least commitment, and could be of interest if you're a beginner. Some apps we like are Argus, Fitbit, and Moves.

If you run or bicycle, we recommend tracking your runs or rides with an app before going whole-hog and splurging on a tracker. Why? With some trackers, you still need to carry your phone to get accurate pacing, distance, and mapping, so you'll want to know before you make a purchase if you're okay with carrying your phone, or if you'd prefer a tracker with built-in GPS so you don't have to. A few apps we recommend are Runtastic PRO (for running), Cyclemeter (for bicycling), and Strava (for both running and cycling).

The Coros Linx Smart Helmet is another interesting solution for cyclists that integrates your phone's GPS to track your rides and uses bone-conduction audio to let you hear directions, music, and phone calls without blocking your ears.

Set Your Spending Limit

In general, most fitness trackers cost between $50 and $250. If you pay less than $50, you'll probably get a subpar product with mediocre accuracy. In addition, less expensive trackers usually don't have a display, so you can't see how many steps you've taken unless you look at your smartphone.

More expensive trackers usually include built-in optical heart rate monitors and GPS, and often, these features are tailored toward athletes and exercise enthusiasts. Don't get suckered into buying a tracker with a heart rate monitor if your primary activity is walking; it's an unnecessary expense. If you walk and don't do much else, there are great options in the $49 to $149 range.

If you do work out often, we highly recommend spending at least $99, as that's the price point where you'll start to see the features that are useful to very active users.

Choose Your Style: Bracelet, Clip, Watch

A very important question to ask yourself before choosing a fitness tracker is the type of form factor you want. Fitness trackers are usually bracelets, watches, or clip-ons. Most clip-on devices these days can also be worn on the wrist, but not vice versa. Bracelets and watches are hard to lose. Clip-ons can fall off or get thrown into the wash.

That said, bracelets and watches can get in the way when typing on a computer or washing dishes, for example. And wrist-worn devices aren't always eye-catching accessories to your outfit. If you're bothered by having something on your wrist 24/7, you're probably better off with a clip-on, although this style isn't nearly as popular as it used to be a few years ago.

Clip-on devices are smaller and more discreet when worn on a waistband or the front of a bra. Most don't have displays, meaning you have to rely on a smartphone to see your tracked activity.

The Motiv Ring, meanwhile, brings fitness tracking to your fingers. It tracks many of the same metrics as wrist-worn models in a discreet form factor that looks like jewelry.

And don't forget about Fido. That's right, there are even trackers out there specifically for pets.

Do You Want Heart Rate Monitoring?

Heart rate monitoring sounds like the best feature ever, but there are different kinds of heart rate monitors, and frankly, some people don't need it at all. A built-in heart rate monitor drives up the price.

Optical heart rate monitors are the ones built into the device itself. The Fitbit Charge 2 has one, for instance, among others. Some very good fitness trackers don't have a heart rate monitor built in, but can pair with a chest strap. Most every device from Garmin and Polar supports a chest strap (like the super Polar H10), and you can usually bundle one in when purchasing a tracker for an extra $40 or $50.

Finally, if you're interested in knowing your resting heart rate, you don't need to buy a tracker with an optical heart rate monitor to find it. Many smartphone apps let you take your heart rate in about 15 seconds using the phone's camera. Check your pulse once or twice a day, and you're good to go.

Will You Track Sleep?

Many fitness trackers record your sleep. When they do, they generally watch for movement using a three-axis accelerometer to a more sensitive degree than they do during the day. Some devices report graphs showing the times when you were in light sleep and deep sleep based on motion.

There are also dedicated sleep trackers out there that attach to your mattress, like the SleepAce RestOn. But we haven't found them to offer an appreciable advantage over wrist-based trackers, which have the advantage of doing a lot more than simply tracking your rest. If you don't like the idea of wearing something on your wrist to bed and need a new mattress, you can always spring for the Eight Smart Mattress.

Go Sport-Specific

Swimmers will want a waterproof tracker, but keep in mind that not all water-safe trackers actually track swimming. Runners will probably want a watch that shows time, distance, pace, and lap time, at the very least. If you want good accuracy for those metrics without having to carry a smartphone, you need a runner's watch with built-in GPS, such as the Garmin Forerunner 735XT. For more, see The Best Fitness Trackers for Running.

Also consider the display. Otherwise excellent devices like the Fitbit Charge 2 have screens that turn off after a few seconds. If you want to see your stats at all times, or simply use your tracker as a wristwatch, look for one with an always-on display. How you control the tracker is also important. If you like to run in the cold while wearing gloves, you may want to steer clear of devices that only have touch-enabled displays.

Cyclists have even more considerations. There's a difference between tracking how many miles you pedal and calories you burn versus monitoring your power and cadence. If all you want is the former, you can find a few fitness trackers that support bicycling as an activity. More serious cyclists will want a device that can pair with additional bike equipment, like a cadence sensor, and should look at devices from sport-specific companies, like Garmin, Mio Global, and Polar.

The App Experience

A fitness tracker's app matters. Whether on your phone or on the web, the app is absolutely vital because it is where you make sense of the information the tracker collects. Fitbit has one of the best apps and websites we've tested. It lets you record all kinds of data that many other companies don't, such as calories consumed, allergy severity, and stress level.

Fitness

If you want total body analysis, look for a system that incorporates a smart bathroom scale. Fitbit, Polar, and Withings and do. Check out the Fitbit Aria 2, the Polar Balance, and the Withings Body Cardio. These send your weight directly to your account, so you can't cheat the system by entering a lower number. The QardioBase 2 is another top choice, especially for pregnant women.

Smartwatch vs. Fitness Tracker

Several fitness trackers have some smartwatch functionality, and some smartwatches have fitness features, too. The Fitbit Versa comes close to blending both worlds, but at the moment it still lags far behind the Apple Watch in terms of third-party app support.

The Apple Watch Series 4 places more of an emphasis on health and fitness tracking than any other smartwatch we've seen. It even has an FDA-approved electrocardiogram (ECG) function that generates a PDF of your heart rhythm you can share with your doctor, which is a feature you won't find on any of trackers listed here. But as its name implies, it's first and foremost a smartwatch. See our list of The Best Smartwatches for recommendations in that category.

Other Options

With so many good fitness trackers on the market right now, and promising ones on the horizon, it's hard to contain them all in just one list. We've limited our picks here to trackers that have scored four stars or higher, but there are lots of other very good options out there that might be right for you. We update this list often, so make sure to check back for our latest recommendations. And for the very latest reviews, see our Fitness Trackers product guide.
