About Fitness Trackers

Fitness trackers range from slim bands that count steps and sleep to full GPS watches for runners and swimmers. Most people wear them every day, so comfort and battery life decide whether the tracker stays on your wrist.

Accuracy also varies by activity. Wrist heart rate is fine for steady exercise but less reliable during intervals or weight training.

How to choose a fitness tracker

What you'll track

Step and sleep tracking is available on almost any band. Runners and cyclists benefit from built-in GPS; swimmers need water resistance rated for swimming.

Battery life

Simple bands last one to two weeks. Smartwatches with bright screens may need charging every day or two.

Heart rate accuracy

Optical sensors work best when the band sits snugly above the wrist bone. For serious training, a chest strap paired to the tracker is more accurate.

Phone compatibility

Some watches only work fully with one phone platform. Check compatibility before buying.

Subscriptions

Several brands put detailed insights behind a monthly plan. Check what the free app shows.

Answers

Fitness Trackers: common questions

What is the best fitness tracker to buy?

One of our strongest picks is the Fitbit Charge 6 Fitness Tracker, a standout in our Best Fitness Trackers for Running list. The Garmin Vivosmart 5 is another excellent choice.

How do I choose the right fitness trackers?

Start with your main use and budget, then compare our shortlists: Best Fitness Trackers for Running, Best Fitness Trackers for Seniors, Best Fitness Trackers for Sleep Tracking.

What should I look for when buying fitness trackers?

Step and sleep tracking is available on almost any band. Runners and cyclists benefit from built-in GPS; swimmers need water resistance rated for swimming.

Does the Amazfit Band 7 really last 18 days on a charge?

Close to it under moderate use. In testing with the always-on display disabled, occasional workout tracking, and continuous heart rate monitoring, the battery lasted 15 to 17 days before needing a charge. Enabling the always-on display or using GPS-connected workout tracking daily shortens this noticeably, closer to 9 to 11 days, which is still well above most competitors.

Does the Amazfit Band 7 have built-in GPS?

No, it uses connected GPS through a paired phone via the Zepp app. This works for tracking route and pace during runs or rides as long as the phone is nearby, but there's no standalone GPS chip for phone-free route tracking, similar to the Garmin Vivosmart 5's approach.

Is the Zepp app good for tracking long-term trends?

It covers the basics, daily steps, sleep, heart rate, and workout history, clearly enough, but it's less polished than Fitbit's or Garmin Connect's apps for surfacing long-term trends and insights. Data is all there, but you'll do more manual scrolling and tapping to find historical comparisons than with the more mature competing apps.

Is Alexa built into the Amazfit Band 7 actually useful?

It's a nice bonus rather than a core reason to buy. Alexa on the Band 7 can answer quick questions, set timers, and check weather via voice command, all useful for a quick glance-free interaction. It requires a Wi-Fi connected phone nearby and isn't as fast or fully featured as Alexa on a dedicated smart speaker, but it's a genuinely uncommon feature at this price point.

Which has better battery life, Amazfit Band 7 or Samsung Galaxy Fit3?

The Amazfit Band 7, with an 18-day rating that held up to 15-17 days in real-world testing, versus the Galaxy Fit3's 13-day rating which held up to 11-13 days. The Band 7 wins by roughly 4-5 days of real-world battery life, a meaningful gap for anyone who wants to minimize charging.
