Fitbit Charge 6 Review: A Slim Tracker With Built-In GPS, Heart Rate and Google Apps

Not everyone wants a full smartwatch on their wrist. The Google Fitbit Charge 6 is a slim band that focuses on health and fitness tracking, then adds a few of the most useful Google features: Maps directions, tap-to-pay with Wallet and YouTube Music controls.

This review explains what it tracks, what the Google additions bring and where a subscription comes in.

Who it's for

• People who want detailed health tracking in a small, light device.
• Walkers, runners and gym users who'd like GPS and heart rate without a bulky watch.
• Anyone focused on sleep and stress, two areas where Fitbit is strong.
• Android and iPhone users alike.

What we liked

• Built-in GPS. Track the pace and route of a run, walk or ride without carrying your phone.
• More than 40 exercise modes, plus automatic exercise recognition.
• 24/7 heart rate. It also broadcasts heart rate to compatible gym machines, such as treadmills and ellipticals, so you see it live on the console.
• Useful daily scores. Sleep Score, a stress management score and Daily Readiness turn raw data into something you can act on.
• Smart Wake alarm. It wakes you at a lighter point in your sleep, near your set time.
• Google Maps on the wrist. Turn-by-turn directions during a run or ride.
• Google Wallet. Pay for a coffee without a phone or card.
• ECG app and health sensors, in a band that's comfortable enough to sleep in.
• Slim design. It sits flat under a cuff and doesn't get in the way.

What could be better

• Some features sit behind a subscription. The tracker includes a 3-month trial of the premium membership, which adds personalized coaching and deeper insights. After that, it's a paid extra. The core tracking works without it.
• A Google account is required to set up and use the device.
• YouTube Music controls need a YouTube Music Premium subscription, and the tracker doesn't store music itself.
• Small screen. A 1.04-inch display is fine for stats, less so for reading messages.
• It isn't a smartwatch. There's no app store, and notifications are basic.
• GPS shortens battery life. Expect to charge more often if you track outdoor workouts frequently.
• Feature availability varies by country, particularly for payments and the ECG app.

Key specs explained

• Active Zone Minutes: time spent in heart-rate zones that count as moderate or vigorous exercise.
• Daily Readiness: a score suggesting whether your body is ready for a hard workout or needs recovery.
• Built-in GPS: the tracker records location itself, without relying on a phone.
• ECG: an on-demand check of heart rhythm, for information only and not a diagnosis.

Tips for getting the most out of it

1. Wear it a finger-width above the wrist bone for better heart-rate readings.
2. Wear it to bed for a week to build a reliable sleep baseline.
3. Set up Google Wallet at home before you rely on it at a checkout.
4. Turn off always-on display to stretch battery life.
5. Decide on the subscription during the trial, based on whether you use the coaching.
