Best Fitness Tracker (2026): 7 Picks by Battery and Price

The Charge 6 is Google's current Fitbit band, and the only one here with built-in GPS and GLONASS, so it can track a run or ride without your phone nearby, per Google's spec sheet. It also supports Google Wallet over NFC, letting you tap to pay without a phone or card.

Google rates the battery at up to 7 days, though that's with some features turned down; running the always-on display or continuous SpO2 monitoring will use more power day to day. Deeper health insights, like the Daily Readiness Score, need a Fitbit/Google Health Premium subscription, which comes with a free trial at purchase.

Skip it if you don't want a subscription nudging you toward paid features. The Garmin Vivosmart 5 below gives you full functionality through its free app.

Garmin introduced the Vivoactive 6 as the direct successor to the Vivoactive 5, with a brighter AMOLED display and more than 80 preloaded sport modes, per Garmin. It lists up to 11 days of battery life in smartwatch mode, and includes Body Battery energy tracking, HRV status and sleep coaching, none of which require a subscription.

It sits closer to a GPS sports watch than a slim fitness band, so if you specifically want the smallest possible tracker, the Fitbit Inspire 3 or Garmin Vivosmart 5 below are a better fit.

Skip it if you want a thin, low-profile band rather than a watch-style face. The Garmin Vivosmart 5 covers most of the same health tracking in a smaller size, minus built-in GPS.

The Inspire 3 is Fitbit's simplest current band: no built-in GPS, no NFC payments, just a color AMOLED touchscreen, continuous heart rate and an SpO2 sensor in a slim case. Google rates its battery at up to 10 days, noticeably longer than the GPS-equipped Charge 6.

It uses connected GPS through your phone rather than its own chip, so runs still get mapped, just with your phone along for the ride. Google also committed to 2 years of security updates after the device's last sale date, matching its policy across the Fitbit lineup.

Skip it if you want GPS tracking without your phone, or tap-to-pay. The Fitbit Charge 6 adds both for a bit more size and cost.

The Vivosmart 5 pairs Garmin's health tracking, including Body Battery energy monitoring, stress tracking and sleep insights, with the free Garmin Connect app and no subscription requirement. Garmin rates battery life at up to 7 days in smartwatch mode.

It's worth a caution: the Vivosmart 5 launched in 2022, and several retailers now list it as discontinued or out of stock, while unconfirmed reports point to a possible newer Vivosmart model. If you want this exact one, check that the listing you're buying is in stock and sold as new.

Skip it if you want a device you're confident will be Garmin's current model for years to come. The Vivoactive 6 is a safer long-term bet, in a larger, watch-style case.

Samsung initially planned to skip a US launch for the Galaxy Fit3, then reversed course and brought it to the US in January 2025. It has a 1.6-inch AMOLED display in an aluminum body, Samsung lists up to 13 days of battery life, and it tracks heart rate, SpO2, sleep and snoring through the free Samsung Health app, with no subscription required.

Like most bands in this price range, it relies on a connected phone's GPS rather than its own chip, and it skips NFC payments entirely. It pairs most tightly with a Samsung phone; some Samsung Health features work differently or not at all on other Android phones.

Skip it if you don't own a Samsung phone. Samsung Health's deeper features are built around Samsung's own ecosystem, so a Fitbit or Garmin band may integrate better with an iPhone or non-Samsung Android phone.

The Band 7 is built around battery life: Amazfit lists up to 18 days of typical use and up to 28 days in a battery-saving mode, well beyond any Fitbit or Garmin band here. It has a 1.47-inch AMOLED display with an always-on option, 24-hour heart rate and SpO2 monitoring, and more than 120 sport modes.

It also builds in Alexa for voice requests, unusual at this price, and uses Zepp, Amazfit's own free app, with no subscription. The trade-off is a smaller brand ecosystem than Fitbit or Garmin, and no NFC payments.

Skip it if brand ecosystem and app polish matter more to you than battery life. The Fitbit Inspire 3 has a more established app and service behind it.

The Smart Band 9 is sold on Amazon as a global-version import rather than through an official Xiaomi US store, which is worth knowing before you buy, since warranty support may work differently than with a US retail product. It has a 1.62-inch AMOLED display, 5 ATM water resistance, and reports suggest around 21 days of typical battery life.

Xiaomi has already released a newer Smart Band 10 in other markets, but it wasn't turning up as a US-purchasable listing at the time of writing, so the Band 9 remains the current Xiaomi option available here. It runs through the free Xiaomi Wear or Mi Fitness app, with no subscription required.

Skip it if you'd rather buy from a brand with an official US retail presence and support. The Amazfit Band 7 or Fitbit Inspire 3 are both sold through more conventional US retail channels.
