We compared 5 current fitness trackers on real specs, sensors and hidden subscription costs, from the budget Galaxy Fit3 to the membership-only WHOOP 5.0, to help you pick the right one.
For most people who want steps, sleep and heart rate without a screen full of menus, the Fitbit Charge 6 is the easiest all-around pick thanks to built-in GPS and Google Maps/Wallet, though its deepest insights sit behind an optional Premium subscription. If long battery life and a no-nonsense design matter more than smartphone extras, the Garmin vivosmart 5 is still a solid, still-current choice, though Garmin has been signaling a successor for over a year and hasn't shipped one as of this writing. Buyers chasing serious recovery and strain data should know upfront that the WHOOP 5.0 is not a simple one-time purchase: Amazon and every other retailer sell it bundled with a required annual or monthly membership, and the hardware stops functioning without an active plan. The Samsung Galaxy Fit3 and Amazfit Band 7 round things out as budget-friendly, subscription-free options for anyone who just wants the basics tracked reliably.

Buyer checklist
This guide is desk research, not a hands-on lab test: we did not physically wear or test these trackers. Instead we verified that each product has a real, currently active Amazon.com listing with a genuine ASIN (cross-checking against the manufacturer's own site and other major retailers like Best Buy, Target and Walmart where Amazon's page couldn't be fetched directly), then compared their publicly documented specs side by side, including display type, sensors, battery life, GPS implementation, water resistance and whether ongoing app or membership subscriptions are required versus optional. Where different retailers or product-year variants listed slightly different battery-life numbers, we've noted the discrepancy rather than picking whichever figure sounded best.
It depends on the device. The Samsung Galaxy Fit3 and Amazfit Band 7 work fully with free apps and no subscription. Fitbit Charge 6 and Garmin vivosmart 5 track steps, heart rate and sleep for free, with an optional paid tier (Fitbit Premium/Google Health Premium, or Garmin Connect+) unlocking extra AI insights. WHOOP 5.0 is different: the hardware itself only works with an active paid WHOOP membership, so there's no way to use it as a one-time purchase.
Only the Fitbit Charge 6 has a built-in GPS chip that can log a workout route without your phone nearby. The Garmin vivosmart 5, Samsung Galaxy Fit3 and Amazfit Band 7 all rely on 'connected GPS,' meaning they borrow your phone's GPS signal during a paired workout. WHOOP 5.0 has no display and no independent GPS tracking at all; it estimates activity from motion and heart-rate sensors rather than mapping a route.
Probably not for most casual buyers. Every WHOOP 5.0 listing we found, on Amazon, Best Buy and Dick's Sporting Goods, sells the device bundled with a required 12-month (or monthly) membership, and the band itself has no screen or standalone mode; it simply stops delivering data if the membership lapses. If you specifically want deep strain, recovery and HRV coaching and are comfortable with an ongoing subscription cost (WHOOP's standard plans run roughly $199 to $239 per year, or about $30 per month), it can be worthwhile. If you just want a one-time purchase, the other four trackers here are better fits.
