Fitbit vs Garmin
Two evenly matched everyday bands, compared: which one suits you comes down to subscriptions, GPS and how much polish you want.
Fitbit and Garmin dominate the fitness-band world, but they aim at different buyers. To keep this concrete we compare two directly matched everyday bands: the Fitbit Charge 6 and the Garmin vivosmart 5. Both track 24/7 heart rate, sleep and workouts in a slim, comfortable package, and both cost about the same — so the decision is really about philosophy.
Fitbit optimizes for approachability: a bright color touchscreen, a genuinely easy app, and headline features like built-in GPS and an FDA-cleared ECG app that the vivosmart lacks. The price of that polish is Fitbit Premium, the subscription that unlocks Fitbit’s most detailed sleep and health analysis. Garmin takes the opposite stance: the vivosmart 5’s display is a basic monochrome OLED and it leans on your phone for GPS, but everything it measures — Body Battery, stress, Pulse Ox — is free forever in Garmin Connect. Below is the short answer, a side-by-side matrix, and who each band is really for.

Frequently asked questions
Is Fitbit or Garmin better for beginners?
Fitbit is generally easier for beginners, thanks to the Charge 6's color touchscreen and a simpler app. Garmin's vivosmart 5 is still approachable but shows more data on a plainer display. If you want the gentlest learning curve, Fitbit has the edge.
Does Garmin require a subscription like Fitbit Premium?
No. Garmin Connect is free, so the vivosmart 5's Body Battery, stress and Pulse Ox data cost nothing beyond the device. Fitbit puts its most detailed sleep and health analysis behind paid Fitbit Premium, though new devices include a trial. This is often the deciding factor.
Which has better battery life, Fitbit or Garmin?
The Fitbit Charge 6 and Garmin vivosmart 5 are similar, both rated at up to about seven days. Real-world life drops if you use built-in GPS on the Fitbit or run always-on features. Neither is a multi-week band; for that, look at budget models like the Amazfit Band 7.
Does the Fitbit Charge 6 have built-in GPS and ECG?
Yes. The Charge 6 has built-in GPS to map workouts without your phone and an FDA-cleared ECG app in the US, plus SpO2. The Garmin vivosmart 5 has neither built-in GPS nor ECG and uses your phone's GPS. Where present, ECG is a wellness screening feature, not a diagnosis.
