I manually counted 5,000 steps to test the Apple Watch 11 vs Fitbit Air, and Apple wins the accuracy battle while offering superior elevation data

Apple Watch Series 11 or Fitbit Air, which popular wearable is the more competent/reliable fitness tracker? I decided to find out by performing one of my renowned head-to-head walk tests.

For this showdown, I wore the Apple Watch 11 on my left wrist and the Fitbit Air on my right wrist for a 5,000-step walk around beautiful Seattle, Washington. How do I know it was 5,000 steps? I counted every darn one, with some assistance from my trusty tally counter (one click= 100 steps).

Now, if I were a betting man (I’m not), my money would be on the Series 11 to come out victorious. Not only is it one of the best smartwatches in 2026, but it’s also four times the cost of the Fitbit Air: $399 vs $99.

Then again, the Fitbit Air may be affordable, but it’s also one of the best fitness trackers in 2026. Not only that, when I pitted in a separate walk test versus the Apple Watch SE 3, the Air surprisingly came out victorious. Will this be a repeat win? Read on!

When it comes to wrist-based trackers, the Fitbit Air and Apple Watch 11 couldn’t be more different. The former has no screens, buttons, or notifications, and lasts up to a week.

The Series 11, meanwhile, is a super-connected device, boasting a large, bright touchscreen, multiple physical buttons, and compatibility with a dizzying array of apps. That said, the Series 11 comes up short on battery life; 24 hours per charge is the norm.

Another major difference: the Fitbit Air has no onboard GPS for location tracking or altimeter for elevation data, so you need to carry a smartphone along when logging an outdoor workout. The Apple Watch 11, on the other wrist, has both GPS and an altimeter.

With that out of the way, let’s move on to the results!

Before we begin, it’s worth noting that Strava appears to have had a “hiccup” while recording this walk test. How do I know? The app logged just 4,506 steps, which is a major red flag. Normally, Strava’s step-count data is within 10-20 steps of my actual count. TLDR: Take Strava’s distance, climb, and pace data with a grain of salt.

Anyhow, both the Apple Watch 11 and Fitbit Air performed admirably when it came to keeping an accurate tally of my steps — anything within ~150 steps of the control is considered excellent in my book — but the Apple Watch was just a little closer!

Distance data between the Apple Watch and Fitbit Air is similar enough for my liking. The Fitbit noted slightly more ground covered but also a faster pace, which checks out.

The Fitbit Air’s elevation metric is concerningly inaccurate (this walk was particularly hill-heavy), which doesn’t make a whole lot of sense, given the device can piggyback off of the iPhone 16 Plus’s climb data. This also isn’t the first time I experienced less-than-precise elevation tracking insights from the Fitbit Air; it was also way lower than expected versus the Apple Watch SE 3.

Fortunately, the Fitbit Air finishes strong: Heart rate data is a perfect match with the Apple Watch Series 11, a result I love to see. Meanwhile, the Air logged slightly more calories burned, but used way less battery during my ~42-minute stroll.

Apple Watch 11 vs Fitbit Air: Winner

Ultimately, the Apple Watch Series 11 wins this showdown of fitness tracking accuracy against the Fitbit Air, with a more precise total step count and climb data.
