Fitness Trackers Put to the Test: 5K Run and Step-Counting Showdown
Wearables from Google, Samsung, and Garmin have been put through their paces in a series of hands-on tests, revealing significant differences in how they track heart rate, GPS, and steps. The comparisons, conducted by fitness-focused journalists, offer a detailed look at the strengths and weaknesses of the latest devices.
5K Run: Heart Rate and GPS Deviations
In a recent test, an Android Central journalist ran the Emerald City 5K while wearing the Pixel Watch 5, Galaxy Watch 9, and Garmin Cirqa. The race was just over 5 kilometers (3.1 miles), and all three devices measured heart rate, but the Galaxy Watch 9 showed notable deviations from the other two.
The Samsung watch took nearly four minutes to catch up to the Cirqa and Pixel Watch in heart rate, then rose above both for more than 10 minutes. The journalist noted that their heart rate wasn't so elevated right at the start, suggesting the Galaxy Watch 9's readings were delayed or inaccurate initially. Later in the run, the Pixel Watch 5 and Garmin Cirqa diverged, with the Pixel Watch dropping to about 135 bpm while the Cirqa remained steadier. The Pixel Watch eventually caught up, and the two stayed in sync for much of the run, until the end when the Pixel Watch fell just below the Galaxy Watch 9 and Cirqa.
In a second, shorter run, the Galaxy Watch 9 again logged lower heart rate data throughout the 12-minute session, hinting at a persistent issue with its heart rate accuracy during exercise.
GPS tracking also varied by device. The Galaxy Watch 9 and Garmin Cirqa (via a connected phone) tracked the run route, but the Pixel Watch 5 did not record any GPS data. The journalist attributed this to a possible GPS connection issue before the run started.
Despite the heart rate and GPS hiccups, the Galaxy Watch 9 logged the closest distance to the official race distance of 3.146 miles: it recorded 3.15 miles. The Pixel Watch 5 logged 3.19 miles, and the Garmin Cirqa logged 3.29 miles.
Step Counting: 5,000-Step Walk
After the run, the same journalist walked 5,000 steps with each device and compared the readings to a manual count. The Garmin Cirqa was the most accurate, over-counting by just 12 steps. The Pixel Watch 5 over-counted by 26 steps, and the Galaxy Watch 9 over-counted by 79 steps. Notably, the Cirqa does not display a step count while tracking, so a midpoint figure was not available during the walk.
Separate Test: Garmin Cirqa vs. Apple Watch Ultra 3
In a separate comparison, Tom's Guide tested the Garmin Cirqa against the Apple Watch Ultra 3 over a 12,000-step walk. The Cirqa, priced at $199, is Garmin's first screenless tracker, positioning it against devices like the Fitbit Air and Whoop 5.0. The Apple Watch Ultra 3 costs $799.
Using a manual clicker from Amazon to count steps, the journalist split the walk into three segments. The Garmin Cirqa counted 103 steps more than the manual count, while the Apple Watch Ultra 3 missed 242 steps. The journalist customized the Cirqa's side button to start a walk, changing it from the default Timed Activity setting.
The Apple Watch Ultra 3 showed overall daily steps rather than per-workout steps, requiring a third-party app to see per-workout data. This could explain some of the discrepancy, but the Cirqa's closer count was still notable given its much lower price.
Recommendations and Takeaways
Based on these tests, the Android Central journalist recommends the Garmin Cirqa for low-key fitness tracking and the Pixel Watch 5 for a smartwatch experience. The Cirqa's accuracy in step counting and its screenless design make it a solid choice for those focused on basic fitness metrics, while the Pixel Watch 5 offers a more comprehensive smartwatch experience despite its GPS issue.
The tests highlight that fitness trackers can vary significantly in heart rate and GPS accuracy, and even the most expensive devices may not always be the most precise. For those considering a new wearable, these hands-on comparisons offer valuable insights into real-world performance.
