I Tested EVERY Fitness Tracker (Don't Make This Mistake)

Overview

The reviewer wore six screen-free trackers for a month: Google Fitbit Air, Amazfit Helio Strap, Polar Loop, Garmin Cirqa, Hume Band 2.0, and Whoop 5.0. He compared heart-rate tracking against a Polar H10 chest strap, examined 21 nights of sleep data, tested step counting, and measured battery life. No overall numerical ratings were given.

Main findings

Design, comfort, and charging

• Fitbit Air was the smallest, thinnest, and lightest, packing many features into a compact body.
• Whoop 5.0 had the best clasp: it was easy to adjust and convenient to put on and take off. The reviewer liked the other trackers’ Velcro straps less.
• All could be worn on the wrist or bicep. The reviewer preferred the bicep for a less noticeable fit, though it takes some getting used to.
• All were described as waterproof and comfortable enough to largely forget once accustomed to wearing them. The reviewer questioned the need to shower with them, since charging provides an opportunity to take them off and wet straps can be uncomfortable.
• Charging is generally magnetic; Garmin uses a cable that plugs directly into the device. Whoop’s portable battery pack can charge it while it is being worn.
• Fitbit, Helio, Garmin, and Whoop have vibration motors for notifications and alarms. Polar and Hume do not.

Heart-rate accuracy during workouts

Hume’s workout feature was still in beta, so it was excluded from the comparison. Its workout heart-rate data also could not be exported cleanly, as Apple Health readings were fragmented.

• On the wrist: Whoop was the most consistent against the Polar H10, with Fitbit and Helio close behind. Polar generally performed reasonably well but sometimes lagged or missed peaks. Garmin’s wrist results were more erratic and often missed peaks.
• On the bicep: Garmin ranked first, followed by Whoop, Helio, Fitbit, and Polar. The reviewer noted that these results were less consistent than in his previous testing.
• Apple Watch comparison: The newly tested Apple Watch models produced heart-rate data that looked nearly identical to the chest strap in the final workout. Among the fitness bands, Garmin performed better on the bicep than on the wrist.
• The reviewer personally preferred bicep wear for discretion, despite several trackers generally producing stronger results on the wrist.

Sleep tracking

Across 21 nights, the devices broadly agreed on basic sleep duration and timing when the reviewer slept normally. They differed more on nights when he woke repeatedly and in their sleep-stage estimates. The reviewer considered sleep stages less important than basic sleep measures.

Reported averages:

Measure Results Bedtime Whoop 12:25; Fitbit 12:32; Helio 12:41; Garmin 12:52; Polar 12:55 Wake time Polar 8:00; Garmin 8:05; Whoop and Helio 8:33; Fitbit 8:34 Total sleep Hume 7h44m; Whoop 7h25m; Fitbit 7h23m; Helio 7h14m; Garmin 6h46m; Polar 6h35m Deep sleep Whoop 2h16m; Garmin 1h53m; Fitbit 1h28m; Helio 1h19m; Polar 1h06m REM sleep Fitbit 1h55m; Helio 1h53m; Whoop 1h38m; Polar 1h24m; Garmin 1h16m Light sleep Fitbit and Polar 4h each; Helio 3h48m; Garmin 3h36m; Whoop 3h31m Time awake Whoop 43m; Fitbit 32m; Polar 30m; Garmin 27m; Helio 22m

Polar and Garmin each once treated a nighttime wake-up as the final wake-up. Whoop had one notably high outlier for time awake.

Sleep heart-rate and breathing-rate readings were fairly consistent across devices. HRV varied substantially. Because different brands calculate HRV differently, the reviewer cautioned that values are best compared over time on the same device, not between devices.

Hume’s sleep page was especially limited: it showed total duration and a sleep-stage graph, but not time spent in each stage or clear bedtime and wake time. Hume also lacked many of the sleep-specific metrics the reviewer wanted to compare.

Apps, activity, and recovery

• Whoop: The home screen emphasizes sleep, recovery, and workload, alongside health and stress monitoring, activity, alarms, a recovery diary, goals, and dashboards. The reviewer praised its sleep and recovery detail and overall app experience.
• Helio: Offers sleep, recovery, and workload indicators, as well as activity and training suggestions, steps, calories, stress, and a “hybrid charge” recovery measure. The reviewer called its training plan useless for this tracker.
• Fitbit/Google Health: Offers many metrics, a chronological daily view, workout shortcuts, and a weekly cardio score the reviewer liked because it is an average rather than a daily goal to hit.
• Polar: Presents activity, cardio status, steps, calories, workouts, readiness, and sleep metrics across several pages. Its app has no subscription.
• Garmin: Shows sleep score, Body Battery, training readiness, HRV status, training status and load, and customizable metric views. The reviewer liked its longer-term HRV history and baseline information.
• Hume: Uses a health indicator and “metabolic pulse” (described as an indicator related to healthy aging), along with metabolic capacity, workload, recovery, and a “My Day” summary. The reviewer disliked the prominent Hume Plus offers.
• Activity summaries and workout reports include measures such as heart-rate zones, workout duration, training load, steps, and calories. Whoop has no separate activity page, but provides activity and stress information and post-workout reports.

Step-count test (1,000 steps counted by hand):

Tracker Count Helio 1,009 Hume 1,041 Garmin 1,043 Fitbit 1,066 Polar 1,138 Whoop 467 on one test; 661 on a repeat

The reviewer found the non-Whoop trackers generally capable as pedometers, though Polar overcounted more. Whoop’s step counting was a major weakness relative to its price and strong workout heart-rate results.

Other features

• Five of the six trackers reportedly offer an AI coach that can access device data.
• Four track stress; the reviewer said he rarely uses that feature.
• Four have vibrating alarms. Some offer smart wake timing, while others sound at a set time.
• Garmin and Polar have powerful web apps for examining and accessing data.
• Biological-age-related features include Garmin Fitness Age, Hume’s Metabolic Pulse, and Whoop Age.
• Whoop offers a detailed HYROX workout library and a recovery diary for tracking habits.
• Fitbit is said to track irregular heart rhythms.
• Blood-pressure tracking was mentioned for Hume and Whoop, but Whoop requires its most expensive Life subscription for the feature.

Battery life

All trackers exceeded their advertised battery claims in the reviewer’s test.

Tracker Advertised Tested Fitbit Air 7 days 8.5 days Helio Strap 10 days 12.3 days Garmin Cirqa 10 days 13.3 days Polar Loop 8 days 16.5 days Whoop 5.0 14 days 17.9 days Hume Band 2.0 14 days 22.1 days

The reviewer was pleased with all of them, noting that screen-free trackers last far longer than smartwatches. Longer or more frequent workouts will reduce battery life. Hume’s battery percentage behaved unusually during testing: it dropped quickly at first, then stabilized and later showed an unexplained increase.

Price and subscriptions

• Fitbit Air and Helio Strap: $99 each as a one-time purchase. Optional subscriptions add features, but core data remains available without them.
• Polar Loop: $200, with no subscription.
• Garmin Cirqa: $200, with optional Connect Plus features; core metrics are not subscription-locked.
• Hume Band 2.0: $249, with an optional subscription. The reviewer considered the price difficult to justify given the other trackers’ data and app experience, and disliked the app’s frequent subscription offers.
• Whoop: Requires an annual subscription: One costs $199/year, Peak $239/year, and Life $359/year. Over three years, those plans total $597, $717, and $1,077, respectively. The reviewer strongly disliked that stopping payments blocks access to the app and data, effectively making the device unusable.

Verdict

• Best overall / premium experience: Whoop 5.0. It offered excellent wrist heart-rate accuracy and the reviewer’s favorite app experience, but had poor step counting and by far the highest long-term ownership cost.
• Best value recommendation: Fitbit Air. At $99, it is exceptionally compact, delivered strong heart-rate results, and offers good data without requiring a subscription.
• Other standouts: Helio performed well in wrist heart-rate tests and is inexpensive. Garmin was best on the bicep and offers extensive training and recovery information. Polar requires no subscription and delivered long battery life, but lagged on some workout peaks and overcounted steps.
• Least compelling at its price: Hume. Its $249 price, limited sleep and workout data presentation, beta workout tracking, and intrusive app offers made it less compelling, despite its longest tested battery life.

Overall, Whoop may suit someone prioritizing the app and training and recovery experience. The reviewer found Fitbit Air difficult to pass up for its price and compactness.

Speaker perspective

The video presents one reviewer’s testing and opinions. He generally praised Whoop’s app and wrist heart-rate accuracy, preferred Fitbit as a value option, and criticized Whoop’s subscription lock-in and step counting. He also favored wearing trackers on the bicep for discretion, while acknowledging that several devices performed better on the wrist.
