Google's Fitbit Air is being positioned as a direct competitor to the Whoop 5.0, and MKBHD tests whether that claim holds up. The device is a screenless fitness band in the same category as Whoop: continuous health tracking, recovery scoring, and subscription-based data access. The question is not whether it tracks well, but whether it tracks better, or even equally, at a lower cost.
The review goes deeper than spec comparisons. MKBHD examines real-world accuracy differences in heart rate, sleep staging, and recovery metrics between the two devices worn simultaneously. Those side-by-side numbers are where the video earns its runtime, not in the unboxing.
Fitbit provided the unit to MKBHD directly, which is worth noting when weighing the tone of the conclusions. Whether the Air actually displaces Whoop depends heavily on what the subscription model looks like long-term, and that detail is addressed in the full video. If you care about screenless wearables or the subscription fitness tracking market, the data comparisons alone make this worth watching in full.
