A Week-Long Sleep Duel: Fitbit Air Outpacing Whoop MG for Everyday Sleep Insights
A reviewer tests the Fitbit Air on the wrist against the Whoop MG on the bicep for a week; after initial calibration, Fitbit Air’s total sleep times align closely with Whoop, though deep sleep and REM readings still diverge. The Fitbit app delivers quicker, clearer sleep summaries and a better everyday user experience, suggesting that for basic sleep insight the $100 Fitbit Air offers most of the value, while Whoop’s ECG and recovery features justify the premium only if those extras matter.
