Apple Watch Series 12 Matches Garmin Readiness at 7/10 After 7-Night Calibration

Summary
After seven nights of baseline calibration, Apple’s new Vitals app produced its first Readiness score of 7/10, matching Garmin Cirqa’s 70/100 verdict that the wearer was generally ready but not fully primed.
Sleep scores diverged sharply at first—Apple logged 93 versus Garmin’s 62 on night one—but the two devices mostly tracked the same weeklong pattern, including a midweek dip and stronger final nights.
The biggest unexplained gap came on night six, when Garmin scored sleep at 87 and Apple at 68, underscoring how individual nightly readings can still vary even when broader trends align.
A Terra study of 77,000 nights across six wearable brands found trackers often converge on duration and general trends, while sleep-stage estimates such as REM and deep sleep can differ by hours because of different sensors and algorithms.
The comparison suggests Apple’s first Readiness feature is directionally consistent with established rivals, but daily scores remain estimates best read as trends rather than precise measures.
