the Garmin CIRQA Band Review
Garmin CIRQA Band was tested across six separate heart rate sessions, plus sleep, steps and calories. Here's what held up and what didn't.
On the wrist, it was good in three quite different situations. In a HYROX gym simulation it matched Whoop, Amazfit Balance 3 and Fitbit Air within about a beat, despite several stations involving tight gripping that should restrict blood flow to the wrist. In a flow yoga session it matched four references within a beat despite extreme positions held for 'long' periods. In an outdoor bike ride it matched a Tymewear VitalPro chest strap within about a beat across 5,311 matched data points.
It failed badly in two situations, both involving fast changes in effort or motion. In an open water swim it under-read by 20 to 30bpm against three other devices worn correctly under a wetsuit, its worst result by far. In a running interval session it underestimated heart rate at the start of four of five reps, off by roughly 9 to 10bpm, the largest error of any device in that test.
Moving the band from wrist to biceps and repeating the interval test fixed it completely: it matched an HRM 600 chest strap, a Polar Sense and a wrist-worn Whoop within half a beat each. Same sensor, same person, same interval structure. Only the wear position changed. That reflected consistently better sports performance on the biceps as expected.
Sleep tracking held up reasonably well against an Eight Sleep Pod 5 over 15 nights, resting heart rate and breathing rate in particular. Sleep stage breakdown showed no consistent pattern against any comparator, which is typical of wrist-worn sleep tracking generally rather than a CIRQA-specific issue. Step counts ran consistently high in controlled 500-step tests, on both the wrist and the biceps.

ISeems pretty good for most of its intended purposes?
