Cirqa Deep-Dive: Garmin’s Screenless Band Holds Its Own Across Wrist and Arm Tests
DC Rainmaker’s in-depth Cirqa review tests both wrist and bicep placements against Whoop 5.0, Fitbit Air, Amazfit Helio and Polar Loop across cycling, running, strength and sleep. The verdict is that heart-rate accuracy is generally solid but can falter in certain cold outdoor intervals; automatic workout detection has improved but Garmin still lags behind competitors in some scenarios. Sleep and daily activity metrics are broadly comparable to rivals, with bicep placement delivering higher workout HR fidelity and wrist placement better for sleep. Overall Cirqa is competitive and capable, but there are gaps in HR continuity and auto-detection to address.
