Garmin CIRQA FCC Filing Reveals Whoop Rival Smart Band

FCC filing IPH-04378 confirms Garmin is building a dedicated fitness band called the CIRQA. The documents point to a Whoop-style recovery tracker with WiFi, Bluetooth Low Energy, and almost certainly ANT+, which is standard across Garmin's lineup.

The SAR reports and antenna specs buried in the filing suggest a compact, screenless or minimal-display form factor. That puts it squarely against the Whoop 4.0 and Fitbit Charge 6, not against Garmin's own Fenix or Forerunner series.

ANT+ support matters here. It means the CIRQA could pair directly with Garmin's existing ecosystem of chest straps, power meters, and bike sensors, something Whoop still refuses to do. That alone gives endurance athletes a reason to pay attention.

WiFi on a fitness band is also telling. Continuous background sync without draining a paired phone's battery is the obvious use case, and it suggests Garmin wants this device logging data passively around the clock, much like Whoop's always-on HRV and recovery scoring.

No pricing or release date yet. But if Garmin prices this under the Whoop subscription model and leans into ANT+ integration, it could pull real numbers from the recovery-tracking crowd. Worth watching.
