This source's evidence 🎬

Source verdict

The reviewer highlights that the Garmin Cirqa offers the comprehensive health and fitness metrics of a high-end Garmin watch, all accessible through the Garmin Connect app and without requiring a subscription for core features. He finds the hardware design practical, being small and waterproof, though notes the use of a Gen 4 optical heart rate sensor instead of the newer Gen 5.

About this source

This review provides an initial hands-on look at the Garmin Cirqa, a screenless wearable. It covers the device's hardware, including its design, sizes, colors, and waterproof rating, and delves deeply into the Garmin Connect app's features and how the Cirqa integrates with it for tracking various health and fitness metrics.

Review notes

The Garmin Circa provides a comprehensive health and fitness tracking experience despite its lack of a screen, making it a strong contender for those seeking discreet monitoring. It offers the same advanced metrics as higher-end Garmin watches, including sleep score, body battery, and training readiness, all accessible through the robust Garmin Connect app. However, it uses a Gen 4 optical heart rate sensor instead of the newer Gen 5, which might have minor accuracy differences in edge cases, and lacks medically certified ECG. If you prioritize detailed Garmin ecosystem metrics in a screenless form factor without a subscription, this device is an excellent choice. If medically certified ECG or the latest heart rate sensor technology are crucial, other options might be more suitable.

  • Activity alerts are only time-based

Structured claims

The Garmin Cirqa is priced at $199 and does not require a subscription for its core functionalities, such as tracking metrics and recording activities. Only structured workouts require Garmin Connect Plus.

Evidence items

Garmin Cirqa Pricing and Subscription Status

The band features a detachable pod, which can be removed by pressing small pins on the side. This allows for band removal and access to the pod itself.

Gen 4 Optical Heart Rate Sensor

specification_claimneutralt=01:57–02:22

The pod's back includes a standard Garmin charging connector and a Gen 4 optical heart rate sensor. The reviewer notes that while it's not the latest Gen 5 sensor, it's generally fine for most accuracy scenarios.

Gen 4 Sensor Performance and Features

expert_opinionneutralt=02:05–02:37

The reviewer states the Gen 4 sensor is "basically fine" for most accuracy scenarios, with differences from Gen 5 only in a handful of edge cases. It has skin temperature tracking but lacks medically certified ECG, which Gen 5 typically includes.

Size Comparison to Competitors

comparisonneutralt=02:40–02:55

The Cirqa pod is described as "pretty darn small" compared to the Whoop Band and Fitbit Air. It's about the same size as the Whoop Band (possibly 1mm wider) but the Fitbit Air Band is "quite a bit smaller."

Device Weight

The device weighs 20 grams. The reviewer mentions he will provide more comparison information later.

Waterproof Capability Demonstration

hands_on_demopositivet=03:13–03:27

The Cirqa is waterproof to 50 meters. The reviewer confirms using it in a pool with "no problems at all," stating he's in the water virtually every day.

Garmin Connect App 'Essentials' Tab

hands_on_demoneutralt=04:24–04:54

The Garmin Connect app features a new 'essentials tab,' available to all Garmin users, not just Cirqa. This tab displays a customizable set of four metrics: sleep score, body battery, training readiness, and HRV status.

Training Readiness and Detailed Metrics

hands_on_demoneutralt=04:54–05:54

The Circa includes training readiness, a cornerstone of Garmin's training platform. Metrics contributing to this score include sleep score (e.g., 77), recovery time (e.g., 11 hours), HRV status (e.g., balanced), acute load (e.g., optimal zone), recent sleep, and stress scores. These are the same metrics found on high-end Garmin watches.

Structured Workouts Require Connect Plus

reviewer_claimneutralt=06:17–06:33

Structured workouts are the only feature mentioned that requires a Garmin Connect Plus subscription. All other functionalities, including monitoring and recording, are available without it.

Smart Alarm Functionality and Button Control

hands_on_demoneutralt=06:40–07:29

The device offers smart alarms, which can wake a user within a 30-minute window based on sleep stages. The physical button can be tapped once to snooze the alarm or long-held to dismiss it entirely.

Manual Activity Start/Stop Button

hands_on_demoneutralt=08:29–09:07

The small button on the side of the pod can be configured to act as a start/stop button for a predefined activity, such as cycling or strength training. This is particularly useful for activities that are hard for automatic detection.

Heart Rate Broadcasting Feature

hands_on_demoneutralt=09:33–10:04

The Cirqa allows for heart rate broadcasting by long-holding the button. This enables other apps, like Exift, to pair with the device as an ANT+ or Bluetooth Smart heart rate sensor.

Automatic Workout Detection

reviewer_claimneutralt=10:48–11:57

The Circa can automatically detect certain workout types, such as running and walking. After an automatically detected workout, the device will prompt the user to confirm the activity type in the app.

Manual Workout Initiation

hands_on_demoneutralt=11:58–12:35

Workouts can be manually initiated by pressing the physical button on the side of the device. This action triggers a notification in the Garmin Connect app, allowing the user to resume or end the activity.
