Garmin Cirqa Filing: New Whoop-Beating Feature Listed
Garmin has filed a trademark application for Cirqa in Canada. The filing is mostly routine, but on closer inspection, a new feature stands out.
One phrase in the listed goods separates this filing from standard commercial protection: “measuring and analyzing recovery from physical and emotional stress, human alertness level, and performance”. Garmin’s existing stress metric is HRV-derived and does not distinguish between physical and emotional arousal. The Canadian filing deliberately separates the two, thus strongly suggesting new capabilities.
For the full picture of what Cirqa is expected to do and how it compares to Whoop and Fitbit Air, see the detailed Garmin Cirqa analysis.
Why is “emotional stress” the interesting part
The sensor used to measure emotional and cognitive stress is EDA (electrodermal activity, also known as the galvanic skin response, GSR). It works by detecting changes in skin electrical conductance driven by eccrine sweat glands activated by the sympathetic nervous system. Unlike optical heart rate sensing, which infers stress indirectly from HRV, EDA reads arousal state directly from the skin. FEDA/GSR sensors are not new to the market, and Fitbit did indeed build EDA into the Sense and Sense 2, but neither Whoop nor Garmin have ever implemented it.
If Cirqa incorporates EDA sensing, it would add a stress-monitoring dimension that no current-generation wearable from any brand offers.

What this might mean for the sensor stack
EDA is bioelectrical rather than optical, which means it requires direct contact with skin electrodes. It cannot sit inside an Elevate optical HR sensor. Three possibilities follow. Either
- Cirqa carries Elevate 5 alongside a discrete EDA sensor module,
- a next-generation Elevate 6 incorporates additional bioelectrical sensing with EDA as one capability among several, or
- ECG/EDA could be combined into one inner-surface electrode. Published research has demonstrated this.
An initial FCC filing analysis published here in February confirmed the presence of WiFi, BLE, and a skin-worn band format. It did not have any new insights into the sensor stack, so the Canadian filing is the first documentary signal of potentially new capabilities.
What the filing actually says
Canadian trademark application 2483360 was filed on June 19, 2026, by Garmin International Inc., with a priority date of February 25, 2026. USPTO application 99/670,310 was already in place before the March launch speculation. The status is formalised and awaiting examination, which is a normal state for a pre-release filing. Cirqa is listed under Nice class 9: wearable sensors for measuring and analysing physical and emotional stress, human alertness levels, and performance, also adding standard non-medical, non-therapeutic wording.
The bigger picture
The dates confirm Cirqa was a defined product by late February 2026, consistent with the Garmin Connect app code analysis and the regulatory filings across Singapore and the UAE that were covered earlier this year. The Canadian trademark signals Garmin is treating Cirqa as a near-live product being actively extended and protected across jurisdictions.
The filing does not confirm a launch date, a price, or a final sensor specification. What it does confirm is that Garmin’s stated ambition for Cirqa goes beyond replicating Whoop’s existing feature set. Whether that ambition is in the hardware or reflects Garmin’s broader platform positioning around stress and readiness, the competitive picture has just become more interesting.

Quick answers
What is EDA sensing?
EDA stands for electrodermal activity, also known as the galvanic skin response. It measures changes in skin electrical conductance caused by eccrine sweat glands activated by the sympathetic nervous system, making it a direct marker of emotional and cognitive arousal rather than physical exertion.
Does Whoop have EDA sensing?
No. Whoop does not currently include an EDA sensor. Fitbit is the only major wearable brand to have implemented EDA at consumer scale, in the Sense and Sense 2.
Could EDA and ECG share the same sensor on Cirqa?
Possibly. Both EDA and ECG require direct electrical contact with the skin, and published research has confirmed that the same electrodes can serve both functions in a single wearable. Garmin already uses skin-contact electrodes for ECG on the Fenix 8. A band format with inner-surface contacts could plausibly handle both modalities. This is inference, not a confirmed specification.
What does the Canadian trademark filing confirm about Cirqa?
It confirms Garmin is actively extending trademark protection into additional jurisdictions and that the product was defined by at least February 25, 2026. It does not confirm a launch date or final hardware specification.
Is EDA confirmed for Garmin Cirqa?
No. The inference comes from the goods description in the trademark filing, which distinguishes between physical and emotional stress sensing in a way that Garmin’s existing HRV-based metrics do not support. It is a reasonable inference from the language, not a confirmed specification.

Interesting tidbit. Does the EDA sensing require setting a baseline for a few days, or it starts working right away?
EDA sensor is also on the pixel Watch’s
Nice info – thanks
Just waiting for the launch date…
