After taking on Whoop, Garmin could come for Oura with its own smart ring — and as a Garmin fan, these are the 3 features I want to see

Garmin has apparently filed documentation for a smart ring
It seems to be carrying over the Cirqa branding from the fitness tracker
The device could potentially launch in the coming months

It seems Garmin is on a tear when it comes to expanding its range of fitness wearables: having challenged Whoop with the launch of the screenless Cirqa band in July, it's now apparently mulling over taking on the likes of Oura with its very own smart ring.

As per an Indonesian certification filing spotted by the rumor site Garmin News, the proposed smart ring would carry on the 'Cirqa' branding. It's categorized as a 'fitness product', and is a strong sign that a Garmin smart ring is coming — though not quite a guarantee.

Garmin has previously played down the idea of launching a smart ring to go with all of its smartwatches, but it seems something may have now shifted. It's not clear exactly when we might see the Cirqa smart ring, but a launch within a few months seems likely if the rumor is true; according to Garmin News, upcoming devices 'usually show up in database approvals right before manufacturing'.

The smart ring market is certainly a competitive one, with the recent launches of the Oura Ring 5 and the Ultrahuman Ring Pro. There have also been persistent rumors that Apple might eventually launch a smart ring to go alongside the Apple Watch.

What I want to see

I already have a Garmin Instinct 3 Solar which I love, for the breadth of its tracking features and the excellent battery life (the solar aspect helps here). If Garmin gets it right with the Cirqa ring, I could be tempted to invest in another fitness wearable.

First and foremost, it has to be thin and light enough that I forget I'm wearing it. As great as my Instinct 3 is, it is bulky, and it's not particularly comfortable to wear during strenuous exercise or while sleeping (I tend to use my phone as a sleep tracker instead).

Secondly — and apologies for being very predictable here — it has to offer excellent battery life. Smart rings work best when they're worn constantly. This is an area Garmin has done well in historically, so I'm quite confident here.

Thirdly, I'd like to see it offer as full a range of features as possible, without a Garmin Connect+ subscription. The subscription has already caused enough controversy, and if too many of the Cirqa smart ring features are paywalled, it'll be a no thanks from me.
