RingConn 3 impresses on looks, falls short on health tracking

A TechCrunch review of the RingConn 3 found the screenless health-tracking ring’s design compelling but its core health-tracking promise unconvincing enough to send it back. The reviewer bought the ring — starting at $349, compared with the $399 starting price of the rival Oura Ring 5, which also requires a $6 monthly subscription on top of the hardware purchase — and returned it roughly 10 days later, within the product’s two-week return window.

On build quality, the review was largely positive. The RingConn 3 matches the Oura Ring 5’s 2.3-millimeter thickness and, in its brushed-metal finish, felt more scratch-resistant than some other buyers’ online reports suggested. Users are sent a sizing kit before the ring ships, which the reviewer found necessary since it required a larger ring size than expected. The company claims a 14-day battery life per charge; the reviewer did not use the device long enough to confirm that figure but reported no battery issues during the roughly 10-day test period. The ring is water-resistant enough to wear swimming, though the reviewer opted to remove it before showers.

The appeal of a screenless design lines up with a broader shift in the category: American spending on fitness trackers grew 88% year-over-year, largely driven by screenless wearables like the Oura ring and the Whoop wristband, according to market research firm Circana.

In practice, the review found the RingConn 3 required more manual intervention than expected — it only detects a workout if the wearer is physically moving through space, missing stationary activities like gym sessions or Pilates while flagging brief walks as workouts. The reviewer had hoped the ring’s headache-detection feature, which supposedly warns of oncoming migraines by monitoring heart rate variability, would prove valuable given a history of unpredictable migraines. About a week into ownership, the reviewer suffered what they described as the most severe migraine attack of their life, lasting an entire weekend — while the ring’s app reported they were in “top form” throughout. That failure was decisive in the decision to return the device.

Why it matters

The review underscores a gap between screenless wearables’ polished hardware and their still-unreliable predictive health claims — a distinction that matters as spending on the category accelerates.
