Ultrahuman Ring Pro: Smart Ring for Biohacking with Mixed Results

Ultrahuman has launched its latest smart ring, the Ring Pro, marketed as a response to the growing popularity of Oura Ring. However, the results are mixed: the device boasts improved specifications but sacrifices ergonomics. The ring is now 0.25mm thicker than its predecessor (2.65mm vs. Oura Ring 5’s 2.28mm) and weighs 0.9–2.4g more, which becomes noticeable during extended wear.

The Ring Pro’s standout feature is its battery life. The device operates for up to 15 days on a single charge, while the premium charging case provides an additional 45 days of power. This makes it ideal for travel or an active lifestyle. The Ultrahuman app has also been updated, now focusing on sleep, activity, and stress data, though it retains biohacking elements like caffeine intake and circadian rhythm recommendations.

Despite these improvements, the Ring Pro lags behind Oura Ring 5 in comfort and design. Users also report supply chain issues and inconsistent customer service, including delayed deliveries and unresolved complaints on forums. Ultimately, the choice between the two devices depends on priorities: opt for Ring Pro if battery life and no subscription matter most, or choose Oura Ring 5 for comfort and a sleeker form factor.
