In short

Get Ultrahuman Ring PRO for battery and storage: up to 15 days a charge, 250 days of data on the ring and a case that adds up to 45 days. It's $479, with no recurring fee for core data, in sizes 5 to 14. US orders are pre-orders shipping from 10 October 2026. Ring AIR is lighter and $349 but lasts 4 to 6 days.

Who it is for

  • Travelers and anyone who hates charging. Between the ring and its case, PRO can go weeks without a wall outlet.
  • Anyone who goes days without opening the app. PRO stores up to 250 days of data on the ring.
  • Anyone avoiding a membership. Ultrahuman says core ring data has no recurring fee, so the ring is a one-time purchase.
  • Ring AIR owners. Ultrahuman says PRO comes in the same sizes, so your AIR size carries over.

Who should skip it

  • US buyers who need a ring before 10 October 2026, when Ultrahuman's US pre-orders start shipping.
  • Anyone who'd rather have a lighter, cheaper ring. That's Ring AIR.
  • Anyone expecting every feature to be free. Cardio Adaptability ($24 a year) and Cycle & Ovulation Pro are paid PowerPlugs.

What sets it apart

  • Up to 15 days per charge.
  • A charging case in the $479 box that adds up to 45 days of battery.
  • ProRelease: Ultrahuman says the ring can be cut off more easily if your finger swells or is injured.
  • A dual-core processor with on-chip machine learning, and a redesigned PPG sensor.

Caveats

  • The US picture is muddled. Ultrahuman's February launch excluded the United States, yet an Amazon listing for one size was live on 22 September 2026, ahead of Ultrahuman's own US shipping.
  • Battery figures come from Ultrahuman's own test conditions, and it says results vary.

PRO or AIR?

PRO is Ultrahuman’s 3rd-generation ring, announced on 27 February 2026, and it trades AIR’s lighter build for endurance:

SpecRing PRORing AIR
Price$479$349
Thickness2.65 mm, varies by size2.4 mm
Weight3.3–4.8 g2.4 g
BatteryUp to 15 days4–6 days
Sizes5–14Same as PRO

Pick PRO if you’d rather charge every couple of weeks than every few days; pick AIR if weight and price matter more. Ultrahuman Ring AIR vs Ring PRO covers the rest.

The charging case

The included case does more than top up the battery. In Chill Mode it holds up to a year of ring data, the ring sits on UltraSnap magnetic DC pins inside it, and the case itself charges by Qi at 5W or over USB-C, with a Find My Case speaker to help you track it down.

Sensors and tracking

PRO pairs a redesigned PPG sensor with a temperature sensor and a 6-axis IMU, run by a dual-core processor with on-chip machine learning. Ultrahuman aims it at deep sleep, recovery and uninterrupted performance tracking; it isn’t a GPS sports watch. The Ultrahuman app gets Jade AI, and Ultrahuman calls the ring’s Bluetooth Low Energy 5.3 radio EMF-safe, which is its own claim.

Price and offers

PRO costs $479 in the US with the case included. On 19 September 2026, Ultrahuman’s US page also offered a trade-in credit of up to $115 and Klarna or Affirm split payments, shown as $120 a month. Offers change, so check Ultrahuman’s page before you buy.

Frequently asked questions

Can I get Ring PRO in the US now?

Not from Ultrahuman before 10 October 2026, when its US pre-orders start shipping. The Amazon listing that was live on 22 September 2026 is for Aster Black in size 9 (B0H1N3BNJ4), so check its seller and shipping date before you order.

Does Ring PRO need a subscription?

No. Ultrahuman says there's no recurring fee for core ring data, so you pay once for the ring. PowerPlugs are optional paid add-ons.

What's the difference between Turbo and Chill?

They're battery modes. Ultrahuman rates Turbo at about 12 days and Chill at more than 15, and the case's year of data storage applies to Chill Mode.

Does Ring PRO work with an iPhone?

Yes. The Ultrahuman app runs on iOS and Android, though Ultrahuman doesn't list minimum OS versions.
