Ultrahuman launches Ring PRO in Singapore at S$679 with up to 15-day battery and no mandatory subscription

Ultrahuman launched its flagship Ring PRO in Singapore on October 14, priced at S$679, and said the device offers up to 15 days of battery life with no mandatory subscription. The company confirmed the ring goes on sale in local stores and online from that date.

The Ring PRO is available in physical retail at Takashimaya and Sprint‑Cass and online through Shopee and Lazada, and comes with a one-year warranty. Ultrahuman said the ring ships with the PRO Charging Case as part of the purchase and that a pop-up kiosk for sizing will operate at Takashimaya until October 21.

Ultrahuman states the ring lasts up to 15 days on a single charge and that the PRO Charging Case extends combined battery life to more than 45 days. The company said the ring can store up to 250 days of health data on the device itself, increasing to up to a year when used with the case, reducing the need for constant phone syncing. Charging uses a magnetic click‑in system that Ultrahuman says generates less heat than conventional wireless charging to protect the battery over time; the case also works on any Qi wireless charger and includes a built‑in speaker to aid location via the app.

The Ring PRO collects heart rate, heart rate variability, skin temperature and movement continuously, and records sleep stages and timing overnight to produce a Sleep Index and a Recovery Score each morning. Ultrahuman said the Recovery Score updates through the day as movement, naps and breathing exercises change the picture. During daytime the device tracks activity, stress and circadian rhythm, including how far a wearer’s sleep and wake times drift from their natural pattern, and the company’s AI platform Jade aggregates those readings into personalised guidance.

On the hardware side, Ultrahuman described a dual‑core processor that runs machine learning on the ring itself and a redesigned heart‑rate sensor housed in a titanium unibody. The product includes a ProRelease feature that allows the ring to be safely cut off if a finger swells or is injured. The Ring PRO is offered in Bionic Gold, Space Silver, Aster Black and Raw Titanium and in sizes 5 to 13.

Ultrahuman said sleep, recovery, movement, stress and circadian tracking are included with the ring while optional add‑ons called PowerPlugs extend tracking capabilities; some PowerPlugs are paid. PowerPlugs listed by the company include Caffeine Window, which suggests when to have caffeine and when to stop to protect sleep; Smart Alarm, which wakes the wearer during light sleep once a sleep goal is met; and Social Jetlag, which measures the gap between weekday and weekend sleep schedules.

Additional PowerPlugs described by Ultrahuman are Respiratory Health, built with Sleep Cycle, which detects snoring and coughing overnight and shows their effect on heart rate and HRV with all audio processed on the phone; Phase Alignment, which times daylight, exercise and wind‑down to the wearer’s circadian rhythm; Vitamin D, which estimates how long it is safe to spend in the sun; and Cycle & Ovulation, which predicts a seven‑day fertile window. Ultrahuman said Cycle & Ovulation Pro confirms ovulation with more than 90 per cent accuracy.

Ultrahuman was founded in 2019 and is based in Bengaluru, with Mohit Kumar as co‑founder and CEO, and the company said it has more than 700,000 users in over 100 countries. The firm noted that TIME named it among the World’s Top HealthTech Companies in 2025 and 2026, and that its wider product range includes the Ring AIR, the Blood Vision testing service, the M1 Live continuous glucose monitor and Ultrahuman Home. Ultrahuman’s global Ring PRO launch in February excluded the United States after an October 2025 US International Trade Commission ruling in Oura’s favour in a patent dispute that blocked Ultrahuman from importing new rings into the country.

A pop‑up kiosk at Takashimaya runs from October 14 to 21 where visitors can try the Ring PRO and receive sizing; the PRO Charging Case is included with the S$679 purchase.
