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

The flagship smart ring is on sale at Takashimaya, Sprint-Cass, Shopee and Lazada from October 14, with a try-on pop-up at Takashimaya until October 21

Ultrahuman has launched its flagship Ring PRO in Singapore at a recommended retail price of S$679, with up to 15 days of battery life and no mandatory subscription.

The ring is on sale from October 14 in stores at Takashimaya and Sprint-Cass, and online through Shopee and Lazada. It comes with a one-year warranty.

Buyers who want to try the ring before purchasing can visit a pop-up kiosk at Takashimaya, open until October 21, for sizing.

A battery built around a charging case

Ultrahuman claims the Ring PRO lasts up to 15 days on a single charge, which it calls the longest in its category.

The ring ships with the PRO Charging Case, which the company says extends the combined battery life to more than 45 days. The ring can store up to 250 days of health data on its own, rising to up to a year with the case, so it does not need to sync with a phone constantly.

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 has a built-in speaker to help locate it through the app.

What the Ring PRO tracks

The ring monitors heart rate, heart rate variability, skin temperature and movement through the day and night.

Overnight, it records sleep stages and timing, producing a Sleep Index and a Recovery Score each morning. The recovery score updates through the day as movement, naps and breathing exercises change the picture.

During the day, it tracks activity, stress and circadian rhythm, including how far a wearer’s sleep and wake times drift from their natural pattern. Ultrahuman’s AI platform, Jade, pulls those readings together into personalised guidance.

Under the hood, the Ring PRO has a dual-core processor that runs machine learning on the ring itself, and a redesigned heart-rate sensor housed in a titanium unibody. A feature called ProRelease allows the ring to be safely cut off if a finger swells or is injured.

It comes in four colours — Bionic Gold, Space Silver, Aster Black and Raw Titanium — and in sizes 5 to 13.

No subscription, but optional add-ons

Sleep, recovery, movement, stress and circadian data are all included with the ring, and Ultrahuman says users keep full ownership of their health data.

That sets it apart from its biggest rival. Oura charges a membership of US$5.99 a month for full access to its ring’s features.

Ultrahuman does sell optional add-ons, which it calls PowerPlugs, to extend the ring’s tracking. Caffeine Window suggests when to have caffeine and when to stop to protect sleep, Smart Alarm wakes the wearer during light sleep once a sleep goal is met, and Social Jetlag measures the gap between weekday and weekend sleep schedules.

Respiratory Health, built with Sleep Cycle, detects snoring and coughing overnight and shows their effect on heart rate and HRV, with all audio processed on the phone. Phase Alignment times daylight, exercise and wind-down to the wearer’s circadian rhythm, while Vitamin D estimates how long it is safe to spend in the sun.

For women’s health, Cycle & Ovulation predicts a seven-day fertile window, and Cycle & Ovulation Pro confirms ovulation with more than 90 per cent accuracy, according to Ultrahuman.

Some PowerPlugs are paid add-ons rather than free features.

The company behind the ring

Ultrahuman was founded in 2019 and is based in Bengaluru, with Mohit Kumar as co-founder and CEO. The company says it has more than 700,000 users in over 100 countries, and that TIME named it among the World’s Top HealthTech Companies in 2025 and 2026.

Alongside the Ring PRO, its range includes the cheaper Ring AIR, the Blood Vision testing service, the M1 Live continuous glucose monitor and Ultrahuman Home.

The Ring PRO’s global launch in February excluded the United States. In October 2025, the US International Trade Commission ruled in Oura’s favour in a patent dispute, blocking Ultrahuman from importing new rings into the country.
