California-based diabetes software nonprofit Tidepool is working with smart ring maker Ōura to build a dataset for diabetes research.

Finalnd-based Ōura contributed its third-generation Ōura Ring devices and memberships to Tidepool, which will seek to create one of the most comprehensive multi-modal real-world datasets assembled in diabetes to date.

Participation in the research initiative will be limited to individuals who opt in through Tidepool, which will pair biometric data from Ōura Ring – sleep, activity, heart rate, temperature trends and menstrual cycles – with diabetes device data, including continuous glucose monitors (CGMs) and insulin pumps.

The result will provide researchers with a dataset to accelerate the development of clinical guidelines, diabetes technology and personalised care models.

“For too long, diabetes research has overlooked critical physiological factors that impact health, especially for women,” said Kelly Watson, vice president at Tidepool. “This collaboration with Ōura is a pivotal step towards closing that gap and unlocking new avenues for innovation. By creating a dataset of this scale and detail, we are giving researchers the tools they need to answer long-overdue questions and, ultimately, reduce the daily burden of diabetes.”

This collaboration reflects a shared commitment to advancing equitable health research through responsible data collaboration and exemplifies how cross-sector cooperation can accelerate scientific understanding of women’s health, exercise and diabetes.

Recruitment is expected to launch in early 2026 through an IRB-approved study. By opting in to this study, participants consent to sharing their data with Tidepool’s Big Data Donation Project, where data are de-identified and, with participant consent, shared with academics, researchers and industry innovators to accelerate diabetes research.

“Our mission is to empower individuals to take proactive ownership of their health, and we’re proud to support Tidepool in extending that mission to the diabetes community,” said Shyamal Patel, senior vice president at Ōura (ouraring.com). “The resulting dataset will provide the scientific community with a new foundation for understanding how biometric trends intersect with diabetes management. We believe this collaboration will not only fuel ground-breaking discoveries but also empower individuals with a more complete picture of their health, changing the landscape of diabetes management.”

Founded in 2013, Tidepool (tidepool.org) is a nonprofit specialist in diabetes software working to reduce the burden of living with diabetes by making data more accessible, actionable and meaningful. Tidepool develops open, interoperable tools for people with diabetes and the health systems that serve them, including Tidepool+, Mobile, Uploader and Loop.
