REVELSTOKE, British Columbia , October 25, 2023 (press release) –

  • Cronometer releases a new Cycle Tracking feature, powered by ŌURA, to help track and analyze menstrual cycle data.

Today, ŌURA, the company behind Oura Ring, the revolutionary smart ring that delivers accurate, personalized health data, insights, and daily guidance into sleep, along with leading nutrition tracking app, Cronometer, have announced a partnership that will allow women to explore new insights in their reproductive cycle.

Building on the long-standing integration between the two apps, Cronometer has introduced a Cycle Tracking feature that leverages data from ŌURA's new Cycle Insights functionality. Cronometer users with a menstrual cycle using the latest version of the app can now view cycle day, body temperature variation, and cycle phase (luteal or follicular) along with helpful information about common symptoms in each cycle phase and suggestions for actions and habits that can help them feel their best.

Not only will women be able to view their cycle data from ŌURA on the Dashboard and the Diary pages within the nutrition tracking app, they will also have the ability to look back and see the cycle phase as an overlay in any chart, helping to identify trends across the two phases.

"We hope that this new feature unlocks a world of insights around women's health." says the CEO of Cronometer, Aaron Davidson, "Being able to chart and visualize the impact a cycle phase has on health data like nutritional intake, sleep, energy, mood and more will be eye-opening for women."

To leverage this data, users may create a chart showing overall calorie intake or drill down to any nutrient (like carbs, fat or even vitamin C) to see if a cycle phase has an impact on their diet. Cronometer allows for the ability to track additional metrics, such as exercise and sleep, which can also be compared against cycle phase data.

While the current iteration of the Cycle Tracking feature is only available to Cronometer users with an Oura Ring, the company has plans to allow the ability to self-report symptoms and phases, extending the feature to all Cronometer users in the future.
