Kyri Cycles

The Kyri and Cycle Tracking app are your new cycle BFF. Made by women for women, take control of your flow, improve your body literacy, and learn to work with your cycle.

Our entire user experience is built around you and your cycle, with our Kyri ring collecting your Heart Rate, Heart Rate Variability, and Basal Temperature for an easy insight into recovery and cycle information.

Say goodbye to period apps that play the guessing game, our Kyri ring tracks your basal temperature with over 15,000 overnight measurements to give you accurate insights into what your cycle is actually doing.

Please note, as of 2025, without the Kyri ring your app will not be useful to you. To purchase your Kyri, please head over to www.kyricycles.co
