Ultrahuman's new ring add-on offers medical-grade ovulation tracking

Business Aug 15, 2025

Ultrahuman just launched Cycle and Ovulation Pro, a premium add-on for its Ring AIR wearable.
This new feature, following their viO HealthTech acquisition, brings smarter menstrual and ovulation tracking—think ovulation confirmation, early/late detection, plus mood and symptom logs for a fuller wellness picture.

The plug-in uses viO's OvuSense tech

The plug-in uses viO's OvuSense tech—a temperature-based algorithm developed over 15 years and trained on a dataset of over 260,000 cycles.
It tracks finger temperature through the ring and is designed for those with conditions like PCOS or endometriosis.

Cycle and Ovulation Pro is live in the Ultrahuman app

Cycle and Ovulation Pro is live in the Ultrahuman app at $3.99/month or $39/year across the US, UK, EU, Canada, and Australia.
It's a step up from their free version—offering medical-grade insights that go way beyond basic period apps.
