OTO takes a fundamentally different approach to fertility support by combining continuous physiological monitoring with personalized, science-backed guidance.
Unlike many fertility apps that rely on calendar tracking or self-reported data, OTO uses real-time biometric insights captured through its wearable biosensor. This allows OTO to understand your body’s current state—rather than making predictions based only on past trends.
With this data, OTO delivers:
Personalized daily activity plans tailored to your physiological readiness
Actionable stress and recovery guidance based on your nervous system and cardiac signals
Objective insights that complement how you feel, helping you make more informed decisions
By addressing both lifestyle factors and biological readiness, OTO provides a truly data-driven approach to fertility—helping you optimize your body’s conditions in a way that adapts to you in real time.
