You can start using your OTO sensor at any point in your cycle—there’s no need to wait for a specific phase.
OTO focuses on your current physiological state, using real-time data to provide personalized insights and recommendations. This means it can begin guiding you right away, regardless of where you are in your cycle.
Why Doesn’t Timing Matter?
Rather than relying only on calendar-based predictions, OTO continuously measures how your body is functioning. This allows it to:
Adapt to your body’s day-to-day changes
Provide guidance based on real-time readiness, not just cycle timing
Help you build a more complete picture of your patterns over time
What Should I Expect When Starting?
When you first begin using OTO:
Your data will become more personalized over time as patterns develop
You can start following your daily recommendations immediately
Consistency with assessments will help improve the accuracy of your insights
You can start anytime. The sooner you begin, the sooner OTO can start learning from your data and supporting your fertility journey.
