How does OvuFirst work?
1 Get started
Apply the OvuFirst sensor under your arm or on your wrist overnight, using our specially designed OvuFirst arm or wristband. Your Ovufirst sensor measures your skin temperature continuously every 5 minutes. We recommend the under arm application for maximum accuracy. With no radio waves transmitted from the sensor while applied to your body, OvuFirst is completely safe to use.
2 Sync your device
Remove and clean the OvuFirst sensor before downloading its data to the OvuSense App in the morning. Data are uploaded to a secure cloud database ensuring your information is safe.
3 Record your data
Using your current cycle data generated from the OvuFirst sensor, your OvuSense App provides live updates and plotting your own unique cycle pattern.
Proven in side by side trials with our OvuCore technology, the OvuFirst sensor provides the information to your OvuSense App to confirm your fertile window with over 90% accuracy, and predict when you'll be at your most fertile in your next cycle.
