How OvuSense works...

OvuSense App and Sensor
  • OvuSense has two parts: medical-grade Sensor and App.
  • The OvuSense Sensor fits comfortably in your vagina, similar to a tampon, and is worn while you sleep.
  • It takes a reading of your 'core body' temperature every 5 minutes, to build up an extremely accurate picture of your cycle.
  • In the morning, remove the Sensor and download your data to your mobile device.
  • The OvuSense App encrypts your data and uploads it to a secure cloud database, keeping your information safe.
  • FREE Fertility Nurse consultation for every OvuSense user,
  • and 7 days a week customer support.
