What makes Ava different?

  • Convenience

    Wear Ava while you sleep, and the rest is taken care of.

  • Real-time data

    Ava detects the fertile window based on real-time data from your body.

  • More time to conceive

    Ava is clinically proven to detect an average of five fertile days per cycle—giving you and your partner more flexibility around planning for babymaking.

  • Backed by science

    Ava was created by a team of doctors and researchers committed to advancing scientific understanding of the menstrual cycle. We don’t just make products, we conduct clinical studies and publish peer-reviewed papers.

  • For more than just getting pregnant

    In addition to your fertile window, Ava tracks your sleep, physiological stress level, and resting heart rate, providing a holistic understanding of your health.

Ava Reviews

Is Ava right for me?
The below is intended as a guideline. For more detailed questions about whether Ava is right for you, visit our FAQs and consult with your physician.

  • Yes: Your cycle is regular and between 24–35 days

    Ava will work with cycles slightly shorter or longer than the 28-day average, provided they are of consistent length.

  • Yes: You have endometriosis

    Ava can be used with endometriosis, unless there is severe scarring that interrupts ovulation.

  • Yes: You're using an alternate conception method

    Ava can be used to time conception methods other than intercourse, e.g. artificial insemination.

  • Yes: You’re breastfeeding

    Ava can be used while breastfeeding once your cycle has returned.

  • No: You’re taking hormonal birth control

    Ava works by sensing physiological changes related to your natural hormone levels.

  • No: You have PCOS

    Ava has not been tested with fertility conditions that interrupt ovulation, such as PCOS or hypothalamic amenorrhea.

  • No: Your cycle length varies significantly from month to month

    Ava has not been tested on women with irregular cycles that vary widely in length.

  • No: You're looking for contraception

    Ava has not been designed nor tested for pregnancy prevention.

1-year guarantee of pregnancy*
  • We strive to help our users to fulfill their dream of becoming pregnant faster and on their own terms, but unfortunately sometimes we are not able to. In the unfortunate event of unsuccessful tries over the course of a year we are offering a money-back guarantee for such cases.
  • 1-year guarantee of pregnancy means you’re protected if you wore the Ava bracelet continuously for at least one year and didn’t get pregnant during that time. You’ll get a full refund if the following conditions are met:
  • Your Ava bracelet has been shipped to you min. 12 months and max. 15 months ago.
  • You are the original purchaser of the Ava bracelet.
  • Ava has received your returned bracelet.
  • You haven’t become pregnant since you began using Ava (please note that while Ava cannot prevent miscarriage/pregnancy loss, these occurrences will not void this guarantee).
  • You have worn the Ava bracelet regularly. We require that you synced your Ava on average 80% of your cycle across all your complete cycles during the first 12 months of using Ava. A cycle is considered ‘complete’ when both the first day of your menses and the last day before the next menses are within the 12-month timeframe of first using Ava. In case of the unfortunate event of a pregnancy not carried to term, your time in pregnancy mode in the app will be regarded as one complete cycle. Days where Ava makes it impossible for you to wear your bracelet (e.g. during replacement shipping) or where you have technical syncing issues, count as synced days.
  • You allow the Ava Customer Success team to look into this data at the time you request a return.
