Ava Fertility Tracker

Whether you’re struggling to conceive or just starting on the journey to conception, Ava helps you achieve your baby goals faster than other methods.

Properly timing intercourse can double a woman’s chances of conception,1 but as many as 75% of couples get that timing wrong.2 Why? Because the fertile window is more than ovulation day. It’s also the 5 days leading up to it, with peak fertility 2 to 3 days before ovulation.

Ava is clinically proven to identify your unique 5-day fertile window as it’s happening—letting you know when you’re ready to conceive up to 4 days earlier than LH tests, and with 50% more precision than the calendar method used by typical period-tracker apps.3

Go beyond ovulation. Take control of your cycle and make every fertile day count.

Syncs with iPhone and Android. Tested for cycles of 24 to 35 days. Not tested for PCOS.

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.

    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.

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

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

*12-months guarantee of pregnancy

A “12-month money-back guarantee” means you’re protected if you purchased the Ava Plus bundle, wore the Ava bracelet continuously for at least (1) year, and didn’t get pregnant during that time.

You’ll get a full refund if the following conditions are met:

  • Your Ava bracelet was shipped to you at least 12 and no more than 15 months ago.
  • You are the original purchaser of the Ava 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 period and the last day before the next period are within the 12-month timeframe of first using Ava.
  • In the unfortunate case of pregnancy loss, 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.
  • If above conditions are met and your Ava bracelet has been returned and received at our warehouse as instructed.
