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.
-

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

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

The wrist-worn device identifies fertile days. The average is identified as five per cycle, which is about two more than most other methods. This nearly doubles the wearer's chances to conceive.
Rather than only looking at a single factor of ovulation, like a urine ovulation test or the basal thermometer, the Ava has sensors that track nine different biological parameters.
The wrist-worn device identifies fertile days. The average is identified as five per cycle, which is about two more than most other methods. This nearly doubles the wearer's chances to conceive.
Even if you're not thinking about starting a family anytime soon, knowing when you're fertile can be a really empowering thing.
Unlike many other fertility trackers, its makers say Ava can tell you when you're most fertile in real time, while most methods that use temperature and cycle-tracking alone work only in retrospect.
- 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.
