What makes Ava different?

  • It’s smart

    Ava is the only device to use resting pulse rate along with other parameters to detect the fertile window in real time.

  • It’s convenient

    With Ava, there’s no need to make any special effort to track your cycle. Just wear it while you sleep, and the rest is taken care of.

  • It gives you more time

    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.

  • It's 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.

  • It’s real-time

    Unlike the temperature method, which only tells you after you’ve ovulated, Ava detects signs that the body is preparing to ovulate up to five days in advance.

  • It provides health insight

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

    I finally received this bracelet back in September and now I’m 2 months pregnant. The bracelet timed my ovulation to be later than expected. My husband and I are very excited!

    I have been using the Ava since in received it and I love it. I believe it has been 3 months now and it is so interesting to watch it change as it understands my body more and more last month. I can tell by the way it fluctuates the ovulation dates after it has received my data for the night that it is doing its job. I can’t wait to get pregnant so I can show my friends what an amazing product this is.

    Ugh, I’ve tried every OPK out there. I’ve been TTC for five years with no results. This is the first time I’ve felt like I actually have a chance of catching my window at the right time! I travel for work frequently, so my husband and I are on a time crunch when it comes to getting the deed done and then hoping for the best. This has made everything much easier (and more romantic, lol) so far. I’m really grateful.
