Finally understand your body. Wear the Ava bracelet at night for effortless insight about your fertility, pregnancy, and your health.watch video
Understand how your cycle impacts your health with features like symptom tracking, trend analysis, graphs, and more. Trend analysis lets you see how your menstrual cycle impacts the way you feel throughout the month.
Tracks your sleep, physiological stress levels, and resting heart rate—so you can see whether your lifestyle is supporting optimal health.
There’s no need to take your temperature or pee on sticks. Just wear Ava when you sleep and sync when you wake up.
Real-time detection of fertile window
Ava is clinically proven to detect the very beginning of the fertile window—in real time, as it happens. That’s totally different than LH tests, which only detect the last day or two of the fertile window, and the temperature method, which only confirms ovulation after the fact.
Couples who time intercourse accurately double their chances of conceiving in a given month.
Ava is still there for you once you conceive. Once you get pregnant, get a whole new app experience with detailed explanations about what to expect in each week of pregnancy. You’ll be able to continue tracking your sleep, physiological stress, and resting pulse rate, as well as compare your weekly weight gain to standard recommendations.
For wherever you are in life
Track your cycle naturally
If you’re not using hormonal birth control, Ava provides a profound connection to your natural cycle, deepening your understanding of your body in a way that has never before been possible.
The Ava bracelet is a new way to find your fertile window. It’s easier to use and more accurate than other methods.
Track your health during pregnancy with continued monitoring of sleep, physiological stress, resting pulse rate, and weight gain. Get week-by-week content about your changing body and growing baby.
What makes Ava different?
Ava is the only device to use resting pulse rate along with other parameters to detect the fertile window in real time.
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.
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 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 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.

Received my bracelet in August and started using it immediately…first and second cycles it predicted my ovulation to be about a week later than I had been thinking…and guess what? I am now pregnant. On my SECOND CYCLE with the Ava bracelet. I’m officially a fan.Lizzie
I had migraine headaches randomly throughout the month. With Ava, I realized that I always get them like clockwork right after I ovulate. Ava didn’t solve my headaches (if only!) but it does help me be more prepared for them, so they never take me by surprise anymore.Nurit
