We’ve seen trackers for a woman’s cycle, but Ava is the first wearable designed to predict a woman’s fertility.



“It should be simpler,” says the promotional video for Ava, which begs the question: isn’t it?

For the uninitiated among us [writer included] baby making is apparently not the easy path we presume it to be. Despite humanity making it thus far without any problems, as it turns out, family production can be challenging.

Who knew?

Ava promises to not only make getting pregnant easier but to also help would-be-mommies track other health data with a little thing called science. Actually, it’s technology, but that’s an applied science so it counts.

The promise



Shaped like most fitness and health trackers, except that the business end of this one looks like a cell dividing, Ava is built much like its promise. It’s simple.

You will have your best chance of getting pregnant quickly with Ava.

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.

The logic: Many new families are limited on time. Knowing the best to time to try is a convenience, reducing worry, pressure, and yeah, fighting.

The Ava team doesn’t specifically promise all of that, but shoppers can do the math. If you know anyone who’s tried to get pregnant, you know it can be stressful.

All that it does



Ava not only identifies five days of fertility, it tracks other health features valuable to would-be mothers.

Resting pulse rate is tracked in beats per minute, so mom knows if her heart is healthy. Ava tracks skin temperatures too. This data can determine if the sleeping environment is too warm or too cool.

Variability of heart rate is also measured, as is Mom’s quality of sleep. Both have an impact on fertility. Ava even tracks the wearer’s breathing rate, movement, heat loss, and something called perfusion.

These are all wrapped into the bigger picture of Mom’s health. The best thing about all of these metrics is, they’re all collected while she sleeps.

How it works



After a year of clinical study in Zurich, at the university hospital, Ava was determined to be 89% accurate in predicting fertility. The front line science team produced a paper which is to be peer reviewed and published by year’s end.

The simple explanation for how Ava knows when the wearers are fertile is the culmination of the metrics listed above. The team at Ava collaborated with scientific experts on these points of information to derive how and when each could indicate fertility.

Would be mothers wear the device when sleeping, then port the device into their smartphone in the morning. The software for Ava analyzes the collected information, identifying if it is a good day for fertility or not.

All that’s left to do at that point is, well, you know…

Ava is an FDA approved device. You don’t need a doctor’s prescription to buy it.

While it may not be the sexiest wearable we’ve covered, it’s certainly beats peeing on ovulation sticks to determine fertility.

Yeah, that’s how it was done previously. Every day, the woman would pee on a stick, examine it, then announce her results.

Not the sexiest image before engaging in, well…
