How Ava works
There are six days a cycle when it’s possible to conceive. Ava is clinically tested to recognize five of them. It's easy.Overnight, the Ava sensor bracelet collects continuous data while you sleep.
In the morning, sync your bracelet to the app, and Ava’s algorithm instantly shows your results.
Ava pinpoints your five best days to try for a baby as they're taking place.
At work while you sleep
For consistent readings, the Ava sensor bracelet goes to work overnight while your body is at rest.
As it records your physiological parameters, it also tracks movement with a built-in accelerometer. This signal allows it to measure your sleep quantity (duration) and quality (percentage of combined deep and REM sleep).
