World's first AI saliva hormone tracker
One drop of saliva. Forty minutes later, your estrogen trend, fertile window, and cycle day are in your app — no strips, no refills, no guesswork.
Three steps, one drop
Open your device and wait for the indicator light to flash once.
Use your finger to place one drop of saliva on the lens, then close it. No refills, no special procedure.
In about 40 minutes your result lands in the Ovul app over WiFi — you don't wait around.
A proven method, made effortless
As estrogen rises before your fertile window, your dried saliva forms fern-shaped crystals — a method recognized since the 1950s and traditionally read under a microscope. Ovul brings it home: lens, camera, and AI trained on more than 30,000 real ferning images.
