"I'm not super into tracking things, but this is easy enough that I actually keep up with it. That says a lot."
Leah Warden · Verified buyer
"Not gonna lie, I was confused the first couple of days. But once you get it, it's actually really cool. I like that it connects estrogen to what I'm feeling, not just dates."

Before you add to cart
Yes, Ovul is ideal when trying to conceive. It's a digital ovulation tracker and hormone tracker device that helps identify your most fertile days by monitoring saliva changes.
Yes. Ovul's AI learns your unique estrogen patterns, detecting shifts that urine strips often miss with irregular cycles and PCOS — and it's especially helpful during perimenopause.
No, Ovul is not FDA approved as a contraceptive. However, it can help women practicing natural family planning (NFP) by showing fertile and infertile phases.
You're covered by the 6-month money-back guarantee: if Ovul does not help you better understand your cycle, return it for a refund of the device. Membership charges are non-refundable. Use Ovul at least 22 days a month so the AI has enough data to learn your pattern.
