The Modern Fertility iOS App

Free

Note: Unfortunately, our app is not able to take new users at the moment. You will still be able to track ovulation with the Modern Fertility Ovulation Test without the app.

The ovulation detective

Follow your hormones

The Modern Fertility Ovulation Test measures luteinizing hormone (LH) in your urine. Why LH? The brain triggers an LH surge before you ovulate, making it an excellent predictor of ovulation. The app scans and logs your Ovulation Tests so you can catch your LH surge and your 2 most fertile days.

Get answers you can trust

The Modern Fertility Pregnancy Test is 99% accurate at detecting pregnancy from the first day of your missed period1 — but you can start testing as early as 6 days before. Track your cycle (and test results) with the app and get a countdown for the best days to test.
