Fertility monitors, from the maker's own page.

Six products already in this directory, checked October 15, 2026. The order is not a ranking. Each row is limited to the price, the sample, the hormones, and the app or subscription the company actually published.

How we chose

What had to be on the company's own site.

A product is here when it is already listed under fertility in this directory and its own site states what it measures. Urine hormone monitors are Mira, Inito, Oova, and the Clearblue touch-screen monitor. Proov is a urine kit the company says can confirm ovulation, not a reusable reader. Tempdrop is a wearable thermometer the company sells as a fertility monitor. If a page did not print a dollar price, the price cell says so.

Questions these pages can answer.

Do these monitors diagnose infertility or PCOS?

No. Mira's site says its results are for hormone monitoring and cycle tracking, and are not intended to diagnose, screen for, or indicate PCOS or any other medical condition. A hormone number or a temperature is one reading from that product.

Which of these measure progesterone?

Inito and Oova say they measure PdG, a urine metabolite of progesterone. Mira's Ultra4 wands include PdG. Proov's homepage discusses progesterone and PdG and says its test is FDA-cleared to confirm ovulation. Tempdrop measures overnight temperature and does not test urine. Clearblue's touch-screen monitor measures estrogen and LH, not PdG.

Can the Clearblue Fertility Monitor be used as birth control?

Clearblue says the Fertility Monitor and its test sticks are for women trying to conceive and should not be used as a method of contraception.
