The Bottom Line:  Our review of the Inito fertility monitor found it to be an excellent choice for those who want to quickly and conveniently measure hormones and track fertility. Inito offers lab-grade accuracy and results as fast as 10-minutes for actionable data (so to speak).

Inito Tracker basics

Inito tracker can help identify the perfect time

Infertility affects one in six people worldwide. As prospective parents, we struggle to conceive for various reasons, including age, health issues, or hormonal imbalances.

When we’re trying to conceive (TTC), accurately tracking fertility windows becomes crucial for increasing our chances of getting pregnant. That’s where Inito, a fertility monitor that measures multiple hormones, comes into play.

Inito offers us a unique approach to fertility tracking, providing accurate and personalized results. In this article, I will explore the benefits of using Inito, its features, and how it stands out from other fertility trackers on the market.

Inito Pros/Cons

Lab-grade accuracy: Inito measures four essential fertility hormones, providing a comprehensive picture of your cycle and accurate information about your fertility window.

Real-time data: Unlike many other ovulation trackers that only provide a yes or no answer, Inito provides actual numerical values for your hormone levels, which can be particularly helpful for people with irregular cycles or conditions like PCOS.

Easy to use: Collecting a urine sample and reading the results with the Inito app is a straightforward process that can be easily done at home.

Measures all necessary hormones: Inito measures Estrogen, LH, PdG, and FSH, giving you a complete picture.

Inito Fertility Monitor Review

Your personalized fertility tracker

Here are some of the highlights of using Inito’s Fertility Monitor:

Know your fertility hormone levels

Inito’s Fertility Monitor tracks estrogen, luteinizing hormone (LH), progesterone metabolite PdG, and follicle-stimulating hormone (FSH). Monitoring these hormones provides insights into your menstrual cycle and ovulation. 

Test on the right days

Inito’s Fertility Monitor offers personalized guidance on when to test based on individualized hormone variations, ensuring that you don’t miss any critical fertility signs.

It uses artificial intelligence (AI) to analyze your hormone data and predict the best days for testing. You’ll also receive reminders and alerts to stay on track. 

Know when you’ve successfully ovulated

After detecting when you’ve ovulated successfully, Inito’s Fertility Monitor will send you an alert and identify the best days to have intercourse. It measures your LH surge, a signal that ovulation is about to occur — so you’ll know when it’s time to get busy in the bedroom! 

Identify your full 6-day fertile window

Inito’s Fertility Monitor monitors multiple hormones to identify your full six-day fertile window, giving you more opportunities to conceive. Knowing your full fertile window can be especially helpful for those with irregular menstrual cycles.

What Inito Measures

Inito measures several hormones that help track fertility

Inito’s Fertility Monitor measures four hormones on a single test strip: Estrogen, luteinizing hormone (LH), progesterone metabolite PdG, and follicle-stimulating hormone (FSH).

Let’s take a closer look at each hormone and what it means for your fertility: 



Estrogen is the primary female sex hormone and plays a crucial role in regulating the menstrual cycle. It helps to thicken the uterine lining in preparation for implantation and supports the growth and development of ovarian follicles.

Luteinizing hormone (LH)

LH is a hormone that surges just before ovulation and signals to the ovary to release an egg. Inito’s Fertility Monitor measures beta LH, which doesn’t cross-react with other hormones and provides more accurate results than other ovulation tests.

Follicle-stimulating hormone (FSH)

FSH stimulates the growth and development of ovarian follicles. Inito’s Fertility Monitor tracks your FSH levels to identify any underlying fertility issues, such as ovarian reserve or premature ovarian failure. 

Progesterone metabolite PdG

Progesterone is essential for pregnancy. After ovulation, the corpus luteum (the remains of the follicle that released the egg) produces progesterone to prepare the uterus for implantation.

Inito’s Fertility Monitor measures PdG, a metabolite of progesterone excreted in the urine. Elevated levels of PdG in the 7-10 days after ovulation correlate to higher chances of a successful pregnancy.

Accuracy of Inito

Inito might be most accurate fertility tracker

Inito offers several features that make it one of the most accurate fertility trackers on the market, including the following:

Real-Time Data

Ovulation predictor kits (OPKs) and other fertility trackers on the market lack the numerical, real-time data needed to accurately track fertility, leading to missed peaks and false positives.

Furthermore, most ovulation tests only give “yes/no” results, which can be inaccurate and misleading, especially if you have irregular cycles.

Inito provides actual numerical values of your fertility hormones, allowing you to track your fertility more precisely.

Personalized Results

Most ovulation kits have a set value or a threshold, making them likely to give a false read if your hormones fall outside the average range.

Inito measures real values of E3G, LH, PdG, and FSH at once to give you a complete picture of your fertility levels and provides accurate results personalized to your unique body.

Regular ovulation predictor kits may not be helpful for people with conditions like PCOS or thyroid problems, as they rely on generalizations about hormone levels.

Inito, on the other hand, predicts your ovulation and fertile window based on personalized hormone maps. This feature provides more accurate predictions, making it easier for you to plan conception accordingly.

Confirmation of Healthy Pregnancy

Actual numerical values are necessary to know whether your PdG levels are sufficient enough to support a healthy pregnancy. For example, PdG levels lower than 7.9ng/ml in serum 6-8 days after ovulation have been linked to a reduction in pregnancy outcomes.

Most ovulation kits do not measure progesterone, which confirms ovulation and supports pregnancy. However, Inito measures all four hormones on a single test strip, including progesterone metabolite PdG, providing a complete picture of your cycles with results unique to your body.

Inito’s measurement of PdG during the 7-10 day window after ovulation can boost your chances of a successful and healthy pregnancy.

The Verdict

Our experience with Inito

We love that Inito provides real numerical values of fertility hormones, allowing you to capture your cycle’s unique patterns and pinpoint your ovulation more accurately.

With Inito, you can identify your entire 6-day fertile window, know if you’re experiencing healthy fertility, and know when to have sex to increase your chances of conceiving. It’s also much more affordable than other ovulation trackers on the market.

“=If you’re on the fence about buying this and are TTC, get it! It’s so worth it. I highly recommend!



I use it and think it’s an useful tool to check multiple hormone levels. I’ve also sent a couple of charts to my RE and he encourages me to keep using.



I have been using Inito for almost 6 months now and it has really been a god-send. I have PCOS and LPD (9 days!) and being able to track my hormones in real time has been SO HELPFUL when discussing my TTC issues with my doctor. It has saved me a lot of time doing bloodwork every few days like I had to do with my first daughter.



Is Inito Legit?

Inito is a legitimate way to check fertility windows

After using Inito for a few months, we found it to be a valuable fertility tracking tool that helps individual people get to know their unique cycles better (including those with conditions like PCOS).
