Curious about how to use the Inito Fertility Monitor? You’re in the right place. Whether you’ve just unboxed your device or want to make sure you’re testing the right way, this guide covers everything—from when to test to what your results mean. Let’s walk through it step by step.
Key Takeaways
- Inito measures four key fertility hormones – estrogen, LH, PdG (urine metabolite of progesterone), and FSH to give you a complete picture of your cycle.
- You should start testing from cycle day (CD) 6, and the Inito app will guide you on which days to test.
- Always use first-morning urine for best results, as hormone levels are most concentrated.
- To take a test, collect your urine, dip the strip for 15 seconds, cap it, attach the monitor to your phone, and scan using the free Inito app.
- Your results will show one of these five fertility ratings: High Fertility, Peak Fertility, Low Fertility, Ovulation Confirmed, or Waiting for PdG Rise.
- High and Peak Fertility together mark your fertile window. Ovulation Confirmed means the egg was released after your Peak Fertility.
- For the most accurate results, don’t skip test days, keep your phone still while the test is running, and always follow app instructions.
What is the Inito Fertility Monitor?
The Inito Fertility Monitor is a lab-grade fertility monitor that measures four key fertility hormones in your urine. Inito connects to your smartphone and essentially transforms it into a mini hormone lab, giving you personalized, real-time insights into your fertility.
What Hormones Does Inito Measure?
Let’s break down the four hormones that Inito measures and what they indicate:
- Estrogen: Starts rising 3-4 days before ovulation. A key sign your body is entering the fertile window (aka the time in your menstrual cycle when you’re most likely to conceive).
- Luteinizing Hormone (LH): Rises 24-36 hours before ovulation. Think of it as the trigger that releases the egg.
- PdG (urine metabolite of progesterone): Rises after ovulation. A steady and consistent rise in PdG over a few days indicates that ovulation has actually happened.
- Follicle Stimulating Hormone (FSH): Involved in kick-starting your cycle and tracking your follicle growth.
So by measuring these four hormones in your urine, Inito gives you a complete picture of what’s happening in your body – it tells you your full fertile window, and also confirms ovulation, all on a single test strip.
Why Should You Choose Inito?
There are a lot of ovulation trackers and fertility monitors out there. So why go with Inito?
Here’s the breakdown:
- Lab-grade accuracy: Studies show that Inito is 96% as accurate as a blood test and confirms ovulation with more than 99% specificity.
- Ovulation confirmation: Unlike ovulation tests that measure only LH to predict ovulation, Inito measures PdG (the urine metabolite of progesterone) to tell you if you’ve actually ovulated.
- Actual numerical data: Most tests out there are ambiguous and give you a yes/no result. Inito measures real numerical values of your hormones, giving you powerful insights into your cycles.
- Personalized tracking: You get your results based on your unique hormone patterns.
- At-home testing: Super easy to use at home, connects to your iPhone, no wires, no painful jabs or trips to the doctor.
When Should You Test With Inito?
Ideally, you need to start testing from cycle day (CD) 6 onwards.
The first day of your period is considered cycle day 1. So you need to start testing five days later, and continue testing based on what the app tells you.

Step-by-Step Guide to Testing With Inito
Let’s walk through what testing looks like.
To get started, you’ll need:
- The Inito Fertility Monitor
- Your phone
- Your phone attachment clip
- Inito Test Strips
- Urine cup
Step 1: Download and register with the Inito App
You can download the Inito app (for free) from the App Store. The app will walk you through the sign-up process.
If you’ve bought the Inito monitor already, swipe through the introduction and select the “I Have Fertility Monitor” option on the last page.
Scan the QR code printed inside the Inito box, or enter the code manually. Click on “Add Fertility Monitor”.
You’re now onboard! You can feed in your previous cycle dates on the app.
Step 2: Set up your Inito Fertility Monitor
Remove the pull-out tab to turn your monitor on. Do not reinsert the tab.
Now, attach the phone clip to the monitor – you can do this by aligning the monitor with the clip and gently sliding it into the clip until you hear a click sound.
(Pro-tip: The hole in the mounting clip should be aligned with the glass window on the device.)
You’re all set to start testing now!
Step 3: Taking a test
To know when to start testing, you can check the calendar on the app. You can see all your test-required days highlighted in the calendar with the 
icon.
Click on “Take a Test” in the app.
(Pro-tip: Make sure you’re using your First-morning urine (FMU). FMU offers a long, uninterrupted gap for urine collection. This helps balance out fluctuations that could happen due to food or fluid intake, activity, and other factors.)
- Collect your sample
Grab the urine collection cup and fill it just to the marked line – no more, no less.
- Dip the strip
Gently dip the paper end of the Test Strip into the cup and hold it there for exactly 15 seconds. No need to count in your head; use the handy timer in the Inito app to make it easy.
- Remove the strip
Take the strip out of the cup. Now, grab the cap on the other end of the strip (the plastic end) and place it over the paper end (the part that was dipped). Important: don’t insert the strip into the monitor just yet!
- Remove your phone case and screen guard
Make sure your phone is case-free and that there’s no screen guard getting in the way.
- Attach the monitor
Slide the monitor onto your phone using the mounting clip until it fits snugly. You might need to apply a bit of pressure – that’s totally normal.
(Important safety note: Never insert the wet, dipped end of the strip into the monitor. This can damage your device and void your warranty. Always insert the plastic end into the monitor.)
- Scan and get your results
Once your strip is in place, the Inito Fertility Monitor will automatically measure your urine hormone levels. In just a few seconds, the app will show your fertility status along with helpful suggestions to guide your journey.
- Clean up
When you’re done, remove the Test Strip and toss it in the trash, not the toilet. Then detach the monitor from your phone and store it safely in your Inito box until next time.
Step 4: Read Your Results
You’ll see your numerical hormone values and clear insights. The app tells you where you are in your cycle and what your chances of conceiving are on that day.
What Do My Test Results Mean?
This is where Inito shines. Instead of vague “positive” or “negative” results, it gives you actual numbers and context by looking for a rise from your baseline hormone values.
What You Might See:
High Fertility (Green on your chart)
You’re in your fertile window!
What it means: Your estrogen levels are rising, which usually means your body is getting ready to ovulate soon.
What to do: This is a great time to start having sex every day or every other day. Sperm can stay in your reproductive tract for up to 5 days, so timing things now boosts your chances.
Peak Fertility (Purple on your chart)
This is your most fertile day!
What it means: Your LH (luteinizing hormone) is surging – ovulation is likely to happen in the next 24 to 36 hours.
What to do: If you’re trying to conceive, now is the best time to have sex. This is when your chances are highest.
Low Fertility
This is the most common reading outside your fertile window.
What it means:
- Before ovulation: Your estrogen and LH levels are still low. No egg has been released yet.
(Note: Sometimes your estrogen levels may rise without a subsequent rise in LH. In this case, you might see several days of High Fertility (up to 8 days), and then, if no LH rise occurs, a return to Low Fertility. Don’t worry, this is normal and can occasionally happen. If your LH rises later in the cycle, you’ll see a Peak Fertility result at that time.)
- After ovulation: If ovulation has already happened, your fertile window has passed, meaning your chances of pregnancy are low. PdG may be on the rise now if ovulation occurred.
What to do: Just keep tracking! Low fertility isn’t a bad thing – it just means you’re not in your fertile window right now.
- Ovulation Confirmed (Blue on your chart)
Ovulation has officially happened.
What it means: Your PdG (urine metabolite of progesterone) has shown a steady and consistent rise – this confirms your body released an egg after your latest LH surge.
What to do: Further testing is optional now. So you can relax knowing ovulation took place.
- Waiting for PdG Rise
Ovulation hasn’t been confirmed yet.
What it means: Your PdG levels haven’t shown a steady and consistent rise from your baseline yet. This is totally normal – it can take up to 9 days for your PdG to rise consistently and show up in urine.
Note: While your result on the Home Screen reads Waiting for PdG Rise, your Inito chart will show Low Fertility since chances of conceiving are low during this time.
What to do: Keep testing daily for now, and try not to stress. Everyone’s body is a little different.
Best Practices for Testing
To get the most reliable results, keep these tips in mind:
- Always test with first-morning urine
That’s when your hormones are most concentrated. Not using FMU can cause your results to be less accurate.
- Fill up to the given mark
Make sure to dip the strip into the Inito urine cup and fill it up to the given line. Do not dip the strip in a cup other than Inito’s urine cup.
- Leave your phone
Keep your phone on a flat surface while the test runs. More importantly, do not use your phone while the test is running.
- Don’t skip days
Hormone shifts can happen fast! Testing (according to app instructions) is the best way to capture the complete picture.
