Not all ovulation tests are created equal
Most ovulation tests predict your fertile days by tracking Luteinizing Hormone (LH), but fail to measure the hormone that actually confirms your ovulation: PdG (urine metabolite of progesterone).
What makes Inito different?
Measures LH, Estrogen, PdG, and FSH, not just LH
Confirms ovulation by measuring PdG
Identifies your right six days to try
Delivers personalized insights from your actual hormone values, not population averages

Hormone data points tracked
Confirm ovulation with real data
Inito measures PdG, the urine metabolite of progesterone, which rises only after ovulation. That means you don't rely on prediction alone. You see whether ovulation actually happened – or didn't – in your cycle.

Why measure PdG?
PdG - urine metabolite of progesterone
1 in 3
women have anovulatory cycles*
If ovulation occurs, the levels of Progesterone and its urine metabolite PdG rise after a few days and stay elevated. Sustained, elevated PdG levels after peak fertility indicate a successful ovulation.

See your six right days to try
OPKs often miss your fertile window due to confusing faint lines and constant false positives because they rely on average thresholds. Inito tracks your six right days by adapting to your unique hormone levels and measuring all 4 hormones
Estrogen, rises 3-4 days before ovulation
LH, surges 24-36 hours before ovulation
FSH, tracks follicle growth
PdG, which rises after ovulation

“I recommend Inito because it gives patients objective, cycle-specific insight without requiring frequent clinic visits. I’ve seen patients realize they weren’t ovulating consistently, which helped them seek support sooner.”

The most precise hormone readings
at home1
Powered by Inito Spectral Mapping™ Technology, Inito delivers the most precise fertility hormone readings, outperforming other at-home tests in head-to-head lab testing.
4 hormones.
Measured separately
Most monitors test multiple hormones on one track, where one hormone can interfere with another and make results less accurate. Inito measures hormones in four independent tracks, so every reading stays precise.
Every hormone shift, precisely measured.
The only at-home monitor that double-checks every test with two sensing methods: fluorescence and visual colorimetric imaging. Designed to detect subtle hormone shifts that other tests can miss.
Captures 100x
richer data
Inito captures a full 2D image of your entire test surface over time, collecting over 100× richer data from every test. That richer data helps our AI correct for real world variables — delivering lab-grade reliability at home.
1: “Most precise” refers to system-level precision measured in controlled laboratory testing, based on lower between-device variability across key hormones, concentrations, operators, days, and strip lots. Compares Inito to other U.S. over-the-counter at-home fertility monitors that provide numeric or graded hormone values and measure the same hormones as Inito.

After Miscarriage
"I had my ovulation date completely wrong using just LH strips. I continued tracking (with Inito) after my (miscarriage) to monitor my hormones until they get back to normal. I decided to try again I got my second BFP."
Ashmanie PersaudEdgewood, Maryland
PCOS
"After seeing that I was not ovulating, I just continued experimenting with vitamins. I saw that I actually ovulated on my own out of nowhere! Without Inito, I would have never known."
Cierra DWest Des Moines, Iowa
Irregular Cycles
"Inito helped me uncover that I was having several anovulatory cycles. The app was easy to use; it's an advanced, reliable tool, and I believe it can help so many others navigating a difficult TTC journey."
Amanda BurghauserForest Hill, Louisiana
Trying after 35+
"The first cycle on Inito, I noticed my luteal phase was only 9 days. The Inito Facebook support group helped me realize I should check with my doctor about luteal phase defect."
Danielle BabbittBedford, Texas
PCOS
"I was stuck in long, anovulatory cycles. That's when Inito changed everything. If it weren't for Inito, I would have missed my chance completely and ended up on medicated cycles."
Bailey DeCamillisArvada, Colorado
Pre IVF
"Doctors kept trying to push us to IVF. Six months into using Inito, we were able to conceive our baby boy naturally. I was drawn to its numerical data and tracking of multiple variables."
Jessica HolmesDawsonville, Georgia
Trying after 35+
"As an older woman with extremely low AMH, time was of the essence to conceive quickly, and using Inito made that happen for us. We were better prepared through Inito to track my fertile window."
Leah Alissa BayerBellingham, Washington
After Miscarriage
"My last miscarriage was Oct, I knew something needed to change. If it wasn't for Inito I would have never been able to track what was going on. Even though my numbers were low Inito still knew I ovulated."
Joanne WrenMount Washington, Kentucky
Irregular Cycles
"Irregular periods made tracking my cycle feel impossible. Inito gave me real-time insights into my hormones. It was empowering to finally understand my body and recognize my true fertile window."
Pamela PepeSan Diego, California
PCOS
"Because of my Inito results, I called the (IUI) fertility clinic and they had me trigger immediately. Without Inito my timing would have been off and we wouldn't have our baby."
Kelly WorkmanSalem, Missouri
After Miscarriage
"We had one miscarriage. I wanted more data and more information, and Inito gave me just that! I loved using it to confirm ovulation. It felt good to confirm in the comfort of my home."
Abigayle (Abi) TeetersMaple Grove, Minnesota
Pre IVF
"Before taking that (IVF) leap, I decided to try Inito. Within 3 months of using Inito, I noticed my hormones might need additional support. My healthcare provider suggested progesterone creams to optimize my levels."
Janette SaldanaLindsay, California
Trying after 35+
"I felt like time wasn't on my side, I was approaching 40. Tracking with Inito took the guess work out to see my hormone levels. I was able to conceive with the help of both Inito and my doctor."
Sarah GondekHancock, Michigan
Irregular Cycles
"With Inito, I could see exactly where I was in my cycle - whether I was gearing up to ovulate, or whether I'd missed it altogether. It was as though I had a map to guide me through the fog of uncertainty."
Rachel Lautigar BaudoinSan Marcos, Texas
Pre IVF
"I was preparing to move forward with IVF. But Inito continued to show strong ovulation patterns, which gave me hope. I ended up getting pregnant just one week before starting IVF!"
