Overview of Inito

The Inito Fertility Monitor is a compact, app-connected device. It plugs into a smartphone and works with specially designed test strips. The monitor reads hormone levels directly from urine samples. It tracks estrogen (E3G), luteinizing hormone (LH), and progesterone (PdG). Inito uses AI to analyze hormone trends. The app shows a personalized fertility graph and tells users when they are most fertile. It also confirms ovulation based on the rise of PdG after the LH surge. This dual check helps ensure ovulation happened, not just that it might happen.
Pros and Cons of Inito
Pros
1. Tracks multiple hormones:
Inito tracks E3G, LH, and PdG, offering a full view of the fertility cycle. This gives more insight than tests that only track LH.
2. Confirms ovulation:
Most devices only predict ovulation. Inito confirms it by measuring a rise in PdG, which increases after ovulation.
3. Smartphone integration:
The device connects to a phone and works with the Inito app. The app gives clear, easy-to-read fertility charts.
4. Personalized data:
Inito adapts its predictions based on your unique hormone levels. It learns from each cycle.
5. Lab-grade accuracy:
According to the brand, Inito offers lab-quality hormone analysis. This makes results more reliable.
6. Discreet and compact:
The device is small and easy to use at home or on the go.
Cons
1. Higher cost upfront:
The initial price is higher than basic ovulation kits. You also need to buy test strips regularly.
2. Requires a compatible smartphone:
Not all phones support Inito. Users must check compatibility before purchasing.
3. Learning curve for some users:
While the app is user-friendly, some users may need time to get used to the data and charts.
4. Availability may be limited:
Inito may not be available in all regions or through local retailers.
Overview of Clearblue

Clearblue is a trusted brand in fertility and pregnancy products. Its fertility monitors are widely used and available in most stores. The most common options include:
- Clearblue Fertility Monitor Advanced
- Clearblue Digital Ovulation Tests
The Clearblue Fertility Monitor Advanced tracks estrogen and LH. It shows fertility levels as low, high, or peak on a digital screen. The Clearblue Digital Ovulation Test is a simpler product. It tracks LH only and shows a smiley face when a surge is detected, meaning ovulation is likely to occur soon. Both devices are easy to use and designed for at-home use.
Pros and Cons of Clearblue
Pros
1. Easy to use:
Clearblue tests are simple. The digital screen clearly shows results, so there’s no need to interpret lines.
2. Widely available:
Clearblue products are sold in pharmacies, grocery stores, and online. They’re easy to find.
3. Quick results:
You get results in minutes. No app or extra steps are needed.
4. Trusted brand:
Clearblue is a well-known and widely used brand with many years on the market.
5. Lower cost option available:
For budget-conscious users, Clearblue offers digital ovulation tests that cost less than full monitors.
Cons
1. Limited hormone tracking:
Clearblue monitors only track estrogen and LH. The digital ovulation test tracks LH only. It does not track progesterone, so it cannot confirm ovulation.
2. No app support (for most models):
Unlike Inito, most Clearblue products don’t sync with an app. You have to track fertility manually unless you buy the Connected version.
3. No personalized data analysis:
Clearblue products show basic results. They don’t adapt based on your unique hormone levels or cycle patterns.
4. Can be less helpful for irregular cycles:
Since Clearblue provides static readings, users with irregular cycles may find the data less reliable.
5. More test sticks required in long cycles:
If your cycle is long or unpredictable, you may need more test sticks, increasing the overall cost.
FAQs
What is the main difference between Inito and Clearblue fertility monitors?
The main difference lies in the number of hormones they track and the type of insights they provide. Inito monitors estrogen (E3G), luteinizing hormone (LH), and progesterone (PdG), allowing it to both predict and confirm ovulation. In contrast, Clearblue typically tracks only LH or LH and estrogen, offering ovulation prediction without confirmation. Inito uses app-based charts and digital insights, while Clearblue provides simpler, screen-based results without personalized cycle tracking.
Does Inito confirm ovulation?
Yes, Inito confirms ovulation by measuring PdG, a hormone that rises only after ovulation occurs. This gives users confidence that ovulation did happen, not just that it might. This confirmation feature is a key reason many choose Inito over other trackers. Learn more on the Inito FAQ page.
Can Clearblue confirm ovulation?
No, Clearblue does not confirm ovulation. It detects the LH surge, which signals that ovulation is likely to occur soon. However, it does not measure progesterone, so it cannot verify if ovulation actually happened. This is a limitation if you want full hormonal insight or have irregular cycles.
Is Inito suitable for women with irregular cycles?
Yes, Inito is especially useful for women with irregular cycles. Its app adjusts predictions based on your hormone trends, making it easier to track fertility even when cycles are unpredictable. The ability to monitor multiple hormones gives more accurate and personalized results. Read how Inito compares with similar options in our Inito vs Mira vs Kegg comparison.
Is Clearblue accurate for ovulation tracking?
Clearblue is accurate in predicting the LH surge, especially in women with regular cycles. It uses hormone detection, not just temperature, so it tends to be more reliable than calendar-based or basic strip tests. However, it may be less effective for those with hormone imbalances or irregular cycles.
What hormones does Inito track?
Inito tracks three key fertility hormones: Estrogen (E3G) – rises before ovulation, Luteinizing Hormone (LH) – spikes before ovulation, and Progesterone (PdG) – rises after ovulation. This hormone combination provides a complete view of the fertile window and confirms ovulation. Learn more from the Inito blog.
Do I need an app to use Clearblue?
No, most Clearblue devices do not require an app. They show results directly on a digital screen. However, the Clearblue Connected Ovulation Test System is one exception—it works with a smartphone app. Still, most users rely on the standalone version for simplicity.
Is Inito easy to use for beginners?
Yes, Inito is designed to be user-friendly. After plugging the device into your smartphone, the app guides you step-by-step through the testing process. The app also interprets hormone levels and displays your fertility window visually. Beginners can understand their cycle easily using Inito’s digital charts.
How long does it take to get results with Inito?
Inito gives results within a few minutes of testing. After dipping the strip in urine, you insert it into the device, and the app displays your hormone levels. The process is fast and provides lab-grade data without needing to leave your home.
How long does Clearblue take to give results?
Clearblue’s digital ovulation tests show results in about 5 minutes. You simply insert the test stick into the holder, dip it into urine or place it midstream, and wait for a digital result—usually a smiley face for a positive LH surge.
Which is more affordable: Inito or Clearblue?
Clearblue generally has a lower upfront cost, especially the digital ovulation tests. Inito, while more expensive initially, provides more detailed tracking and may reduce the need for additional testing tools. If you’re looking for budget-friendly options, Clearblue is a good starting point. However, if you need deep insights or have fertility concerns, Inito may offer more value long-term.
Can I use Inito if I already track temperature?
Yes, and combining both can enhance your understanding of your cycle. While Inito focuses on hormones, temperature-based wearables track basal body temperature (BBT) trends. Some users pair Inito with devices like Tempdrop or Femometer Ring. To see how these compare, check our guides on Femometer Ring vs Tempdrop and Tempdrop vs Ava.
Does Clearblue work with irregular cycles?
Clearblue can work with irregular cycles, but it may be less accurate in predicting ovulation. This is because the hormone surge might occur outside of the expected testing window. In such cases, more test sticks may be required, increasing costs. For irregular cycles, a tool like Inito or apps that adapt to your unique data may offer better accuracy.
Can Inito help with early pregnancy detection?
Inito focuses on ovulation and hormone tracking, not pregnancy detection. However, knowing when ovulation occurs can help you time pregnancy tests more accurately. For early pregnancy signs, visit Clearblue’s guide on early symptoms of pregnancy.
Are there alternatives to Inito and Clearblue?
Yes, there are several fertility tracking tools on the market, including Femometer, Mira, Natural Cycles, and Tempdrop. Each offers different methods—from hormone testing to temperature tracking. You can explore more about how they compare in these detailed reviews: Femometer Ring Reviews and Femometer vs Natural Cycles.
