When choosing a fertility tracker, many users compare Inito and Proov. Both monitor hormone levels to support ovulation tracking, but they offer different features and suit different needs.
Key Takeaway:
- Inito tracks three hormones (E3G, LH, PdG), giving a full view of your fertility window.
- Proov focuses on PdG to confirm ovulation, mainly during the luteal phase.
- Inito offers both prediction and confirmation of ovulation in one system.
- Proov is ideal for post-ovulation tracking and checking progesterone sufficiency.
- Inito uses a digital reader and smartphone app for precise, quantitative results.
- Proov uses test strips with optional app support, offering simpler, affordable testing.
- Choose Inito for irregular cycles, hormone insight, or advanced fertility planning.
- Choose Proov if you only need to confirm ovulation or work with a fertility specialist.

What is Inito?
Inito is a smartphone-connected fertility monitor that tracks three key hormones from urine samples: Estrogen (E3G) – rises before ovulation, Luteinizing Hormone (LH) – spikes just before ovulation, and Progesterone (PdG) – confirms ovulation after it occurs. Inito provides quantitative results through its app. Users dip a test strip in urine, insert it into the Inito device, and view hormone levels and ovulation charts directly on their phones.
What is Proov?
Proov is a hormone test brand focused on progesterone tracking. Its most popular product, Proov Confirm, measures PdG levels in urine after ovulation. Proov also offers LH tests and a cycle tracking app, but its core focus is confirming ovulation rather than predicting it. Proov tests are qualitative. Users interpret results using colored lines, similar to pregnancy tests, although Proov also offers digital analysis via the app with its Proov Insight system.
Inito: Pros and Cons
Pros
- Tracks three hormones (E3G, LH, PdG) for full cycle insight
- Confirms and predicts ovulation in one system
- App provides charts, cycle patterns, and hormone trends
- Reusable device reduces waste long term
- Ideal for irregular cycles or detailed fertility planning
Cons
- Requires smartphone compatibility and app setup
- Higher initial cost
- Limited to users comfortable with digital tools
Proov: Pros and Cons
Pros
- Focus on progesterone (PdG) makes it ideal for confirming ovulation
- Simple to use for mid-luteal phase testing
- No device required—only test strips and the app
- More affordable upfront
- Works well for tracking ovulation after the fact
Cons
- Does not track estrogen or LH (except in separate tests)
- No ovulation prediction, only confirmation
- Results can be subjective without app interpretation
- Less data for in-depth cycle analysis
Key Differences: Inito vs Proov
Inito tracks E3G, LH, and PdG, offering both ovulation prediction and confirmation through its digital device and app. Proov focuses mainly on confirming ovulation by detecting PdG, using test strips and a simpler app. Inito is best for users who want a full hormonal view and advanced tracking, while Proov is best for those focused specifically on confirming ovulation in the luteal phase.
| Feature | Inito | Proov |
|---|---|---|
| Hormones Tracked | E3G, LH, PdG | PdG (with optional LH) |
| Ovulation Prediction | Yes | No |
| Ovulation Confirmation | Yes (quantitative) | Yes (qualitative or app-based) |
| App Integration | Required, detailed tracking | Optional, simpler interface |
| Best For | Full cycle insight, irregular cycles | Confirming ovulation only |
| Testing Method | Digital reader + strips | Test strips only |
Which Should You Choose?
Choose Inito if you want a complete hormone overview, especially if you’re trying to conceive, have irregular cycles, or want both prediction and confirmation of ovulation. Choose Proov if you mainly want to confirm ovulation, especially in the luteal phase, or if you’re working with a doctor or fertility coach to assess progesterone levels.

FAQs
What is the key difference between Inito and Proov?
The main difference is in their hormone tracking. Inito tracks three hormones—estrogen (E3G), luteinizing hormone (LH), and progesterone (PdG)—allowing it to predict and confirm ovulation. Proov focuses primarily on confirming ovulation by testing PdG after ovulation. This makes Inito suitable for full-cycle tracking, while Proov is better for confirming luteal phase health.
Does Inito confirm ovulation?
Yes. Inito measures PdG (pregnanediol-3-glucuronide), a urine metabolite of progesterone. A rise in PdG confirms that ovulation has occurred. Inito provides quantitative levels through its app, giving users clear confirmation along with timing.
Does Proov confirm ovulation?
Yes. Proov tests confirm ovulation by checking PdG levels during the luteal phase—typically 7–10 days after the LH surge. A sustained PdG level over multiple days suggests successful ovulation and supports potential implantation.
Can Inito predict ovulation?
Yes. Inito tracks estrogen (E3G) and luteinizing hormone (LH) to identify the fertile window and predict ovulation. E3G rises before ovulation, while LH surges just before it. This allows Inito to notify users of high fertility days in advance.
Can Proov predict ovulation?
No. Proov does not predict ovulation. It focuses on testing PdG after ovulation to confirm whether it occurred. If you want to know your fertile days in advance, Inito or other hormone trackers may be more suitable.
Is Inito better for irregular cycles?
Yes. Inito adapts to individual hormone patterns, which is helpful for users with irregular cycles. It tracks daily hormone trends, making it easier to identify fertile days and ovulation even when cycle lengths vary. For more, see Inito vs Mira vs Kegg.
Can Proov be used with irregular cycles?
Yes, but with limitations. Since Proov is used after ovulation, you need to detect your LH surge first. If your cycles are irregular, predicting the right day for PdG testing can be harder. Some users pair Proov with LH tests or apps for better timing.
How do Inito and Proov measure hormones?
Inito uses a smartphone-connected reader to scan test strips and send hormone levels to its app. It provides numeric values for E3G, LH, and PdG. Proov uses color-line test strips, similar to pregnancy tests, and results are interpreted visually or via the Proov Insight app.
Do I need a phone to use Inito?
Yes. Inito requires a smartphone and app for full functionality. The reader connects directly to the phone, and the app displays your hormone charts and fertility predictions. The Inito app is available for iOS and Android.
Do I need a phone to use Proov?
Not necessarily. Proov test strips can be read visually without an app. However, for digital tracking and cycle analysis, using the Proov Insight app improves accuracy and usability.
Which is more affordable: Inito or Proov?
Proov has a lower upfront cost, since it uses simple strips without a device. Inito has a higher initial price for the device but offers more comprehensive hormone tracking and may reduce the need for multiple tests or devices over time.
Can I use Inito and Proov together?
Yes. Some users use Inito for full-cycle tracking and Proov as a secondary check on PdG levels in the luteal phase. This combination can offer reassurance, especially if working with a fertility specialist or trying to understand luteal phase sufficiency.
Does Proov offer LH testing too?
Yes. Proov sells LH test strips separately. These can help you identify your LH surge before using PdG tests. However, these LH tests are separate from the main Proov PdG kits and do not integrate directly with ovulation prediction tools like Inito.
What are the hormone insights offered by Inito?
Inito offers real-time hormone levels for estrogen, LH, and PdG. This allows you to understand when your fertile window begins, when ovulation is likely, and whether it occurred. The app also shows cycle charts to spot trends over time. Explore more on the Inito blog.
What does Proov Insight offer?
Proov Insight is the companion app for Proov tests. It lets users log test results, view suggested testing windows, and track PdG levels across the luteal phase. While not as detailed as Inito’s hormone charts, it simplifies ovulation confirmation and progesterone tracking.
Conclusion
Choosing between Inito and Proov depends on your fertility goals. If you want a complete picture of your cycle—with hormone trends, ovulation prediction, and confirmation—Inito is the better choice. It’s ideal for detailed tracking and irregular cycles. If your focus is simply on confirming ovulation and monitoring progesterone levels, Proov offers a simple, affordable solution. Both tools serve different needs, and understanding your priorities will help you pick the one that fits best.
