Proov vs. Mira vs. Inito: The At-Home Hormone Test Comparison, Decoded

You're not choosing between three versions of the same thing. You're choosing between a gadget and a paper strip plus your phone. Here's the honest breakdown — what they measure, what they cost, and which one actually fits how you want to live.

Proov vs. Mira vs. Inito: The At-Home Hormone Test Comparison, Decoded

If you've been Googling 'Proov vs. Mira vs. Inito' at 11pm, this is for you. Three at-home hormone tests, three very different philosophies. Here's the honest breakdown — what they measure, what they cost, and which one actually fits how you want to live.

You're not choosing between three versions of the same thing. You're choosing between a gadget and a paper strip plus your phone. That single difference shapes everything else — the upfront cost, the daily ritual, the e-waste in your bathroom drawer, and how much homework you're signing up for.

"Most people aren't actually shopping for more data. They're shopping for answers, less hassle, and the confidence they're reading their own body right."

Let's get into it.

The honest breakdown — what they measure, what they cost, and which one actually fits how you want to live.

Credit where it's due. Mira and Inito are real instruments built by serious teams, and all three of these tests do something the drugstore aisle can't: they go beyond the 'is it a smiley face or not' guessing game.

Every one of them measures PdG — the urine metabolite of progesterone that confirms ovulation actually happened, instead of just predicting that it might. That matters, because a positive LH strip tells you your body tried to ovulate. It doesn't tell you it succeeded. PdG is the receipt.

All three also track multiple hormones across the cycle rather than a single data point. So if you're comparing any of these three to a basic LH-only ovulation kit, you're already trading up. The real question isn't whether they work. It's which approach fits you.

The three differences that actually decide it.

1. A device you buy and charge — or just the phone in your hand. Mira and Inito are both hardware companies. You buy a reader, you keep it charged or connected, you pair it, and you feed it strips or wands. The hardware is genuinely clever — but it's also a thing you have to purchase, maintain, store, and eventually replace.

Proov skipped the gadget. The reader is the camera already in your pocket. You dip a paper strip, snap it in the Proov Insight app, and the app does the reading. Nothing to charge. Nothing to pair. Nothing to break the week before your fertile window. And when you're done, it's a paper strip — not another piece of electronics headed for a landfill. If the idea of one more device to manage makes you tired, that's the whole ballgame right there.

2. 'Here are your numbers' vs. 'Here's what to do.' This is the philosophical fork. Mira and Inito are built for the data maximalist — the person who wants exact numeric hormone values charted every single day and enjoys interpreting the trend lines herself. If that's you, you'll love them. Genuinely.

Proov is built for the person who wants the answer, not the spreadsheet. The Insight app turns your results into a guided, personalized protocol — which test to take on which day — and rolls your progesterone data into a single patented Score that tells you whether your ovulation was strong, not just what your PdG was on cycle day 22. It's hormone intelligence, not a science project. Same biology underneath. Very different experience of using it.

3. The credential that's hard to copy. Proov is the first and only FDA-cleared at-home test to confirm successful ovulation. FDA clearance isn't the same as a company being 'FDA-registered' — clearance means the FDA reviewed the test's accuracy for its specific intended use and signed off. For something this important, that distinction is worth understanding before you spend a dollar.

And because Proov tests across the full cycle — including the implantation window, when your body is preparing to support a pregnancy — you're not just timing sex. You're checking whether the back half of your cycle is doing its job.

So which should you actually pick? Here's the honest call. Choose Mira or Inito if you want daily numeric hormone values, you love a detailed chart, and a dedicated device doesn't bother you.

Choose Proov Complete if you'd rather not buy or babysit another gadget, you want an FDA-cleared way to confirm ovulation (not just predict it), and you want the app to hand you a protocol and a clear Score instead of a wall of numbers to decode yourself. All for $99.99, read by the phone you already own, on paper strips you can toss in the trash.

Most people aren't actually shopping for 'more data.' They're shopping for answers, less hassle, and the confidence they're reading their own body right. That's the lane Proov was built for.

Quick answers.

Do all three confirm ovulation? All three measure PdG, the progesterone metabolite that confirms ovulation actually occurred. Proov is the only one of the three that holds FDA clearance specifically for at-home ovulation confirmation.

Which is cheapest to start? Proov Complete starts at $99.99 with no separate device to buy, since it's read by your smartphone. Mira and Inito require purchasing a reader on top of strips or wands.

Do I need to buy a device? With Proov, no — the Proov Insight app uses your phone's camera. Mira and Inito both require their own electronic reader.

What hormones does each one track? All three track four cycle hormones. Proov measures FSH, LH, E1G (estrogen), and PdG (progesterone). Mira and Inito both measure LH, estrogen, PdG, and FSH.

Is Proov good for irregular cycles or perimenopause? Proov's full-cycle approach and app-guided protocol are designed to adapt to your individual hormone pattern, which is exactly what irregular cycles and perimenopause call for. (For peri specifically, look at Proov Empower.)

Proov is made by women's health scientists led by founder Dr. Amy Beckley, PhD — the inventor of the first FDA-cleared at-home test to confirm ovulation. Proov supports your understanding of your hormones; it doesn't diagnose, treat, or cure any condition. Talk to your healthcare provider about your results.
