- Both Mira (Max Wands) and Oova measure LH, E3G and PdG in urine and report numeric levels in an app 12.
- Mira uses a reusable reader; Oova reads strips with your phone camera and needs no extra device 32.
- Listed prices: Mira Max Kit $219 to $229 plus $89 per 20 refill wands; Oova $159 per one-cycle kit or $129 per month 315.
- Mira offers an FSH option (Ultra4); Oova does not list FSH 42.
- Both call themselves FDA-registered, which FDA says does not mean approved or cleared 3210.
Mira and Oova both measure the same three fertility hormones in urine (LH, E3G and PdG) and show numeric results in an app.12 The main differences are how the test is read (Mira uses a reusable reader, Oova uses your phone camera), how you pay (Mira has a device cost plus refills, Oova sells per-cycle kits), and whether you want FSH, which only Mira offers.342
This comparison is researched, not hands-on: we have not used either product. Every fact comes from the companies' official pages and FDA, checked October 2, 2026.

How each one reads your hormones
Both are built on the same hormone biology. LH surges about 1 to 1.5 days before ovulation, E3G builds up around ovulation, and PdG rises afterward.67
Mira uses a small reader. You dip a wand, insert it into the monitor, and results appear in the Mira app.3 Mira says the monitor works with all its wand types, including LH and E3G only, PdG only, FSH only, and the four-hormone Ultra4 wands.34
Oova has no reader. You dip a strip and scan it with your phone camera, and the app reports quantitative LH, E3G and PdG levels.2 Oova says its results are interpreted against your own hormone baseline.8
Cost over several cycles
Many people track for more than one cycle, so the first purchase is only part of the cost. Using listed prices, and assuming 20 Mira wands per cycle (the top of Mira's suggested range), here is a rough three-cycle estimate. This is our own arithmetic, not a figure from either company.
| Scenario (3 cycles) | Mira Max | Oova |
|---|---|---|
| First cycle | $229 (kit with 20 wands) 3 | $159 (one-time kit) 5 |
| Two more cycles | $178 (two 20-wand refills at $89) 1 | $258 (two months at $129) or $318 (two more kits at $159) 5 |
| Approximate total | About $407 | About $417 to $477 |
If your cycles are long or irregular, either system may need more tests than average, which raises the cost.9
Choose Mira if
- You want one wand that reads all three hormones at once.1
- You want the option to add FSH tracking later with Ultra4 wands.4
- You expect to track for several cycles and want lower refill costs per test.1
- You live outside the U.S. and Canada, where Mira lists shipping.3
Choose Oova if
- You prefer no extra device and want to use your phone.2
- You want a lower first purchase for a single cycle.5
- Your clinic uses Oova's real-time clinician dashboard.2
- You may be eligible for Carrot Fertility reimbursement through an employer.5
Claims to read carefully on both sites
Both companies say they are FDA-registered. FDA states that a registration and listing entry "does not denote approval, clearance, or authorization" of a device.10 Neither claims to be a diagnostic or contraceptive device, and FDA advises against using home ovulation tests to prevent pregnancy.326
Accuracy and success claims on both sites are company-reported. Mira's footnotes describe internal lab comparisons, retrospective user data and a small pilot that was not peer-reviewed; Oova's correlation figure differs between its pages (93% and up to 99%).325 We found no independent study comparing the two directly.
What matters more than which monitor you pick
Neither monitor replaces folic acid or a clinician. CDC recommends 400 mcg of folic acid daily for anyone who could become pregnant, and USPSTF recommends starting at least one month before conception, because the neural tube closes about 26 to 28 days after fertilization.111213 See folic acid before pregnancy and how much folic acid for pregnancy.
If you have been trying for 12 months, or 6 months if you are over 35, ACOG recommends an infertility evaluation for both partners.14 For other options, including low-cost LH strips, see how to choose the best ovulation test, or read the full Mira review and Oova review.
