If you’re coming from Facebook and Instagram, here’s the fast answer: Mira’s Ultra4 Hormone Monitor Kit gives you actual hormone numbers for luteinizing hormone (LH), estrogen (E3G), pregnanediol glucuronide (PdG), and follicle-stimulating hormone (FSH). Clearblue’s Fertility Monitor shows fertility status bands classified as “Low,” “High,” or “Peak.” If you want precision you can act on, choose numbers.
TL;DR
- 4 hormones vs 2: Mira Ultra4 measures LH, E3G, PdG, FSH. Clearblue measures LH, E3G.
- Numbers vs bands: Mira gives quantitative values you can track, share, and act upon. Clearblue shows Low/High/Peak fertility status estimations without numeric evidence.
- Hormone health + trying to conceive (TTC) vs TTC only: Mira captures the hormone cycle as a whole, which reveals health insights outside of fertility status. By zeroing in on LH and E3G, the Clearblue Fertility Monitor solely evaluates the likelihood of conception.
- Regular cycles & beyond: Mira measures hormone levels for people with irregular cycles, PCOS, postpartum, and peri/menopause… not just those with average-length cycles, as Clearblue does.
- Demonstrated performance: Mira helped 91% of people find the root cause of their hormone-based symptoms, and on average, people conceive 10x faster with Mira than with the calendar method. Clearblue increases your chances of getting pregnant by 82%.
Introducing Mira & Clearblue
- Monitor + Ultra4 wands track four key hormones.
- Results are numeric and sync to the app with curves, notes, and exportable reports.
- Priced at $249 (including a 20-pack of Ultra4 Wands).
- Tracks two hormones and displays a fertility status (Low/High/Peak) on the device.
- Priced $207.98 at Walgreens (including a 30-pack of Test Sticks).
Given that Mira measures double the amount of hormones with higher accuracy than Clearblue, the roughly $50 difference in cost is negligible at best. If you need confirmation (PdG) and context (FSH), choose the kit that measures them.
