Know your moment
The first wearable that continuously monitors your fertility hormones and alerts you at the exact moment that matters most.
No more sticks. No more guessing. Just a simple patch, a smart prediction engine, and a notification when you need it.
Next fertile window
~24 hours
Fertility tracking is broken
Busy professionals do not have time to test daily, track symptoms, or have sex every other day “just in case.” Current solutions are either accurate but manual, or convenient but guesswork.
12-24 hour window
The LH surge that triggers ovulation lasts just 12-24 hours. Miss it and you wait another month.

LH surge duration
Run out of sticks
Testing daily with urine strips means buying, remembering, and timing. Life gets in the way.

Inaccurate timing
Temperature and symptom tracking are indirect proxies. They tell you after ovulation, not before.

Stress compounds
Each missed cycle adds anxiety. Couples feel like they are failing at something that should be natural.

Where the market is today
Products like Clearblue, Mira, and Inito measure real hormones but require daily urine testing. High compliance burden, easy to miss the window.
Wearables like Ava and Oura track temperature, heart rate, and sleep. They infer fertility from proxies, not actual hormones. Nice UX, weak signal.
Nobody combines continuous, direct hormone measurement with real-time alerts. Until now.
From patch to perfect timing
Four steps. Zero effort. One notification that changes everything.
Apply the patch
A tiny, painless microneedle patch worn on your upper arm. Samples interstitial fluid continuously, like a CGM but for fertility hormones.
Replace every 7-14 days. Discreet, comfortable, and waterproof.
AI predicts your surge
Our prediction engine combines your real-time hormone signal with your personal cycle history to predict your LH surge before it peaks.
Gets smarter every cycle. Population-level models personalised to you.
Get alerted at the right moment
A simple push notification tells you and your partner exactly when your fertile window opens. No interpretation needed.
"LH surge detected. Your next 24-36 hours are optimal." That is it.
Track and learn
After each cycle, Ovio confirms ovulation via progesterone trends and builds a richer picture of your hormonal health.
Cycle insights, luteal quality scores, and anomaly detection for PCOS.
Four hormones. One window.
Your menstrual cycle is driven by four key hormones. Ovio tracks them continuously to pinpoint the exact moment of ovulation.
