The Halo Smart Ring

Your body talks while you sleep. Halo listens.

The Halo Ring tracks your basal body temperature continuously overnight — thousands of readings at clinical-grade accuracy — from the most precise sensor position on your body: your finger. No 6 AM alarms. No thermometer fumbling. No "did I move before I took my temperature." Wear it and forget it.

But Halo isn't another wearable that gives you data and leaves you alone with it. Every data point flows directly to Kai and your Conceivable care team. Temperature shift confirms ovulation? Kai updates your plan. Blood sugar spiking after dinner? Olive adjusts your nutrition that week. HRV dipping? Seren checks in on your stress.

Other wearables tell you what happened. Halo + Kai tell you what to do about it.

Tracks what matters for fertility:
— Continuous basal body temperature (ovulation, progesterone, implantation potential)
— Blood sugar patterns (hormone disruption, egg quality, inflammation)
— Sleep quality, HRV, and stress indicators

Specs:
— 7+ day battery
— ±0.1° accuracy
— Water resistant
— No ring subscription (pairs with Conceivable app, $14.99/mo)

Every night you wear it, your Conceivable Score gets smarter and your plan gets more precise.
