Beakn Halo
Titanium. Screenless. 10‑day battery.
A smart ring carved from a single piece of titanium. Multi‑channel PPG, skin temperature, HRV, and SpO₂ — 24/7, no subscription, no screen, no compromises.
A wearable that
disappears.
Most wearables ask you to look at them. Beakn Halo asks for nothing. There's no screen, no haptic, no app icon glowing for your attention — just a single piece of milled titanium that reads your body 24 hours a day and quietly hands the answers to the AI.
Three multi‑channel PPG sensors and an infrared thermopile sit flush against the inside of the band. They capture cardiac waveforms, blood‑oxygen, skin temperature, and HRV at a sampling density that rivals chest‑strap straps and clinical pulse oximeters — all from a 4 mm contact patch on the underside of your finger.
Battery lasts 10 days. The wireless charging dock tops you up in 120 minutes. The titanium is grade‑5 aerospace alloy with a diamond‑like carbon (DLC) inner coating that won't scratch, won't turn your finger green, and won't corrode in pool chlorine or sea salt.
90 minutes. 10 days.
Drop the ring into its magnetic cradle and walk away. A full charge takes 90 minutes and lasts up to 10 days of continuous sensing — longer if you're not a heavy sleeper or athlete.
The dock itself charges over USB-C. One cable at your desk keeps both the ring and the case topped up.
Reads you continuously.
Six LEDs and three photodiodes sample your pulse waveform 100 times a second, around the clock. The infrared thermopile reads skin temperature to 0.02 °C. All of it streams silently to the AI — no taps, no prompts, no reminders to breathe.
The finger is the best place on the body for optical sensing. Capillary density is 40% higher than the wrist, contact never slips during sleep, and there's no tendon movement to corrupt the signal.
