Comfortable continuous BP band
A wrist bracelet that estimates blood pressure optically around the clock — the first cuffless BP monitor cleared by the FDA for over-the-counter use (July 2025) — with monthly cuff calibration. Already sold in Europe (as Hilo); the US Hilo Band arrives in 2026.
What it measures
Optical (PPG) cuffless blood-pressure estimates throughout the day and night, plus heart rate, with periodic calibration against a traditional cuff.
Regulatory status
FDA 510(k)-cleared in July 2025 for OTC use — the first cuffless BP monitor cleared OTC in the US. CE-marked Class IIa in Europe (sold as Hilo).
Validation & accuracy
Demonstrated accuracy across skin tones and postures with monthly cuff calibration; cuffless BP accuracy more broadly remains debated.
Data control & export
Raw data: restricted — readings live in the app with trends to share; no open developer API or raw export documented. API: none.
Wearability & battery
A light, comfortable wristband worn continuously, taking passive BP readings without inflation; far more wearable than a cuff.
Cost & access
Sold in Europe now; US Hilo Band available in 2026. Hilo uses a subscription/membership model alongside the band.
Who it serves
People who want continuous, cuff-free blood-pressure trends they can wear all day.
Who is left out or burdened
US availability not until 2026; needs monthly cuff calibration; app-locked data; subscription model.
✓ Strengths
- First FDA-cleared OTC cuffless blood-pressure monitor
- Comfortable all-day, cuff-free continuous readings
- CE-marked and proven with 130,000+ users in Europe
- Accuracy demonstrated across skin tones and postures
✕ Weaknesses
- US Hilo Band not available until 2026
- Needs monthly cuff calibration
- Subscription model; app-locked data, no API
- Cuffless BP accuracy still debated
70
Why this clinical score. A genuine FDA OTC clearance for cuffless BP is a real first and clinically meaningful for trend monitoring; held mid-axis because cuffless accuracy is still debated and it needs cuff calibration.
52
Why this empowerment score. App-locked data, a subscription model, no open export, and 2026 US availability keep empowerment mid-low.
66
Why this everyday score. Genuinely comfortable continuous wear — its big advantage over a cuff — once it reaches the US.

Reviews & coverage
Coverage is optimistic about effortless, cuffless background BP monitoring but consistently flags that it needs cuff calibration and isn't yet a validated diagnostic replacement. Reviewers call it promising and worth watching as evidence grows.
