Hilo is a cuffless, continuous blood-pressure monitoring system made by Aktiia SA, a Swiss medical-technology company founded in 2018 in Neuchatel. The product traded under the Aktiia name for years before the company rebranded its consumer line to Hilo, and aktiia.com now redirects to hilo.com.
The system pairs a wristband with optical sensors, a calibration cuff used periodically, and a mobile app; the band reads blood pressure automatically up to 50 times a day by analyzing how arterial diameter changes with each heartbeat, without a traditional cuff squeeze for every reading. Hilo became the first cuffless blood-pressure monitor to receive FDA clearance for over-the-counter sale, following earlier Health Canada approval and CE marking in Europe, and the company cites clinical trials showing a systolic reduction of up to 7 mmHg after 6 months of use.
Hilo is built for people managing hypertension who want frequent, low-effort readings between doctor visits rather than a one-off cuff measurement. The band costs roughly $200 to $300 depending on region and generation, and full app functionality requires an annual membership priced around 60 to 80 British pounds on top of the hardware.
