"Instead of applying pressure to your blood vessels, the Hilo band uses the same photoplethysmography (PPG) optical sensors that are already in most fitness trackers to analyze the pulse shape of the arteries under your skin. It then uses its proprietary algorithm to measure your blood pressure multiple times a day when you're at rest."
"Continuous blood pressure monitoring, especially while walking, sleeping, or lying down, is the gold standard for assessing your cardiovascular health. If your blood pressure doesn't go down while you're sleeping, that's a strong indicator that you might have cardiovascular disease. Unfortunately, it's really hard to relax if something is repeatedly squeezing your arm while you're trying to sleep."
"The Hilo was FDA-cleared in 2025, has been tested and reviewed in multiple clinical-grade studies over several years, and meets the ISO 81060-2 standard for validating the accuracy of blood pressure monitors."
Hilo is a wearable band that measures blood pressure using photoplethysmography optical sensors, the same technology found in fitness trackers, rather than traditional cuff inflation methods. Unlike devices like Omron Evolv and Aktiia that embed electronics in the cuff itself, Hilo analyzes pulse shape through optical sensors to measure blood pressure multiple times daily during rest. The device has been FDA-cleared, clinically tested, and meets ISO standards for accuracy. A key advantage is enabling continuous blood pressure monitoring during sleep and rest without the discomfort of repeated cuff inflation, which is important since non-dipping blood pressure during sleep indicates potential cardiovascular disease.
