The startup Vital Signals he announced Signal Ringa new smart ring designed to monitor blood pressure by offering measured values directly, without requiring periodic calibration via a traditional arm monitor. The company claims that this technology represents a step forward compared to many of the solutions available on the market today.
Hypertension is often referred to as a “silent killer” because it can cause damage to the heart, brain and arteries without showing obvious symptoms. In many cases the pathology is discovered only after serious events such as heart attacks or strokes. Hypotension can also pose risks, but high blood pressure is generally considered the most dangerous condition. For this reason, constant monitoring of blood pressure values is required particular importanceespecially in older people or those considered at risk.
With the arrival of watchOS 26, five Apple Watch models are capable of monitoring blood pressure. It’s about Apple Watch Series 9, Series 10, Series 11, Ultra 2 and Ultra 3. However these devices they do not show actual pressure valueslimiting itself to reporting any indications compatible with possible hypertension. A similar approach is also adopted by other wearable devices such as Oura Ring.
There’s a new smart ring: the Signal Ring, and its focus is entirely on taking your blood pressure and giving you actual systolic and diastolic readings, which makes it different than Apple and Oura. @chriswelch takes a deep look. https://t.co/LiqWm28On4

The price and philosophy behind Signal Ring
There are already products capable of providing complete blood pressure measurements, but they require periodic calibration using a classic cuff monitor. Vital Signals claims that Signal Ring completely eliminates this need.
The founder and CEO Tom Moss he says he decided to create the company after risking his life due to undiagnosed hypertension. According to Moss, consumers today have few truly practical solutions to accurately know their blood pressure values.
Signal Ring will be available in pre-order priced at $399with deliveries expected in October. The dedicated application will show both real-time measurements and the history of the data collected, without requiring any subscription. The company also specifies that the device is designed primarily for elderly people or patients who are at high risk of developing hypertension.
