evidence: A New App to "Uncuff" Blood Pressure Monitoring [...] "Development of a cuffless blood pressure measurement device that does not require any external calibration is the holy grail—such a device currently does not exist," Shroff said. "The research work reported in this publication is an important step in the right direction, and is also encouraging for additional work aimed at obtaining systolic, diastolic, and mean pressures." [...] "This app would be really useful in low-income settings where people may not even have existing access to blood pressure tools." Dhamotharan said. "Being able to measure blood pressure more frequently would allow an individual to track any significant changes in blood pressure, monitor for hypertension, and be able to manage their conditions with that knowledge."
