In the very near future, you’ll be able to download the Biospectal OptiBP app to your Android phone (the iOS version will be released later this year) and
use its camera to optically check your blood pressure.
The results are faster than, and just as accurate as, a blood pressure cuff, and they have been validated in peer-reviewed studies, with regulatory approval in the United States slated for later this year. It’s already being used globally, with the support of the World Health Organization and the Gates Foundation. And most importantly, the app has been tested on the hardware that patients actually own, like 5- to 10-year-old smartphones.
