Currently, the Apple iPhone or any other smartphone can measure the blood pressure of the user. But the user needs to use an external device to actually measure the recordings and then send it to the device. The new report revealed that the new technology uses a short selfie video to measure the blood pressure. 

What is more interesting is that the report states that this is accurate about 95% of the time. This could be a life-changer as high blood pressure does not showcase any symptoms. 

Researchers at the University of Toronto in Canada and Hospital of Hangzhou Normal University in China posted a proof-of-concept video showcasing a user measuring his blood pressure using a short selfie video. 

The phone takes about 900 images in 30 seconds to read the blood pressure. The research team took the measurements and then used them to train a machine-learning algorithm which gave them over 95% accuracy.
