Smartphone app not good enough to track blood pressure in pregnancy

High blood pressure in pregnancy is a prevalent problem, especially in a country like Malaysia where there is a significant portion of the population with hypertension.

A smartphone app may not be an effective method of measuring blood pressure in pregnant women, a small experiment suggests. 

Researchers tested an experimental smartphone app that uses the phone's camera to monitor blood flow in the index finger with each heartbeat. They compared results from the app to traditional blood pressure measurements taken on 96 occasions in 32 pregnant women.
