No, the Aktiia app displays the average of all the BP measurements taken within 2h time slots. Your blood pressure naturally changes during the day and the night depending on your physical activity, body position changes, and stress levels. However, the fact that your blood pressure rises after running to catch a bus does not mean that you are hypertensive in the mornings. By averaging several measurements every two hours into one BP value, Aktiia provides you with a smoother BP curve that better represents your actual cardiovascular state.
