Understanding how Doori measures heart signals to support daily health awareness
At the heart of Doori’s technology is one clear idea. Heart health should not be checked only once a year or only when something feels wrong. It should be understood every day. Doori helps people see how their heart responds to stress, activity, sleep, and routine life.
Doori uses a method called photoplethysmography, also known as PPG. While the name sounds technical, the process is simple. Doori sends a small light into the skin and measures how much light comes back. As blood flows with every heartbeat, the reflected light changes slightly. Doori reads these changes to understand heart rate and blood flow patterns.
Doori sends this information to the mobile app using Bluetooth Low Energy. This allows the data to sync easily without using much battery. The device measures key parameters like Heart Rate, Oxygen Level, Blood Pressure and HRV and sends it to the mobile app. The app shows patterns and trends over time in a simple way which helps users understand the real issue and take steps towards improving their overall heart health.
Blood pressure is usually checked using a cuff. Doori works differently. It tracks how blood pressure changes by reading blood volume changes through the finger. Instead of focusing on just one number, Doori helps people see how their blood pressure changes over time, which is more useful for everyday health awareness.
Data safety is also an important part of Doori. All information is kept secure and users control what is shared. Doori also avoids showing misleading results when the data quality is low, and highlights confidence levels so users understand how reliable a reading is.
What makes Doori valuable is not only the technology, but how it helps people understand their own body. Doori does not replace doctors or medical tests. Instead, it supports daily awareness by showing how stress, recovery, and heart health change across days and weeks.
In a world where most people check their health only during illness or annual check ups, Doori helps create a shift. It encourages people to notice early signs, understand patterns, and make better lifestyle choices before problems grow.
