Du-Sung Technology's StressViewer lays out a way to calculate your level of stress. It tracks your heart rate directly from your smartphone and - considering your age - submits it to their own stress scale to output some interesting results.
Once the test is done, it displays in a understandable way your physical and mental stress, ANS Balance Inspection and measurements results (maximum, minimum and average heart rate). Of course, how the app sets the value of their own scale is a mystery, an internal algorithm. The reliability of the test is thus questionable.
However, it's true that's possible to calculate your level of stress (and perform many other diagnoses) by tracking and monitoring your heart rate periodically.
Finally, StressViewer displays a history graph, able to track the last 15 tests.
The app is set in a minimalist yet neat interface. Fair enough.
We are missing though some features like reminders to run the test periodically, results depending on personal features (age, weight, daily activity) and sharing options.

!!! Mobile Stress Measuring Application !!!
By using Smartphone's camera and flash, this app measures heart rate,stress level and autonomic nerve balance. This app will help you managing stress efficiently.
(1) Heart rate measurement in real-time
-Minimum/Maximum/Average heart rate measurement
(2) Stress measurement
-HRV(heart rate variation) graph display
-Automatic nerve balance result
-Physical/mental stress level
-Accumulated data display
2) Application use
-By measuring heart rate,autonomic nerve balance and stress level by using a smart phone, user can efficiently manage stress frequently.
-It is a smart health care and mobile health care system, anywhere at any time you can check the status of your stress simply.
3) Method of measurement and principle.
-Measurement by using one of the PPG (Photoplethysmography) methods.
There are two types of pressure, systolic and diastolic at the heart, therefore the peripheral vascular, amount of blood flow, and volume of blood vessel changes. StressViewer measures the amount of penetration of light by using the camera image that shows the pattern of heart beat.
The smart phone’s flash light will be exposed at the end of the user’s finger and the amount of blood flow can be measured because when the heartbeat occurs, the amount of blood flow in the peripheral blood vessel changes which is detected by camera on smart phone.
-Only works at Smartphone camera with a built-in flash
-Do not shake finger during measuring
-Do not press the camera and flash too hard
-This application is not for professional medical diagnosis
5) Introduction of Du-Sung Technology Corporation and guide on released app.
-Du-Sung Technology have developed and manufactured the wireless heart rate monitor, moreover, we have earned the respect in accuracy and quality of products through many years of knowhow in the field of wireless heart rate monitor.
Currently we have anounced two apps which are “StressViewer,” and “CardioPlanner.”
“StressViewer” is very easy-to-use app since it measures the current stress rate without any other instruments, but with only smart phone with a built-in flash camera.
And the app, “CardioPlanner” is the chest-belt typed wireless heart rate monitor that can be connected with smart phone by bluetooth to measure, so user can obtain more accurate workout data.
“CardioPlanner” accurately measures heart rate, number of step, exercise route, exercise distance, consumed calories, measurement of stress, etc, and the result can be uploaded to Web, so this app will help users to exercise systematically.
