MoodFix studies how certain colors influence your psyche. Users will be shown a series of colors during the app’s diagnostic test. Based on your heart-rate analysis during this test, the app can prepare a customized program to help users reach a desired psychological state. You can choose a program that will help you to chill out or one that will stimulate you into action or help you concentrate on a particular task.

The first step in the diagnostic test. MoodFix will monitor your heart rate while you are watching the color sequence. Your heart rate can be monitored using a Bluetooth sensor. However, if you don’t have a Bluetooth sensor, you can use your phone’s built-in camera to monitor your heart rate.
