When mind is at peace, body responds in the same tone. Contrarily, a little anxiety or worry may upset the peace of mind and body, leading to faster heartbeat, taut muscles, high or low blood pressure, abnormal hormone secretion, and over sweating. These are the common symptoms of stress. These may, in turn, lead to serious health issues, as well as psychological disorders, such as insomnia (sleeplessness), anger, and tendency to commit suicide. Nowadays the ratio of suicide is on the increase on a day-to-day scale. To overcome all these problems, and cater to human right to enjoy an environment of peace and quiet for better mental and physical performance, the authors have developed an Android-based offline, multi-functional mobile application: Relax Player App. It panoramically arrays natural sounds, animal sounds, instrumental music, white noise, and brain soothing melodies to relax and freshen up user's ears and mind. It also has in-built mechanism to create one's own melody by mixing these sounds, adding to its appeal.
