Lung Guru

Lung Guru analyzes your voice and breath to determine how your lungs are doing. It estimates your lung airflow volumes and also listens for sounds like wheezing and coughing that help determine respiratory health. There are five prompts: 1.) Calibration prompt to create a custom noise profile of your environment 2.) Ahh test that asks you to sustain the ahh sound as long as possible in your normal speaking voice without pausing for breath 3.) The exhale test that asks you to take a deep inhale followed by a deep exhale for a minimum of three successful attempts 4.) The cough test that asks you to cough deeply three times, and 5.) The read aloud test that asks you to read aloud a reading passage at your normal pace and volume. LungGuru provides an interactive real time user interface to help you perform the ahh, exhale and cough tests correctly. Currently, this app is accessible only to a closed test group of users who consent and participate in clinical studies.
