Collect, Store and Analyze. AQWave Analytics - Phone is designed for anyone who wishes to understand how a human body functions from the perspective of fluid dynamics. Together with the AQWave PPG Recorder, the Analytics application easily provides information such as respiration rate, the depth of diacritic notch and sympathetic/para-sympathetic tone. This is a free beta release for your trial; we will be working hard to release versions with more analytic tools in the near future.
