A lightweight utility in order to quickly and securely record CoreMotion gyroscope and accelerometer data together with audio data. CoreMotion data can be downloaded as a CSV (comma separated values) file and audio can be downloaded as a standard m4a file. Your data is only available on your device. Data will not be shared with others and will not be uploaded centrally. Data can then be used for further processing, mostly for machine learning (ML) / deep learning purposes. Key highlights: - Record gyroscope and accelerometer data directly from your phone's CoreMotion module - In parallel, record audio from your phone's microphone - Assign a label to each recording which can be later used in your machine learning workflow - Choose the frequency of the data to be captured per second - Download the captured data or send it via email - Further process the data within your favorite machine learning environment, e.g. using Python
