AccDataRec is an Android application developed by acoelhosantos. It falls under the category of Business & Productivity and is available for free.

The application is designed to record accelerometer data (x, y, z components) in m/s^2 (SI unit) and save it to the device's memory storage. The recorded data is saved in TSV (tab-separated values) format with a user-specified filename. Each entry in the data consists of "counter \t timestamp \t x \t y \t z \t filename \n". To prevent data loss, the application periodically writes the acceleration data.

AccDataRec is a useful tool for anyone working with accelerometer data. It provides a simple and efficient way to capture and store acceleration measurements. With its user-friendly interface and accurate recording capabilities, this application is a valuable asset for research, analysis, and various other applications that require accelerometer data collection.
