The Acceleration PWA uses the accelerometer sensor in a cellphone or other mobile device to measure motion. The app displays and records the vector acceleration components.  To record data, set the time interval [start, end] and press the Record button. Recoded data can be copied to the clipboard and pasted into another app, such as a spreadsheet, for further analysis.

A Progressive Web Application (PWA) is a type of mobile app that is delivered through the web, that can work off-line, and that can be installed on a user's home screen. PWAs are built using industry-standard web technologies including HTML, CSS and JavaScript.
