This simple and nice app displays a graph of Acceleration vs. Time on three axes. The three components of the acceleration vector are continuously read from the currently selected sensor; they can be displayed together, on a single grid, or each component can have a separate graph. Our app (portrait orientation, Android 5..8 required) will only work on the smartphones that have at least one acceleration related sensor, hardware or software. You can use the Accelerometer app to study the Earth's gravitational field or to measure the mobile device's movements and vibrations.
-- three acceleration sensors can be read (standard gravity, global or linear acceleration)
-- free app - no ads, no limitations
-- no special permissions required
-- this app keeps the phone's screen ON
-- sound alert when a certain level is reached
-- the sampling rate can be adjusted (10..100 samples/sec)
-- custom range of the grids (100mm/s²..100m/s²)
