There is a paper you can cite if you use phyphox professionally.[1]

In Germany phyphox is quite popular in physics education.

However on android the sampling rate of the acceleration sensor is limited to 50/s. At least if you install through the official app store.

Good toolkit to have around. Recently used it to verify the true RPM of a system (using the accelerometer spectrum tool) against its control loop implementation.

The title was slightly editorialized for clarity.

Cool app dude
