Re-syncronising data from multiple devices
Unfortunately, system times on smartphones can be quite out of sync, up to several seconds. Sites like display how much the clock is off. You should take the result with a grain of salt: the rather simple algorithm is described on the “about” page…

Utilising these offsets, you might get a better time synchronisation. We might include something like this in future phyphox versions, however, we certainly need to do some research on the best way – and privacy protection.

There also appears to be an offset in the amplitude that could have many causes, hardware and software. Please note that “linear acceleration” is a virtual sensor that typically includes data from gyroscope and magnetometer, so-called sensor fusion.
