Ah, I see. So, indeed I misunderstood you at first.
Unfortunately, I do not see a simple way to implement this in phyphox. I mean, in theory, one could use the acceleration spectrum (maybe with some more data points than the default to increase the spectral resolution) and save the times at which the amplitude in this frequency range is increased, but since you can expect other acceleration "noise" as well, it will be difficult to detect this reliably. It might be easier to just record the data and analyze it later with a script.
Also a little warning: Phyphox is not yet well designed to deal with long measurements. Depending on your phone, you might run out of memory if you try to record the entire day. If you run into this problem, you can set up a version which only records the relevant axis (I would assume it's z) and maybe at a lower rate.
