What exactly are you referring to? If it is timestamps: perhaps, they treat start und stop differently? Hm, on my iPhone the data in Science Journal is not at full rate, so there could be some averaging – and timestamps are artificial anyways then.
Look at the image here . I am recording the magnetic field in Phyphox and the Science Journal.
Why the values in H2 and H9 are different from M2 and M3?
Recording the data using system time is very helpful when I can sync data from two independent phones and do time analysis. However, getting the discrepancy in raw and metadata will leave a margin of error here.
H15 is the recording from the Science Journal app where it starts with 0. Perhaps the science journal app records only the system time data and then gives the relative time. It is a little gray area where I will never know if there is a discrepancy in Science Journal metadata and Raw data since it doesn't give one in one file.
Could that be a limitation of my phone?
