For obvious reasons smart watches are limited to what the sensors can tell them….
Friday I visited the Minatur Wunderland in Hamburg . I walked around in there slightly over six hours from 16:15 to about 22:20 to my feet were killing me – I could easily have used their full opening hours to 01:00, weren’t it for the feet.
But as the walking in a fun exhibition, with many many details, is very slow, and thus not with swinging arms, the smart watch barely registered that I had walked at all. Only a few hundred paces an hour in that period. It registered the walking earlier that day, as well as the walk back to the hotel just fine.
Not to criticise it or anything, just as an example of how incorrect smartwatch info can be… And that they ALWAYS shall be read with a HUGE pinch of salt.
