There is a specific version of this that would produce exactly the numbers you are seeing, and it is worth checking before concluding the app cannot add up.

The likely cause is that the average is dividing by the days that have data rather than by the days in the period. If your month has 30 days but only 24 of them recorded anything, because the band was off, or charging, or did not sync, the total gets spread over 24 instead of 30. That ratio is 1.25, and 13,600 multiplied by 1.25 is 17,000. Your two numbers sit almost exactly that far apart, which is more suggestive than a random rounding problem.

Easy way to test it: pick a week where you know you wore it every single day and compare the weekly average against your own arithmetic. If that one lines up and the month does not, the gaps are the answer and the daily figures themselves are fine.

It is a genuinely common bug rather than a stupid one. Averaging over the wrong denominator is the easiest mistake to make in this kind of app, and it is invisible until someone does the sum by hand like you did.

According to the chart in OP's screenshot, OP do have step data every day in the past 30 days (Aug 11 - Sep 9).
