[Avodah] Fitbit on Shabbos

[Marty Bluke via Avodah]

This is many ways similar to the use of electronic water meters on shabbos.
The meter has no external display that changes and all it does on Shabbos
is record how much water you are using. The Charedi poskim in israel have
all assumed that it is absolutely forbidden. You can see the kol korehs
