Manuals for the Fitbit projects I'm working on.
Note: these projects are not being actively supported anymore. Fitbit sold out to Google and Google, in their infinite wisdom, discontinued the Sense watch and released the Sense 2 that has no support for 3rd party apps. If you're at all interested in these apps get a Garmin Venu instead, better watch, still supported, and I'm actively developing apps for Garmin.
