Primary goal: Gather data to provide feedback (and immediate bad conscience) regarding time management - both to decrease slack permeating and diluting (or just postponing) worktime, and to allow for focused time for intense relaxation.
Comparatively low priority for now: Health/exercise/mood tracking. (Too many solutions focus on this.)
Constraints: Linux, ideally open source + no cloud. Possibly Android, but I hate using my phone.
Physical device to collect work/slack info with no overhead + automated data acquisition. TODO
