      Apps and switching

      Which apps are used, for how long, and where people switch.

      Continuous pieces of work, and data copied from one tool into another.

      activity.* · work.day.summary

      Time and activity

      Active, idle and away time. Counts, never keys.

      Privacy by design

      Your product gets the signal. Not the screen.

      Processed on the Mac

      No cloud in between.

      Personal apps protected

      Passwords, banking, health: off-limits.

      Every signal a switch

      Send only what you need.
