Automatic, private time tracking that turns hours into client profitability
Rize records work sessions in the background on macOS and Windows, with no timers to start and no timesheets to reconstruct from memory.
Hours are attributed to the right client and project automatically, with each person reviewing and approving their own time before the team sees it.
Margin by client, project and person, plus retainer burn versus plan and capacity views that flag over-servicing before the month closes.
No screenshots required. By default Rize reads only app name, window title and URL, and personal activity is never shared with the team.
