When I Work was founded in 2010 in the United States as an employee scheduling and attendance tool for hourly and shift-based teams. Scheduling, Web/mobile/kiosk clock-in, hours and overtime calculation, and team messaging combine so the free plan already supports basic management for small shift teams.
TSheets is the time tracking brand Intuit acquired in 2018 for approximately $340 million and the predecessor of QuickBooks Time. GPS clock-in, geofencing, scheduling, and timesheets combined with seamless QuickBooks integration make it a common choice for US-style attendance and payroll.
TrackingTime was founded in 2012, headquartered in the United States with an Argentine operations team, as an all-in-one time tracking and project management SaaS. Real-time timing, calendar views, and team performance analysis combine so the free plan already supports basic hour management for small teams.
