TickTick was launched by Appest in 2013 starting from the China market, an all-in-one cross-platform productivity app integrating to-dos, Pomodoro, habit tracking, calendar, kanban and notes, with tens of millions of users and Premium around $35.99/year.
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.
