iCal vs. ActiveCollab

iCal is Apple's personal calendar application designed to help users efficiently manage their schedules, appointments, and tasks. It offers multiple calendar views—daily, weekly, and monthly—allowing users to oversee their activities at a glance. With iCal, users can create and manage multiple calendars within a single unified window, making it easy to identify schedule conflicts and available time slots. The application supports online calendar sharing through a .Mac account, enabling collaboration with colleagues, family, and friends.

ActiveCollab is the work management platform for agencies and service businesses — from the first task to the paid invoice, in one place. Plan projects in List, Kanban or Gantt view, track time on every task with a built-in stopwatch, manage workload and capacity, and turn tracked time into estimates, invoices and profitability reports. Budgets, expenses, billable rates and online payments (Stripe, PayPal) are built in — no bolt-ons.
