A time tracker is computer software or a web app that allows teams, managers, and freelancers to measure time spent on tasks and projects. It is used in many industries (law firms, accounting, creative agencies, IT teams) for settling up with hourly workers and billing clients for work. You can integrate a time tracker with third-party tools for project management, accounting, customer service, to-do lists, and many more. Speaking shortly, a time tracker helps you understand which practices in your business lead to time waste. With this knowledge, you can reduce bad practices and optimize workflow.
