Free Task Tracker & Timer
Clockify is the most popular free task tracker and timer app that lets you and your team see how much time you spend on activities.
How to track work on tasks
Set up projects and task
Create projects, categorize them by clients, and create tasks on projects. Then, all you have to do is choose a project/task, write an optional description of what you're doing, and start the timer.
Track time you spend on activities with a single click using a timer. If you forget to start timer, you can always enter the time manually later.
You can also add time you've worked on a task in a timesheet.
Track time inside other apps
Install Chrome or Firefox extension and a timer button will appear in your favorite web apps so you can track time more easily (Trello, Asana, Todoist, etc.).
Visualize tasks on timeline
Calendar view in Clockify shows you all your tracked hours and tasks on a timeline so you can see how your day looked like.
Check work hours in reports
See all your work hours broken down by task, project, and client. You can export the results in PDF, CSV and Excel, or share a live link with others.
