Timesheet - Mobile Time Tracker

Track your work hours from your browser — one click, always in reach.

Timesheet brings time tracking right into Firefox. Start a timer from the toolbar or the sidebar, switch projects in a click, and let your hours sync with your timesheet.io account across web, iOS, and Android. No more forgetting to track, no more switching apps.

Track time without breaking focus • Start, pause, resume, and stop the timer from the sidebar or popup • Pick a project and ToDo, then track with a single click • Add notes, expenses, and manual breaks to any running task • See today's progress, this week's hours, and your open ToDos at a glance

Stay on top of your targets • Live daily and weekly progress against your work contract • Get reminded when you approach or reach your target hours • Break reminders when you've worked long enough to owe a pause • A toolbar badge shows today's tracked hours at a glance

Track honest hours, automatically • Idle detection notices when you step away while the timer runs and offers to discard that time • Everything stays in sync with your timesheet.io account, so the hours you track here show up everywhere

Built for the way you work • Light and dark themes that follow your system • Available in English, German, Spanish, and French • Clean, fast, and keyboard-friendly
