One timer. Every device you actually use.

Start a timer on your laptop, stop it from your phone, and see the same running entry on both. WorkingClock tracks hours by project, task, tag, and client, then turns them into reports you can hand to a client or a manager without cleanup.

Projects, tasks, tags, and clients, kept apart

Group time by project and task, label it with tags, and attach it to a client so an agency running four accounts never mixes up whose hours are whose.

Reports a client can read

Filter by project, tag, or date, then export to CSV or a branded PDF.

Reminders when a timer's still running

Left the timer on after leaving your desk? WorkingClock nudges you before hours pile up on the wrong entry, on whichever device you last used.

Client redesign has been running for 3h 40m. Still working on it?

Share a single project with a client as a read-only guest, no seat, no full account, just the hours on that one project.

Guest access

The same running timer, on whatever you have in hand

Web, iOS, Android, and a native desktop tray app all read from one account. Start on your desktop before a call, stop it from your phone on the walk out, and the hours land in the same timesheet.
