Chronos Timetracker is a free, open-source Mac desktop application that brings native time-tracking directly into your JIRA and Trello workflows — no browser tab juggling required.
What is Chronos Timetracker?
Chronos Timetracker is a desktop client for JIRA and Trello that lets you start a timer against any issue or card and log that work back to the source project management tool automatically. It sits in your menu bar, connects to your boards, and keeps your logged hours in sync without you ever having to manually fill in a timesheet.
I've spent too many evenings reconstructing hours from memory because I forgot to log time in JIRA before closing my laptop. Chronos plugs that gap by making the timer the first thing you click when you pick up a ticket — not an afterthought at the end of the day.
What does Chronos Timetracker do best?
Chronos earns its keep through frictionless one-click time logging directly against a JIRA issue or Trello card — no copy-pasting ticket numbers, no context-switching to a separate time-tracking dashboard. Pick your issue from the native interface, hit the play button, and your worklog is written back to JIRA (or your Trello power-up) when you stop.
- Issue-native timers — timers live on the issue itself, so worklogs make sense in context
- Offline resilience — logs queue locally and sync when your connection is restored
- Menu-bar access — current timer and quick-switch controls are always one click away
- Worklog history — a local view of what you've logged without opening JIRA
Where dedicated time-trackers like Toggl or Harvest require a separate integration to marry hours to tickets, Chronos is built around the ticket from the start. That's a meaningful difference for a solo developer or a small team billing against JIRA epics.
Is Chronos Timetracker free?
Yes — Chronos Timetracker is completely free to download and use. It is published as open-source software on GitHub under the web-pal organisation, which means the source is auditable and community contributions are welcome. There is no paid tier, no feature gating, and no subscription.
The trade-off is that active maintenance depends on community momentum rather than a commercial roadmap. If you hit a bug, the right move is to check the GitHub issues and, if needed, open one — the project has historically been responsive to community reports.
Who should use Chronos Timetracker?
Chronos is a natural fit for freelancers and agency developers who bill clients by the hour and live inside JIRA or Trello all day. If you already track time with a tool like Toggl Track, Harvest, or Timing, you're adding an extra sync step that Chronos eliminates entirely. It's also well-suited to distributed teams where project managers expect JIRA worklogs to be accurate without chasing people for updates.
It is less useful if your team doesn't use JIRA or Trello — there is no generic timer mode or integrations with Linear, Asana, or Monday. Power users who need detailed reporting, invoicing, or cross-project analytics will also want to pair Chronos with a dedicated reporting layer, since its own history view is intentionally lightweight.
What are the best Chronos Timetracker alternatives?
The closest native Mac alternatives depend on what you need beyond basic logging. Timing is the most polished automatic time-tracker on the Mac — it records every app and URL passively and lets you assign time retroactively, but it has no direct JIRA write-back. Toggl Track has a solid Mac menu-bar app and a JIRA integration, though it goes through Toggl's cloud rather than writing directly to JIRA worklogs. Harvest is similar — excellent invoicing, JIRA connection via third-party glue. Timemator automates tracking with rules but lacks a project-management integration. If you want zero friction between starting work on a JIRA ticket and having accurate worklogs at sprint close, Chronos is the most direct path; if you want richer reporting or invoicing, pair one of those alternatives with JIRA's own time-tracking API.
