Klok review
A broad, free time tracker for small teams, with limits on active work and integrations.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Klok is a browser-based time-tracking tool for freelancers, independent workers and small teams. It records live or manual time against clients and projects, supports billable and non-billable statuses, and stores rates and notes. Calendar editing, timesheet views, scheduled client reports, CSV and PDF exports, and invoice drafts from checked time and expenses give it a wider scope than a basic timer. The free plan covers one active client and one active project, making it a practical starting point for focused work or a small operation.
Pricing is straightforward. Free costs £0 per workspace and includes every current feature, with no payment card needed, but it limits active clients and projects to one each. Pro costs £7.99 per workspace per month when billed monthly, includes every current feature, and removes the stated plan limits for active clients and active projects. A 30-day free trial is also listed. For a freelancer with one main client, Free may cover the full workflow; teams managing several clients or projects need to weigh the per-workspace Pro price.
Klok’s strongest fit is its combination of tracking, reporting and invoicing across web, Windows, macOS, iOS, Android and Chrome extension access. Square supports the listed invoice workflow, while scheduled client reports can include optional PDFs. The product also lists offline tracking and data export. However, it does not provide a timesheet-approval workflow, and some native apps and extensions are described as testing or development rather than generally released. Choose Klok for accessible project and billable tracking with invoice preparation; consider an alternative if approval controls, a broader integration ecosystem or fully released companion apps are essential.
