Grindstone review
A focused Windows tracker with free core features and paid team synchronization.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Grindstone is a time-tracking application for Windows users who want to record work against jobs, tasks, goals, and other work items. Its stopwatch tracking uses time slices with start, end, duration, and notes, while configurable properties and list values help organize different kinds of work. The free core application also includes estimates, due dates, completion dates, filtered and monitored views, charts, tabular graphs, and data export. It suits individuals and small teams that need focused desktop tracking rather than a broad, multi-platform business suite.
Pricing separates the standalone application from team synchronization. The core Grindstone app is presented as free, and the published pricing includes a 30-day free trial. Grindstone Sync Cloud costs $5 per user per month, billed monthly, and adds cloud-hosted team synchronization, live shared time tracking, and a REST Web API. Grindstone Sync Server costs $10 per user per month, billed monthly, and provides customer-hosted deployment, on-premises data, and team synchronization. These paid tiers are relevant when shared tracking or deployment control matters; individual users can stay with the free core app.
Its strongest fit is a Windows-centered workflow that values local tracking, structured work items, and reporting views. Team synchronization adds permissions and live shared data, while the API supports access to synchronized team data. The product remains deliberately narrow: its platform coverage is Windows, API, and self-hosted deployment, and its stated positioning does not center on billable tracking or approval workflows. Choose Grindstone for lightweight desktop tracking with optional synchronization; choose an alternative if broad platform coverage, extensive integrations, or formal billing and approval processes are central requirements.
