Gantt Project Planner

Gantt Project Planner helps you build clear schedules, track progress, and stay aligned—without a subscription or cloud account. Plans live on your device, so you can review timelines and update work wherever you are.

Create a work breakdown, set durations and dependencies, and see dates recalculate as the plan changes. The Gantt chart and task list stay in sync, so you always know what drives the finish date.

BUILT FOR REAL PROJECT WORK
• Work breakdown structure (WBS), summary tasks, and milestones
• Automatic scheduling with dependencies, lag, and task constraints
• Critical path, total float, and schedule diagnostics
• Work, material, and cost resources with assignments
• Daily resource load with overload highlights
• Baselines, status date, actuals, and earned-value indicators (SPI/CPI)
• Search, filters, sorting, and grouping to focus on what matters
• Light and dark appearance

WORK ON THE GO
Use the mobile overview to check today’s work, milestones, and project health. Update percent complete, actual dates, and notes when you are away from your desk. Continue detailed planning on Mac or Windows with the same project files.

OPEN FORMATS, LOCAL FILES
Save in the native .gan format, and exchange plans with CSV, Microsoft Project XML (MSPDI), MPX, Planner XML, and Excel (.xlsx). Export a Gantt view to PDF or PNG when you need a shareable snapshot.

Privacy-friendly by design: core planning works offline and does not require an account. Your project data stays under your control.

Whether you manage a small team schedule or a detailed delivery plan, Gantt Project Planner keeps the timeline readable, the schedule explainable, and your files portable.
