Three lanes, one schedule conversation
Track client actions, contractor work, and milestone commitments in one shared visual surface so dependencies read the way the job actually progresses.
Target-date planning
Keep the plan clean. Show the slip clearly.
swimlane is built for schedules that start from committed dates, dependency lag, and lane ownership. Save the real planning model in a native .swimlane file, keep Excel optional, and let the chart surface the actual delay without rewriting the baseline.

Native file
Save the planning model, not a flattened copy.
The planner keeps the authored target dates and the current schedule state separate, so round-tripping does not erase visible slip.
About
Made for live scheduling, not just reporting after the fact.
swimlane keeps the plan understandable while multiple teams push on the same timeline. The chart and task table stay in sync, target dates remain visible, and the file format is designed around the planner instead of around a spreadsheet compromise.
Keep the baseline honest
Target dates stay authored. Slip is calculated in the schedule instead of being baked back into the saved file each time somebody clicks save.
Use Excel only when you need it
Import existing workbooks, export a copy for outside systems, and keep the operational source of truth in the planner's own format.
Table and chart stay synchronized
Edit in bulk when needed
Features

Why use the Windows version?
The Windows build gives you the packaged desktop experience with local file handling, while preserving the same planning surface and data model.
