Workback
Delivery doesn’t move.
A workback calendar with a real engine under it. Drag one bar and everything downstream reflows — around weekends, around July 4th — and recoils off a locked delivery instead of sliding past it. Free forever. No account.

What it does
The mechanics are the proof.
- 01
Locked milestones. Lock the delivery and the schedule compresses against it. Bars recoil off the diamond; they do not slide past it.
- 02
Workdays, not calendar spans. The engine counts working days. Bars split around weekends and holidays instead of pretending Thursday to Monday is two days.
- 03
Drag and it recalculates. Move one phase and the downstream shifts with it — with undo. No re-spacing thirty boxes in a deck.
- 04
Share with a link. One link, no account on the other end — everyone on the link works from the same calendar. PDF export when it needs to be paper.
The chain
How it connects.
The workback is where most jobs start — it is free, and the dates you settle here flow downstream when the job turns real.
Start the schedule. It’s free.
No account, no trial clock. When the job turns real, the same thread becomes the bid, the call sheet, the cash flow.
