The core screen — task list on the left, colour-coded timeline bars on the right, synced scroll and a date ruler on top. A visual schedule built for the jobsite.
On a real build the schedule changes every week — a wet Monday, a late frame delivery, a subbie who can't start until Thursday. Construction Gantt is a construction scheduling app for iPhone, iPad and Mac that treats change as normal: link your tasks once, and when one moves, everything after it reschedules automatically, skipping weekends and the public holidays for your country and state.
Break the job down the way you actually build: site works, slab, frame, roof, lock-up, fit-out — with sub-tasks nested up to five levels. Parent stages summarise their children's dates automatically, and status rolls up on its own: if waterproofing runs late, the whole wet-areas stage shows late; tick the last task and the stage completes. When the job is done, save it as a template and start the next knockdown rebuild or renovation from it — the new job schedules itself from its start date.
Everything is sized for a thumb on a phone. Tap a task and six quick buttons appear: drag, add sub-task, a duration stepper that re-plans the whole chain, status, camera and link. Long-press to reorder or nest. Fifty steps of undo mean no change is scary. And because the app is offline-first, a black spot on site never stops you — changes save on the device instantly and sync when you are back in coverage.
If you run residential jobs — new builds, extensions, renovations — this is a building schedule app sized for your crew, not enterprise software with a training course. Owner-builders planning their first build get the same automatic rescheduling the pros use, free to start: the Free plan includes 2 projects and 200 tasks, no card required.
