🗓 Schedule
Phases, dependencies, and the critical path on one timeline. If a task runs late, everything that depends on it moves later. Moving a task earlier does not pull the others with it.

FAQ

Common questions

Does it really work without the internet?
Yes. Once GanttOWN is installed, you can open, edit, and save a project with no connection. The plan is a .gantt file on your Mac. There is no cloud account for the project itself.
Does GanttOWN ever need an online connection?
Only to activate or deactivate a license, and to check for updates. Day-to-day planning stays on your machine. You will want a connection the first time you set up a license or move it to another Mac.
What does "one-time purchase" mean exactly?
You pay once. There is no monthly fee and no renewal. Solo keeps bug and security fixes for the version you bought. Team and Business also include later features.
Can my team collaborate on the same file?
On Team and Business, save the .gantt file in a shared folder. While someone has it open, the next person can open it read-only. A password decides who can sign in. The password is a lock, not encryption, so keep a confidential file in a protected folder.
What's the difference between the tiers?
Solo is $49 for up to 5 people, with one shared password and full edit access. Team is $149 for up to 20, and Business is $299 for up to 150. Team and Business add PM and member roles, separate passwords, inboxes, date-change approvals, a project log, and an audit trail.
Mac or Windows?
Mac is ready today. GanttOWN needs macOS 13 or later, runs on Intel and Apple Silicon from one download, and is notarized by Apple. Windows is in progress. Leave your email on this page and we will send one note when it ships. A license key works on either platform.
Can I import my existing plans?
Yes. Import Excel (.xlsx and .xls), CSV, or a Microsoft Project XML file. That brings across phases, owners, progress, dependencies, and milestones. A .mpp file needs File → Save As → XML in Microsoft Project first. You can export Excel, a PDF report, or a PNG, and you can print from the app.
Does it support phases and dependencies?
Yes. Group tasks into phases that show their combined progress and collapse with one click. Link tasks with dependencies (with optional lag in working days) so late work pushes everything after it, and the critical path is highlighted automatically. Schedules can skip weekends and holidays.
Is there a trial, or can I get a refund?
Instead of a limited trial, you get the full app with a 14-day refund window. Buy any tier, use every feature on a real project, and if it isn't right for you, email [email protected] within 14 days. We process refunds within 24 hours, no questions asked.
