Step by step
- Save the file where Files can see it. Put the .mpp in Files or iCloud Drive. Cloud placeholders need downloading first, so open it once while you still have signal.
- Choose it in GanttPeek. Tap Choose MPP File and select the schedule in Apple’s document picker.
- Read the plan. Move through tasks, hierarchy, dependencies, resource identities and the Gantt timeline.
- Share a readable extract. Use the More menu to share a CSV of tasks or a PDF schedule report.
Why an on-device parser matters on iPad
- Site offices, client meetings and travel are exactly where you need the plan and where a connection is least reliable.
- A converter-backed viewer shows a spinner without signal; a local parser opens the file it already has.
- No Microsoft account and no sign-in wall between you and a schedule someone emailed you.
- A built-in sample project lets you check the app before opening anything confidential.
Honest limits
Read this before you rely on it. GanttPeek states what it does not extract rather than presenting a partial read as a complete one.
- Files must be no larger than 50 MB on iPhone and iPad. iOS or iPadOS 17 or later is required.
- Read-only. Editing a schedule still requires Microsoft Project.
- Password-protected MPP files are not supported.
- Baselines, progress, constraints, notes, calendar exceptions, custom fields and resource costs are not extracted.
Questions
Can iPad open MPP files natively?
No. iPadOS has no MPP reader, so the file shows as a generic document until an app with an MPP parser opens it.
Does it work offline?
Yes. Parsing is local, so a downloaded schedule opens with the iPad in airplane mode.
Is there a free way to try it?
GanttPeek includes a built-in sample project and one real project at no charge.
Can I share the schedule with someone without the app?
Export a PDF schedule report or a CSV of tasks and share that instead of the MPP.
