Project Online retired on 30 September 2026. Your .mpp files didn’t.

The .mpp file, native on your Mac and iPad.

Open, edit and save Microsoft Project files directly. No Windows, no virtual machine, no conversion. Lock the plan, track it every day, and send it back exactly as Project expects.

Built for the people who run the programme

Everything in the file. Nothing in your way.

Lock the plan. Track the truth.

Lock Plan saves the agreed programme as the baseline. From then on, actual starts, finishes and percent complete stay editable while the plan itself can’t drift. The chart shows slippage against the plan, and the sidebar forecasts the finish.

  • Critical path, calculated the way Project does
  • Link tasks by dragging from bar to bar
  • A grid that types like Project’s, keyboard first
iPad schedule with phases, linked tasks and the Today line
Calendars screen with day, evening and night shifts and a holiday list

Calendars that think in shifts.

Day, evening and night shifts, dragged into place. Public holidays added by country and kept as rules, so Christmas is entered once, not once a year. Save a calendar as a template and reuse it in every project.

Inspector

Dates, status, constraints, predecessors, resources, custom fields and notes for any task.

Resources

People, crews and equipment, with assignments and over-capacity flagged as you plan.

Print on one page

The system Print dialog, with a fit-to-one-page option for the site office wall.

Metal-fast Gantt

Drawn on the GPU, so big programmes scroll and zoom without a stutter.

Apple Pencil

Mark progress right on site. Pencil hover works on every control.

Any window size

Full screen, Split View or Slide Over: table and chart adapt, down to one pane.

AI, your way

We don’t sell AI credits. Bring your own.

Turn on the built-in MCP server and point Claude, ChatGPT, Gemini, Cursor or any MCP agent at your plan. It reads and edits the open programme. Every change is one step you can undo, and nothing changes while the plan is locked.

  • Claude
  • Codex
  • Gemini CLI
  • Cursor
  • VS Code
  • Any MCP agent
Settings, AI Agents: allow agents to connect, with setup steps for Claude, Codex, Gemini and others

No lock-in

Your work stays a plain .mpp. Open it in Microsoft Project tomorrow, on any machine, with nothing lost.

No account

Files live in Files, iCloud Drive, OneDrive or wherever you keep them. We never see your plans.

No cloud required

Works on a plane, in a basement plant room, on a site with no signal.

Pay for the app. Not for the AI.

Open any .mpp for free. Unlock editing when you need it. Launch pricing is announced to the launch list first.

Questions

Do I need Microsoft Project installed?

No. MPP Studio reads and writes the .mpp format itself. Files it saves open in Microsoft Project as they should.

Which versions of .mpp are supported?

Files from Microsoft Project 2010 through Microsoft 365.

Do I have to use AI?

No. The MCP server is off until you turn it on, and MPP Studio never sends your plan anywhere.

When can I get it?

MPP Studio is coming soon to the App Store for Mac and iPad. Join the launch list and we’ll email you the day it arrives.
