Single window for all views
The three views are continuously synchronized. Entering values in the spreadsheet is instantly reflected in the graphic view.

Frequently Asked Questions

Is it possible to import M! 2.0 files?
Yes. M! 3.0 is able to import legacy files from M! 2.0. However, since M! 3.0 saves data in a new format, it's not possible to read M! 3.0 files with M! 2.0.

Will there be a Windows version of M! 3.0?
Sorry, no. We have currently no plans to release M! 3.0 for Windows.

Does the iOS version have the same functionality as the Mac versions?
The iOS version of M! is able to read and write M! 3.0 files. Editing in the graphic view is possible, but due to limitations of the touch interface not as full featured as in the Mac version. Data entry and analysis in the spreadsheet, however, are the same as in the Mac/PC version.
