Meeting Maker is a cross-platform personal calendar and group scheduling software application from PeopleCube. First released in 1991 for Macintosh by ON Technology, support for other platforms followed in 1993 with Meeting Maker XP. Alongside Windows and Mac, native clients were released for OS/2 and Solaris and later also for other platforms (HPUX, Linux). Some support was introduced also for mobile platforms like Apple Newton, PalmPilot and Windows CE. Although powerful, its user interface - aiming at uniformity across multiple platforms - was criticized as weak and not supporting all features of target platforms.
