OmniPlan 4 Enterprise simplifies deployment for customers who wish to pay full-price for the Pro edition up front. For most customers, we recommend our normal edition — which uses in-app purchases to support free two-week trials, two levels of functionality (Standard and Pro), and upgrade discounts. The list price and the functionality of OmniPlan Pro are the same in both apps. Purchase OmniPlan once for full access to OmniPlan on your Mac, iPad, and iPhone.
OmniPlan gives you the power to manage complexity by helping you view, edit, and organize projects. Easily track your progress, manage your team, and continuously improve your processes with powerful project management features including automatic project scheduling, resource leveling, collaboration, milestones, and critical path highlighting.
View your project as an interactive Gantt timeline, a customizable project outline, or as a beautiful Network diagram. Manage simple or complex projects—all at a glance.
OmniPlan 4.9.2 contains improvements for Collaboration, Constraints, and Leveling.
• Collaboration — Changes to Project Granularity made on another device are now immediately displayed in the Inspector.
• Constraints — Constraints that are too close together now offer a solution.
• Leveling — Milestones that occur at the same time, and which are assigned to the same group member, will no longer affect computed dates of dependent tasks.
• Settings — Fixed layout of the Settings menu in the Toolbar.
