OmniFocus requires iOS 4.0 or later. In order to use Location Reminders, you need to have iOS 5 installed, and have an iPad 2 or later with 3G or 4G.

OmniFocus 1.5.1 for iPad is a minor update which fixes Review mode regressions introduced in the previous release and improves support for iPads with Retina displays.

Review Mode

• Fixed a regression which caused incorrect labels to appear for a project’s review interval.
• Fixed a regression which caused a crash when entering Review mode for projects with a yearly review interval.

Retina Display

• Fixed display of custom Perspective icons.
• Fixed the swapped Sequential and Parallel images.
• Updated appearance of the shiny red and blue buttons in Settings.
• Updated appearance of Project, Folder, and Context caps in the outline view.
• Fixed a bug where the last 2 pixels of an item’s note summary was not faded out.
• Fixed a bug where the content placeholder background was drawn at the wrong scale.
• Reused default launch and placeholder images for Forecast mode to save approximately 8 MB of application size.

Miscellaneous

• Improved the animation sequence when choosing an item from the Settings Menu in portrait orientation on iOS 5.1.
• The appearance of the Account Info button on the Omni Sync Server setup screen is now consistent with the rest of the Sync Setup.
