Users who currently own the iPhone-only OmniFocus 2 (legacy support edition) are able to just pay the difference in price to get the Universal app, OmniFocus 2 for iOS. This is possible by using the App Store’s new “Complete My Bundle” feature that was introduced in iOS 8. We’ve created the OmniFocus Legacy Support Bundle for the purposes of helping our existing OmniFocus 2 customers to upgrade to the Universal app.
To take advantage of this discount, log into the iTunes App Store with the same Apple ID you originally used to purchase OmniFocus 2. When viewing the OmniFocus Legacy Support Bundle, you’ll be offered a discounted price for the remaining app in the bundle (OmniFocus 2 for iOS). For example, in the U.S. Store the price of OmniFocus 2 for iOS should appear as $20.00 Buy Bundle if your previous purchase is recognized.
