OmniKeyMaster is a simple app that finds App Store copies of Omni apps installed on your Mac, then generates equivalent licenses from our store - for free. This gives Mac App Store customers access to discounted pricing when upgrading from the Standard edition to Professional, or when upgrading from one major version to the next.Though the apps allow users to access upgrade pricing in the Omni store, it does not provide them with App Store versions of upgraded apps.
Another benefit: since they don't have to wait in an approval queue, our direct releases sometimes get earlier access to new features and bug fixes. OmniKeyMaster lets App Store customers access those builds, as well.
The Omni Group produces Mac apps like OmniFocus, OmniGraffle, OmniOutliner, and OmniPlan, among others.
OmniKeyMaster can be downloaded at no cost from the Omni website.
