Before you start the free 14-day trial—and after the trial period expires—OmniGraffle 3 will operate in a free viewer mode which allows you to use the app as a reader for OmniGraffle files. In this read-only mode, you can look at documents, interact with actions, and switch canvases. You can also use the viewer mode to export documents you’d created during the trial into the PDF and PNG image formats, or share the OmniGraffle file in its current .graffle format.
When viewing documents in this mode, you’ll see a bar at the bottom of the screen that confirms you’re using the free viewer, with an Unlock button that will take you to the In-App Purchases window should you decide to purchase OmniGraffle.
The OmniGraffle free viewer is a great way to let other users interact with and review your designs, without having to export your diagram into a different format. When you’d like to share your OmniGraffle document with another iOS user who doesn’t own OmniGraffle, let them know they can download the app for free from the App Store and use it in this viewer mode. Starting the trial is not a requirement for activating the viewer mode—all you need to do is open the app.Last Modified: Jan 29, 2020
