OmniFocus does not offer a standalone app for Windows, but if you are or will also be using OmniFocus on an Apple device, our OmniFocus for the Web companion services makes it possible to work with your OmniFocus data on a Windows (or Linux) PC!
If you don’t want to or can’t use OmniFocus for the Web, there are still some other things to use your Windows PC as part of your OmniFocus workflow.
Many of our Windows customers have long used our Omni Sync Server’s Mail Drop service to loop their PC into their OmniFocus workflow. By using Mail Drop, you can capture items into the OmniFocus Inbox from any device that supports email.
In addition, if you’re utilizing Outlook for Windows and it syncs with Microsoft Exchange, by configuring Exchange on your iOS device you can set up a one-way migration of Outlook Reminders into OmniFocus through our Reminders Capture feature. While this was originally designed around using Siri to dictate tasks into OmniFocus via the Apple Reminders app, this workflow offers the side benefit of allowing any program that can sync to Reminders.app a way to get tasks into OmniFocus for iOS.
