OmniFocus for the Web is only an add-on service and does not work as a standalone app. Before you can log in on the web, you will need a copy of OmniFocus for Mac, iPhone, or iPad set up to sync with this account.
If you are brand new to OmniFocus, you’ll want to start with downloading native copy of OmniFocus on an Apple device, then set up syncing during the first run experience.
