Apple Invites is a simple new app, so much so that I'm surprised it hasn't been around longer. It's designed to help you create an invitation and invite your friends, family or colleagues with minimal fuss. You can drop in the image and event details and then share with a simple iCloud link, or invite individually if you prefer.
Invites has just appeared on the app store here in the UK but you can also access it directly in your iCloud. That means that even though this is an iPhone only app right now, you can work on your invites on a desktop too.
