Office Mobile is free to use for viewing and editing (basic features) existing documents, saving to the cloud. The paid Office 365 subscription is only required to create new documents and unlock the full functionality. Your average user can get by on the free version. Office 365 is aimed towards students, small businesses and cloud-friendly enterprise environments.
Just to confirm what fatclue said above, your information here is outdated. Office on iOS & Android is now in fact free and fully functional without Office 365. I use the Android tablet version which just updated from Preview to whatever you call the normal mainstream version. It's a brilliant piece of work!
