Is there another way of saying 'user-unfriendly'?
The direct antonym of user-friendly is user-hostile (urban dictionary), a word used frequently amongst those in the user experience fields:
- Jakob Nielsen (2)
- Alex Payne (of Twitter)
- Peter-Paul Koch (of Quirksmode)
- Russell Beattie (of Yahoo and Nokia)
A couple options:
Unintuitive
Clunky
Unwieldy implies that something is difficult to control, and can be applied to computer user-interfaces or physical devices.
A couple of other words that might be appropriate:
- Awkward
- Frustrating
If there are accessibility issues, you might call it inaccessible
