Keynotopia is currently offering free Keynote mockup templates for mobile, web and desktop apps. In return a predefined Twitter message (called “free with a tweet”) must be posted so for those that have yet to join in on the Twitter vibe it might be possible to alley with a friend or colleague having one of those Twitter accounts.
The templates can be downloaded here.
This quick guide provides some startup advice when first playing with the Keynotopia templates and Keynote.
I recently attended the conference MobileHCI 2012 in San Francisco and was made aware of this offer during the tutorial “Designing and deploying mobile user studies in the wild: a practical guide” organized by Karen Church.
