To access Clipparoo on any mobile device, just go to www.clipparoo.com. Clipparoo will recognize most mobile devices and tablets as mobile devices and send you to the mobile Clipparoo site, where you can view your Clippboards, Clipps and Brandboards, create new content, and more. (On some tablets, you'll just be sent directly to the full Clipparoo.)
On the iPad you'll go to the regular, full sized Clipparoo page. Everything on the page will appear in two columns on the iPad, no matter what you've selected as your default. On the iPhone, you'll be automatically redirected to a mobile version of the site.
If you are on the mobile version of Clipparoo and want to see the full site at any time, just click the three bars icon in the upper right corner of the page, and select "Use Desktop Version." (The next time you go Clipparoo on your device, you'll be returned to the mobile site.)
