There are several mobile apps for use with the Zotero bibliography manager.  Zotero allows you to store citation information for papers (and even PDF's of the actual papers) and access the information from any device (cell phone, tablet, computer) that you might be using.  

On the Android side, check out [Zandy][1].  On the IOS side, check out [Zotpad][2].
