The best way to search, organize, and share PubMed® literature directly on your mobile device

Unbound MEDLINE has been completely redesigned and rebranded to become Prime PubMed. This redesign includes an all new look, enhanced search functionality, ability to organize your research, and alerts when new articles of interest to you are published.




The new free Prime PubMed app connects you to the most up-to-date journal citations and abstracts from the complete PubMed database. In addition to the ability to perform powerful searches and link to the publisher’s full text articles, Prime also provides a number of exclusive tools not available anywhere else creating a one-of-a-kind user experience.


  • Search: Perform evidence-based searches by keyword, author, or journal then link to full text articles.
  • Organize: Bookmark and Tag important articles and searches to quickly return to them later
  • Share: Share articles directly from the app via Email, Twitter, Facebook, SMS, Dropbox, and more
  • Grapherence®: Unbound’s unique search option allows you to visually explore the influence and interrelationships among journal articles
  • For You: Discover new articles in a feed designed specifically for you based on how you use the app
  • Browse: Select specific journals you want to follow and receive alerts when new articles are published

Grapherence® is Unbound’s interactive search that graphically represents the influence and interrelationships among journal articles. Tap the Grapherence button within a citation and instantly see how that article is related to others. Using this exclusive feature the researcher quickly uncovers difficult to find entries, determines overall significance, identifies clusters of thought, and locates seminal articles.
