Helping me keep up with the literature

I am absolutely loving this app. It is exactly what I need for keeping updated with publications in my field of interest. I like the push notifications to let me know of new additions to my searches. One improvement I'd make is the ability to delete irrelevant stuff from my lists (perhaps another option when you slide to tag an article). I recommend this to anyone who regularly uses pubmed. Even allows you to log in to academic libraries (if you are registered users) to get full texts. Much better than the readcube app.

Best App On My Phone

Kind of like having the Library of Alexandria (of health) available at the touch of a fingertip on your phone. I spent years searching pubmed… but this app has made my amateur health fact-finding adventures more enjoyable, productive, and fast. I can go and do things in four or five or six other apps, and then come back to this app, and it still is in the exact same place where I left it, whether a search, a paper pdf, or whatever. My Apple iPhone Podcast App doesn’t even do that! A+

Great research tool!

I have enjoyed using Prime for at least seven years now. One of its most useful options is its grapherence program. It allows me to look at the abstracts of articles upon which the title I am reading are based AND any articles that have subsequently referred referred to that same title. I can also get some idea as to the influence of a given reference by the number of articles that refer back to it.
