GREAT APP

This app is great for resources and to have further information!

Response from developer

We are very happy to hear you're enjoying our Prime PubMed app, especially for finding the most up-to-date information across many resources. Thank you for sharing your experience!

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.
