Helping me keep up with the literature

Grumpy Scottie

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.

Thanks for using Prime and for your review! We are continually looking to add useful features to our application. Customer feedback such as this is critical to helping us improve our product.

Cannot save, print nor share articles.


This app is good for searching for articles. But it is worse than using Safari since you cannot save, print nor share the articles you found. The information is stuck in this app. You can't save it for reading on a Mac or other device. For this egregious deficiency, this app only deserves 2 stars. It is less useful than searching on medline in Safari.

Developer Response

Thank you for your feedback. Users may share and save articles multiple ways and in multiple formats. They can be shared via email, Dropbox, Facebook, and Twitter. By Email and Dropbox you can save it in ABSTRACT (text), MEDLINE (for EndNote, etc.), XML, HTML, or ASN.1. In addition, there are features that can only be found in the Unbound Prime app, including Grapherence (a visual search feature for related content), a ForYou feature that finds articles of interest based on your use of the application, and a Journal Browser feature. We hope you find these features useful.

Great app


It is a good app and easy to use. Saving articles and searches can be a little frustrating if you haven't used the app before. It is simplistic and covers a lot of journals, some free and some you have to pay for, just like any other sources.

Developer Response

Thank you for your feedback. We encourage you to continue to explore unique features like "For You", "Grapherence", and our journal tracking feature.
