Great, but grapherence doesn’t work on my iOS devices anymore

I have enjoyed using Prime for at least five years now. One of its most useful options is its grapherence program. However, for the last several months to a year I have not been able to see grapherence results on either my iPhone or iPad. I don’t think it’s a specific setting, in that the problem occurred when freshly downloaded onto a new device. Have others had this problem? If so, is there a fix? It still works in my window-based PC.

Edit, 8/6/21. Hello and thank you for being a longtime customer. We are sorry to hear you're having trouble with the Grapherence feature. We've just tried reproducing the problem ourselves and have not been able to. Would you mind contacting our Support team so we may better help resolve the issue? You can reach us by phone (M-F, 9AM-5PM) at 610-627-9090, by email: , or by chat (through our website support page). Thank you!

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.

Must have app for each researcher!

In a current world of literature overload, this app is blessing. This app keeps me updated on recent articles in the field of my interests. The note taking app helps me recors my ideas for future brainstorming. One change which I would like is a go to favorite option in the app so I can glance through those articles as needed.

Developer Response ,

Thank you for your thoughtful review -- we are delighted to hear you get so much value out of Prime PubMed. There is a Favorites function available by clicking the star icon at the bottom-right corner of an article or search that you would like to return to later. Your Favorites list is accessible within the "Browse" section from the home screen.
