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.

Excellent access & information

I have been using this going on 2 years, and it has helped me immensely. My Shih Tzu is 13 & has Cushing’s Disease, with a tumor on his left adrenal gland. The articles that I can access on here have shown me ways to blend traditional medicine with Chinese medicines, homeopathic, and other alternative medicine. I don’t know how I could have done this research without this site!!

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.
