Great sort features but it’s not free like PubMed
So this app is really cool in that it sorts by levels of graded evidence, impact factor, relevance — all of the quality studies. However, the search screen is misleading and a bit of a false advertisement. Under the cloak of searching PubMed (and it appears to actually BE PubMed), you get one search but then must subscribe. $50/per year. So the real value is the sorting features but it also delivers full text when ALREaDY FREE in PubMed Central.
