How is Mendeley on iPad? I use it a lot on my MacBook, so I wonder if the experience is as good on an iPad. Can you use Apple Pencil with it?
Mendeley = Elsevier = Evil incarnate. If you care about universities and their libraries you cannot support Elsevier.
Their iPad app is pathetic anyway. No freehand annotation support, your notes are trapped in Elsevier's evil servers forever. There used to be a third party app called Papership to do freehand annotation, but it's been discontinued.
I have been using Papers for the last 5 years. Started with version 2 but switched to version 3 as soon as it became public. It allows you to search, organize, read and annotate in the same app. It sorks well together with Scrivener for writing and the developers even helped us users in writing our own Apple scripts to get the most from the app.
Rumor has it that they will change to a subscription model and if they do I will probably switch to Bookends.
Papers3 on mac and iPad since five years
So far very satisfied
However I am consern about updates as the have been problematic before
Papers is currently the most capable app. And it's a little less evil than Mendeley. But only just. poster above is right that updates have been troublesome since v.1. But the original developers have all fled the company following acquisitions. This may mean that the original beauty of Papers might be lost, but also hopefully their original incompetence when it came to updates.
Papers is in the process of merging with ReadCube, which has a terrible Java style pathetic app on the Mac and no real iPad support worth mentioning. This is potentially a disastrous move, and they are running 6+ months behind schedule with the beta program, which doesn't bode well...
Zotero on my Mac. I use the PaperShip app on iOS. I do pay $120 a year for unlimited space because I sync everything. So my highlighted docs are on every device. I highly highly recommend: so much so, that, as a broke graduate student, I am more than willing to pay the $120 per year.
Zotero is of course the ethical choice. But they have no iPad app. PaperShip has been discontinued. I truly wish there was a workable iPad client for Zotero.
--> conclusion: it's a terrible scene. I think about this *a lot*, and my 3000+ pdf and academic book library has never fully recovered since the death of Sente (which used to be the best reference manager for Apple's ecosystem) a few years ago. At present I use Papers but it's a very very shaky platform.
