Fellow grad students: download this immediately! Zotero is absolutely indispensable if you need to read and keep track of scientific publications. Any paper you can find a DOI for you can automatically import (often along with a PDF) which you can then open, read, and annotate from within the app. The app automatically syncs across devices and integrates with MS Word, making adding citations a breeze. Zotero has transformed my research for the better — I just wish I'd started using it sooner!

Very useful for helping me organize & annotate papers & reports for research. However, it often glitches when I try to add webpages, loading forever but often never adding them. It's worse if I need to add a PDF directly. I usually have to download a copy or add it to my Google Drive & then manually add it. The cost of extra storage is also insanely high (e.g. $20 for 2 GB & $60 for 6 GB). For comparison, 2 Terabytes from Google is $99 per year. Really hoping to see better storage prices soon!

If you’re having trouble sharing to the app, please post to the Zotero Forums so we can investigate. We’re not able to troubleshoot problems via the Play Store. Also note that we provide unlimited storage for $120/year, which is comparable to pricing plans from large companies like Dropbox, Box, etc.

simple and great app for reading and notetaking on pdfs. missing: highlighter/semi transparent brush so you can highlight areas that are not necessarily text (i have a "photo pdf" now that is not possible to highlight properly)
