You will take advantage of the iPad and iPhone Retina screens and never need to print your publications anymore.

ANNOTATE | PaperShip provides a lot of annotation types which go far beyond what most of the reference managers offer (available through In-App Purchase). And as our tools are compliant with the PDF standard, your annotations will be available in most of the other readers.

METADATA | PaperShip allows you to read and edit article's metadata. You can now add tags, update title or change authors in an easy way whatever the type of document you are reading.

IMPACT | PaperShip is the first reference manager to link your articles to the new almetric data! Just know in real time what are the impacts of your publications inside the scientific community.

MANAGE | PaperShip keeps your articles organized based on your Mendeley/Zotero folders. Add a paper to your favorites or move it to another folder by using an incredible pane and swipe navigation. Your articles will always stay at your fingertips with the search engine.

IMPORT | Just import a new paper by tapping some keywords or looking at author name and PaperShip will bring it to your library. By selecting the Open Access option, you will be able to download automatically the linked PDF for free.

SYNC | Always stay up to date between your mobile library and your desktop application. Once you add or annotate a PDF, it will wirelessly be saved on the Mendeley/Zotero platform to be available on all of your devices.

SHARE | You have found a new incredible article? Just share it with colleagues in your groups, by email or on social networks like Twitter and Facebook and bring reference managers to the science 2.0 step.

Excellent .. but much under the hood and no manual

I’m delighted to see a recent update to this app, as it indicates it has not been abandoned. As a research oriented medical director I spent a good deal of my time reading scientific PDFs and annotating these for future reference or citation. Although this is not the most intuitive program to set up, it does synch beautifully with Zotero and is an excellent annotation app. Moreover, one can easily export annotations by using the share icon (box with upfacing arrow) and using email command. This appears to be an undocumented feature - and I have no idea why it works this way-but it does so beautifully. Would greatly benefit from some instructional videos as many features hidden, and again not intuitive. Due to Zotero synch has largely replaced most of PDF readers, e.g. Goodreader. Once you have figured out the kinks and qwerks your efforts will be well rewarded. By all means also implement Zotfile on Zotero.

Annotations Pack does not work (Jan 2022)

Apple should not let people pay for the in-app features because they DO NOT WORK. The app itself seems well-designed and intuitive. You can sync it with your Zotero library to view any PDF you have in Zotero. But to do any kind of markup on the PDFs, you have to pay for the Annotations pack. The app lets you preview the functionality of the paid features but it’s not a true trial — you get to play around annotating a sample PDF within the app but can’t test syncing the annotations with your own Zotero account. I liked the features (and didn’t see the purpose of a read-only PDF viewer that synced with Zotero) so I paid for the Annotations pack right away. The annotations I made to PDFs within the Papership app never showed up in Zotero. It just never worked at all. It was supposed to be automatic and seamless. But it doesn’t work and there is zero support from the developer. I later found lots of similar complaints going back several years on forums. I can’t believe Apple still lets this app sell features that are completely nonfunctional. Save yourself the headache and $10 by using the Zotfile plugin and a PDF reader of your choice until Zotero finally releases its iOS app.

Great, but please fix the annotations

I’m not an academic researcher, but I do research and write on some esoteric subjects, so I was looking for a god way to collect and work with references. I found Zotelo and PaperShip and they’re nearly perfect. I use the Zotelo browser plugin and ISBN search to record references, and PaperShip allows me to reference them anywhere and make notes. So far it works wonderfully.

The only problem is that I’d like to purchase the PDF annotation feature so I don’t have to use an external app, but looking at reviews here and elsewhere it appears to be broken. The rest of the app is great, and I’d like to support the developer, but not if it didn’t work.

Fingers crossed this will be figured out soon!
