Bookends is a reference management app for your iPad, iPhone, and iPod touch. You can search Amazon, arXiv, Google Books, Google Scholar, JSTOR, the Library of Congress, PubMed, PubMed Central, and Web of Science (requires access privileges and ip authentication) for references and download them, with pdfs (requires access privileges), to your personal library. Use the built-in browser to access Web sites (EZProxy compliant). Organize your references by groups (static and smart), annotate your pdfs directly within Bookends, and email references from your device to yourself or others in a form suitable for reading or importing into reference management applications. Autofill references from the internet by DOI or ISBN. Scan barcodes.
Use iCloud to sync all your libraries and attachments across iOS devices and with Bookends running on the Mac, and have full access to your references and sources whether you're at your desk or on the go.
Bookends for iOS without a Standard Version in-app purchase is limited in the following ways: searches return a maximum of 20 references, only 50 references can be stored in your local database, PDFs that you annotate on the iOS device are watermarked, and ads are shown. To have full access without these restrictions you must make a purchase from within the app ("in-app purchase”).
Pro Features Yearly Subscription (cloud sync of references and attachments, multi-library support, unlimited barcode scans) is a separate in-app purchase ($9.99) and requires a susbcription that is renewable on a yearly basis.
Subscription is for one year and can be auto-renewable. The subscription can be managed in iOS -> Settings > iTunes & App Store > Subscriptions. The subscription might renew if it wasn't canceled more than 24 hours before the renewal date.
If the subscription is not renewed, Pro Features will be disabled.
No cancellation of the current subscription is allowed during the active subscription period.
Standard Version - $9.99

Ratings and Reviews
Best reference manager in my opinion
If you use Mac and iOS, I think this app is worth looking at. It works very well for me. The main advantage of Bookends over other apps like Papers or the seemingly abandonware Sente is that Bookends saves your PDF annotations like highlights and notes in the actual PDF. This means that if someday, you decide to stop using Bookends, you can take all of you PDFs to some other system/app and all of you annotations like highlights and notes will come with you because they exist in the actual PDFs. With Papers, Mendeley, Sente, and all other apps I have tried, the annotations are not actually stored in the PDF but in a app specific database and cannot be easily bulk exported. Good luck transferring from Papers to some other app and realizing that none of your highlights come along unless you individually export every single one of your possibly thousands of articles.
Another great advantage of Bookends is its iCloud sync of the files. It all just works.
iCloud Sync does not handle attachments
Looked promising but is lacking in proper sync functionality. I set up the first library of 3 citations and saved to iCloud (purchased all upgrades) using an iPad. Down-synced on iPhone. There are seemingly no attachments. Re-downloaded one from the web and now there are suddenly two attachments. The others have again no attachments. Already read all available documentation and web posts without success and double-checked program, sync and iCloud settings. Seems to be a bug, but one that wasted my $20 expenditure. I retracted my one star rating but needs a try-before-you-buy for its advanced features for any unreserved recommendation and before the prospective user would spend money without any refund option. Also, the interface does not reflect the purchase and subscription status as the purchase/upgrade options appear unchanged irrespective of purchase status.
I appreciate the developer response and had already tried those options and read all documentation. Repeating the steps did not work unfortunately.
Developer Response ,
Note: for those who are reading this message, we have a forum on our web site and a support email link in the Bookends About section. These are the preferred ways of reporting bugs or sending feature requests.
So far quite promising!
After a bit of difficulty getting the sync set up, I was able to get this set up, and so far it's worked remarkably well. Be aware that there are sample libraries when you bout to the program, so you may inadvertently add some of those references to your program. I've tried several similar programs and always lost annotations in the sync process (papers 3, mendeley) or had other problems (sente). It's been about a month since I started using this, and so far the sync had been seamless. The program itself is quick and intuitive once set up. I also very much appreciate the responsiveness of the developers to questions and problems. I would highly recommend this program. Definitely worth the small annual free to have the piece of mind.
