••• Check out Bookends - References On Tap's big brother •••

References On Tap searches PubMed, PubMed Central, Google Scholar, JSTOR, LOC, arXiv and Web Of Science to find, display, and import reference information and pdfs of the full article (if you have access privileges). You can search your personal reference library, organize your references in groups (static and smart), and email references from your device to yourself or others in a form suitable for reading or importing into desktop reference management applications. Many features are optimized for reference retrieval and management (advanced boolean searches, search for Full Text or Free Full text, recall recent searches, etc.).
Note: PubMed sometimes mistakenly lists a restricted Full Text article as Free Full Text, and References On Tap identifies them as such. In these cases, you'll need access privileges to read the Full Text.

Use iCloud to sync all your libraries and attachments across Macs and iOS devices, and have full access to your references and sources when you're on the go.

References On Tap 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. 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) is a separate in-app purchase and requires a subscription that is renewable on a yearly basis.
Subscription is for one year and can be auto-renewable. The subscription might renew if it wasn't canceled more than 24 hours before the renewal date. No cancellation of the current subscription is allowed during the active subscription period.
If the subscription is not renewed, Pro Features will be disabled.

New app loses previously paid features

I previously paid $9.99 for PubMed Tap to maximize the app’s features. With the new app, I’ve lost those features and am now relegated to ads, etc, unless I pay more. Those that paid to streamline PubMed Tap should not have to pay again.
