Open Access Helper will identify > 23 million free scholarly articles from over 50,000 publishers and repositories to help you overcome the paywall imposed by many scholarly publishers, right from your iPhone or iPad. Each Open Access found within the app is a legal and trustworthy copy. Privacy and transperency is important to me, so please read on to learn more.

You'll get the most out of this app, if you use the iOS Share Sheet!

The app identifies the DOI (Digital Object Identifier) of an article and queries API for a legal Open Access copy, based on the identified DOI. If one is found, you will get a clear indication, including a preview of the URL where the Open Access is found.

Highlight text on a page and use "share" to send your selected text to - the worldwide largest Open Access Aggregator. If your text contains a DOI, the app will query again.

The app itself, will allow you to query, see results and access Open Access version of documents.


I, as the developer of the app, get none of your data. All the app logic happens within your device. Subsequently, I have no metrics to help app development and thus rely on your direct feedback. As I have no metrics, I also have nothing to sell - to me this is a clear privacy win!

You don't need to trust my word for this privacy promise. The code for the app is on GitHub and I invite you to check it out. Visit the Website / Support links to access the app homepage and navigate from there to the Github repository.

If you wonder, how I make money on this, there is an easy answer: I don't. This is my hobby and I am really enjoying it! I am learning a lot with every new version, so that's my reward and if you were to drop me an eMail with a suggestion or two, that would also count as a reward...

ACKNOWLEDGMENTS I would like to thank the providers of and for providing an awesome service to the scientific community worldwide.


Version 1.1

For this version, I focused on improving the user experience:
* in the result overview you will now see up to two lines of the title and three lines of the abstract
* furthermore in the result list an icon indicates whether a PDF is readily available (green) or a click to is needed (blue)
* in the individual result view you will now see a much improved display, including navigation at the bottom that lets you navigate from one record to the next and access full-text / record even with long abstracts. The goal was that these buttons are easy to reach on iPhone and not distracting on iPad

In the Action / Search Extension, I focused on:
* bringing support for PubMed and IEEE, helping identify DOIs there
* fixed a bug, which occurred when a page included an invalid DOI
* improve the flow for "highlight & search" actions, which will now take you to the search app, instead of initiating a web search

Lastly, I resolved a number of smaller bugs and ensured more comprehensive localisation in both English & German.
