It's arXiv preprint search & PDF viewer app. All features are completely free to use. arXiv.org e-Print archive https://arxiv.org/ URL scheme: preprint:// Note: - This app uses arXiv APIs. - This app is run by an individual and has nothing to do with arXiv. Thank you to arXiv for use of its open access interoperability. --- * arXiv arXiv (pronounced "archive"—the X represents the Greek letter chi [χ]) is an open-access repository of electronic preprints and postprints (known as e-prints) approved for posting after moderation, but not peer review. It consists of scientific papers in the fields of mathematics, physics, astronomy, electrical engineering, computer science, quantitative biology, statistics, mathematical finance and economics, which can be accessed online. In many fields of mathematics and physics, almost all scientific papers are self-archived on the arXiv repository before publication in a peer-reviewed journal. Some publishers also grant permission for authors to archive the peer-reviewed postprint. Begun on August 14, 1991, arXiv.org passed the half-million-article milestone on October 3, 2008, and had hit a million by the end of 2014. As of April 2021, the submission rate is about 16,000 articles per month. Quoted from: https://en.wikipedia.org/wiki/ArXiv

Verdict
The clearest difference is review sentiment: archive at 100% against O'Reilly's 46%. archive also leads on monetization model (ad-supported vs subscription) and rating (5.0 vs 4.7). O'Reilly's advantage is ads (none vs shown) and ratings volume (34K vs 2). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
archive holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: O'Reilly has 34K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 46% of O'Reilly's written reviews are positive against 100% of archive's.
O'Reilly ships an update fortnightly, archive every 2 months. The most recent releases landed on October 24, 2026 and October 7, 2026 respectively.
