archive vs Vector3D

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

Vector3D: Math Plotter brings your math to life — plot vectors, points, and line segments in interactive 3D space, right on your iPad or iPhone. Whether you're a student tackling linear algebra, a teacher preparing classroom demonstrations, or a physics enthusiast exploring 3D geometry, Vector3D gives you an intuitive tool to visualise mathematical objects the way they really look. FEATURES • Plot vectors with custom start points, components, colours, and thickness • Visualise points and line segments in full 3D • Display vectors in i, j, k notation with automatic magnitude calculation • Labels follow each object in 3D space for easy identification • Adjust axis and grid size to fit any scale • Save scenes as .vviz files and reload them anytime • Share scenes via AirDrop, Files, or any app • Capture and share screenshots of your 3D scene • Dark mode and light mode support • Available in English, Traditional Chinese, and Japanese • Works completely offline — no account required, no data collected FREE vs PRO Free: Plot up to 10 objects per day, save up to 3 scenes Pro (one-time purchase): Unlimited objects and unlimited scene saves PRIVACY Vector3D collects zero data. No analytics, no ads, no tracking. Everything stays on your device. Perfect for: • High school and university students studying vectors, linear algebra, or calculus • Math and physics teachers creating visual aids • STEM learners curious about 3D geometry
