Learn anything, offline — on your iPad or iPhone. Starting with code. KaView's vision is a universal library you learn from offline. Today it teaches you to program from real projects: structured courses, hands-on practice in a real codebase, and an AI tutor that explains any line. It opens with Mastering Believe — Kalira's free reference curriculum (MIT-licensed): markdown lessons paired with runnable code, on agents, neural networks, algorithms, system design, and the craft of learning. Or open any GitHub project and study it like a book. No autoplay. No ads. No algorithm pulling you elsewhere. Just a real codebase and the quiet tools to understand it. LEARN, YOUR WAY, OFFLINE • Mastering Believe ships with the app, and five curated collections are ready on first launch — gentle starter paths, fully yours to edit: - First steps in Python - Understanding AI agents - Build an LLM from scratch - A tour of Swift - Essential algorithms • A dedicated Cours tab: one tap downloads a course to read • Go further: a marketplace of public repos by theme — AI, Python, Swift, web, books AN AI TUTOR THAT READS THE PAGE • Ask in plain words — "explain this like I'm new," "what does this term mean," "why is it written this way" • Tap any snippet for Explain, Complete, or Refactor • On-device when Apple Intelligence is on (iOS 26+): private, no connection needed • Or bring your own OpenAI or Anthropic key READ CODE LIKE A BOOK • Markdown and source side by side, syntax-highlighted • Progress is local to the module or folder you are in — n of total for that chapter, not hundreds of pages across a whole repo • Book-style chrome: aligned prev/next arrows, ⋯ menu beside next, large tap targets • Navigate sheet puts lessons first; exercises are listed separately • Changing chapter scrolls you back to the top • Dozens of languages, rendered cleanly PRACTICE IN A REAL EDITOR • Fix a typo, jot a note, save a TODO as you learn • Sign in with GitHub, clone, edit, commit, push — without leaving the app • Token stays in the iOS Keychain BUILT FOR iPHONE AND iPAD • Native iOS 26 design: Files, Page, Cours, Chat • iPad: three-column layout, Split View, Stage Manager • Dynamic Type, VoiceOver, hardware keyboards, VS Code–style shortcuts PRIVACY BY DESIGN • No analytics, no trackers, no ads, no telemetry, no account • Data Not Collected KaView is a place to learn — a reader, a light editor, and an AI tutor, not an IDE. It doesn't run code. iOS 18 minimum; the on-device tutor needs iOS 26+ with Apple Intelligence. Open a course. Ask a question. Understand the code.

About

Codex Live Bar

Features
Read full description

Keep Codex limits visible while you work. Codex Live Bar shows session, weekly, and model-specific usage in a focused Live Activity on the Lock Screen and Dynamic Island. Create two private Shortcuts automations and the Live Activity can appear when ChatGPT opens and disappear when it closes. Refresh from the app, Shortcuts, or the Live Activity itself. Everything runs on your device. Authentication tokens stay in the iOS Keychain, usage is fetched directly from OpenAI, and there are no analytics, ads, tracking, accounts, or developer servers. Codex Live Bar is an independent client and is not affiliated with or endorsed by OpenAI. The app relies on an undocumented OpenAI endpoint that may change.
