Store description excerpt
Aperio is a code reader for iPhone and iPad. Not an editor — a reader. It is built for the times you want to actually read source code on your phone: reviewing a pull request on the train, checking how a library works, or reading a file someone just sent you. Open code from anywhere • Share a file or a GitHub link to Aperio from any app • Open files from the Files app, iCloud Drive, or another app's "Open In" • Paste a snippet straight from the clipboard • Load a URL from GitHub, Gist, or GitLab — Aperio finds the raw file for you Built to be read Syntax highlighting for more than 40 languages, with themes designed for long reading sessions. Adjust the font size by pinching, turn line numbers and word wrap on or off, and pick a theme that suits the light you are in. Understand the structure, not just the text Aperio parses your code with tree-sitter, the same engine used by modern editors, so it understands the shape of a file: • Sticky scope headers pin the enclosing type and function to the top of the screen, so you always know where you are • A symbol outline lists every class, struct, function, and property — tap one to jump straight to it • Bookmarks save the lines you want to come back to • Search jumps between matches with a running count Yours, and private Aperio has no accounts, no analytics, and no tracking. Files you open stay on your device. The app talks to the network only when you ask it to open a URL, and then only to the address you gave it. Aperio Pro Aperio is free to use, including bookmarks, the symbol outline, sticky headers, and five URL loads a month. A single one-time purchase — no subscription — unlocks: • Focus Mode, which dims everything outside the block you are reading • Unlimited URL loading • Offline caching of URL-loaded files • Unlimited bookmarks per file • Your full recents history • Six additional themes, including a true-black OLED theme Languages Swift, Python, JavaScript, TypeScript, JSON, YAML, HTML, CSS, Rust, Go, Java, C, C++, Ruby, Bash, Kotlin, Dart, PHP, Scala, Haskell, Elixir, Lua, R, SQL, Dockerfile, TOML, Terraform, Zig, Objective-C, C#, Perl, OCaml, Clojure, Erlang, Julia, Groovy, PowerShell, Nix, Markdown, LaTeX, Protobuf, GraphQL, and more.
