7,000+ code examples in 20 languages. Tap Run and see the real output right in the app. Ready-made code for everyday tasks in Swift, Python, C, C++, Java, C#, JavaScript, R, Rust, Golang, Delphi, PHP, Ruby, Objective-C, Kotlin, Lua, TypeScript, Clojure, Bash and SQL. One purchase, yours for good: no subscription, no ads, no in-app purchases. Up to 80 runs a day. • 1,100+ topics, including strings, collections, files, networking, concurrency, regular expressions and design patterns. • What changed in each version: over 1,000 new features across 175 language versions, with before-and-after code. • Keyword and function reference for every language: over 4,200 articles. Browse, search, or tap a word in the code to open its article. • SQL: 200+ queries (JOIN, GROUP BY, subqueries, data types); more than half run on a real practice database. • Built-in Playground runs over 85% of examples. Requires an internet connection. • Search covers the code itself, not just titles: type a fragment you remember and find the example. • Edit examples or add your own; changes are saved in the app. • Everything except running code works offline: examples, reference, search, favorites. • Easy on the eyes: light and dark themes, your choice of font and size, line numbers, and long lines that wrap instead of spilling off the screen. Examples are curated from professional sources: the code works and is easy to follow. Built by a developer for developers. Maintained since 2015.
