Rust Starter
Learn and practice Rust locally
Write, compile and run Rust 2024 standard-library console programs on iPhone, iPad and Mac. Includes 20 free basic lessons, API reference, practical guides, Explore articles and on-device search.
Projects and IDE Pro
The free version includes one editable default workspace. IDE Pro is an optional one-time, non-consumable purchase for multiple local projects and project duplication. Renaming and backing up the default workspace do not require IDE Pro. The default workspace remains protected from deletion for all users. Courses and exercises remain free.
Runtime scope
Uses a bundled community rustc 1.96.0-dev / Cranelift toolchain, not an official stable Rust distribution. Supports the standard library within a WASI environment and multi-file mod projects. Cargo, third-party crates, native libraries, networking and threads are not supported. Set standard input before running; interactive input during execution is not supported.
Local data
Code is compiled and run on the device. Projects and learning progress are not uploaded to developer servers. There is no app account, app-provided cloud sync or backup. Keep a separate backup of important work.
