TS Compiler

TS Compiler puts the TypeScript compil er itself on your phone. Not a transpiler that strips the annotations and hopes — the compiler that ships on npm, bundled in the app and running in your device's own engine. Your program is type-checked against the real standard library, and only then does it run. That is what tsc does, and it is why the types here mean something. Nothing leaves the phone. No account, no upload, no waiting on a server. TYPES THAT ACTUALLY CHECK - Real diagnostics as you type: TS2322, TS2345, TS7006, with the line they are on - Interfaces, generics, unions, narrowing, keyof, conditional types - Checked against the genuine lib.es2020 declarations, not a stub - A program that does not compile does not run, and tells you why WRITE COMFORTABLY - Syntax highlighting tuned for TypeScript - Line numbers that stay correct on wrapped lines - Auto-indent, auto-closing brackets and quotes - A keyboard accessory row for the symbols a phone keyboard hides - Undo and redo that group your keystrokes sensibly - Choose your font, size, and line spacing REAL TOOLS, NOT A TOY - Format your code with one tap - Syntax trees (AST and CST) from the TypeScript parser itself - An outline of your functions, classes and interfaces - Scan printed code with the camera and turn it into text - Import and export .ts files, or open one shared from another app - Turn a snippet into a shareable, syntax-highlighted image - Save your own snippets and insert them anywhere FREE, WITH PREMIUM IF YOU WANT IT Everything above is usable for free, with a daily run allowance that resets each day. Premium removes the limit and unlocks formatting, OCR, syntax trees, import and export, extra fonts, custom snippets, and watermark-free image export. Available monthly, yearly, or as a one-time lifetime purchase. PRIVACY Your code stays on your device. We do not upload it, and we do not ask who you are.
