About this app

Java/Kotlin IDE turns your phone or tablet into a real Java and Kotlin development environment with a genuine Linux terminal — write, build, run, and debug code anywhere, no desktop required. Built for students, backend engineers, and Android developers who need real tools, not toy simulators.

REAL LINUX TERMINAL
A real, full Linux command line. Run java, javac, kotlinc, mvn, and any Linux command directly, install packages, and manage multiple terminal tabs with quick-key bars for symbols that are hard to type on mobile keyboards.

PROPER JAVA/KOTLIN TOOLCHAIN
Full Maven project support, set up automatically when you create a project, with syntax-aware editing, live error checking, and code navigation built right in.

POWERFUL CODE EDITOR
Fast, accurate syntax highlighting for Java, Kotlin, and 15+ other languages. Includes find & replace, go-to-line, fuzzy quick file search, a built-in hex viewer, a clean diff viewer, and 10 bundled programmer fonts including Hack Nerd Font, JetBrains Mono, and dyslexia-friendly options.

BUILD ANY PROJECT, ANY LANGUAGE
Create new projects from ready-made templates that set up the right tools automatically — projects stay 100% standard and usable outside the app. Beyond Java/Kotlin, Java IDE also supports:
• Java & Kotlin frameworks: Spring Boot, Quarkus, Ktor
• Python (FastAPI, Django, Flask), Go (Gin, Fiber, Echo), Rust (Axum, Actix, Rocket)
• JavaScript/TypeScript (React, Next.js, Vue, Nuxt, Svelte, Astro, Express)
• PHP (Laravel, Symfony), Ruby (Rails, Sinatra), C/C++ (CMake)
• Swift, Bash, Lua, Perl, R, Zig, Lisp, Dart

RUN & PREVIEW LIVE
Build and run your programs straight from the toolbar, with terminal output streamed live. For web apps and APIs, your app opens automatically in a built-in browser preview without leaving the IDE.

BUILT-IN BROWSER INSPECTOR
For web projects and APIs, inspect running apps like a desktop browser: view page elements, styles, debug scripts, monitor network requests, check storage, and audit accessibility — all in one place.

FULL GIT CLIENT
Stage and commit changes, create/checkout/merge/rebase branches, manage stashes, browse commit history, resolve merge conflicts with a visual diff resolver, and manage remotes. Connect securely to GitHub, GitLab, and Gitea/Forgejo, and clone any repo in one tap.

SMART FILE MANAGER
Browse, create, rename, move, compress, and share files and folders through an intuitive, fast file tree built for touchscreens.

SPLIT-SCREEN, MULTI-TAB LAYOUT
Arrange code, terminal, and preview side by side with split-screen panes and a flexible tab system built for both phones and larger screens.

PRODUCTIVITY TOOLS
Project-wide search & replace with regex support, a fast command palette for quick actions, and a reusable code snippets manager with per-language snippet bars.

FULLY CUSTOMIZABLE
~20 built-in app themes (VSCode, Dracula, Nord, Tokyo Night, JetBrains, and more), terminal color schemes, and custom coding fonts. A one-tap Reset Environment restores a clean workspace whenever you need a fresh start.

SECURE BY DESIGN
Credentials and tokens are protected with encrypted storage, keeping your GitHub, GitLab, and Gitea logins safe on-device.
