TraceLens: Source Code Viewer

[ TraceLens - Mobile Source Code Browser & Viewer ]

In the age of AI, reading and understanding code is more important than ever. Build a daily habit of code reading with TraceLens!

TraceLens is a powerful mobile code browser and source code viewer that allows you to lightly and quickly analyze large-scale C/C++, Java, Python, Kotlin, Go, Rust, JavaScript, and TypeScript projects right on your Android device.

By guaranteeing 100% local, offline analysis without transmitting any code to external servers, you can safely browse core enterprise security codes or personal projects without worrying about data leaks.

🛠️ Detailed Features

1. Smart Code Navigation & Symbol Analysis
• Project Symbol Search: Blazing fast search for definitions of classes, functions, variables, etc. across the entire project.
• Go to Definition & Find References: Tap a specific symbol in the code to instantly jump to its definition, or find and show all references where the symbol is used throughout the project.
• Function Outline: Extracts and displays a list of functions per file. Use the filter to instantly navigate to the desired function, even in massive codebases.
• Header File Jump: Quickly jump between related header (.h) and source (.cpp) files in C/C++.

2. Powerful Code Viewer & Editor-Level Convenience
• Quick Open: Instantly find and open desired source files by typing just a part of the filename or path within the project.
• In-file Search: Search for keywords within the currently open file and conveniently move to the previous/next matching positions.
• Bookmarks & Recents: Tap a line number to easily toggle a bookmark, and quickly pull up the list of files you recently analyzed.
• Go to Line: Enter a line number to instantly jump to a specific line, even in files with tens of thousands of lines of code.

3. Customizable Viewer Experience
• Syntax Highlighting Themes: Supports developer-friendly themes like VS Code Dark, GitHub Light, and Monokai to reduce eye strain during extended code reading.
• Font Size Adjustment: Dynamically adjust the text size (sp scale) to suit your eyesight in real-time.
• Tab Width: Configure tab spacing (number of spaces) to match your project's coding style.

4. 100% Strict Local Offline Security
• Never uploads your device's source code to external clouds or servers. It builds its own indexing database solely through a high-performance local parser built into the device.

5. Reasonable Usage Model
• Enjoy all premium features without restrictions for 6 hours simply by watching a short rewarded ad.

👨‍💻 Highly Recommended For:

• Developers who urgently need to review or check code while commuting or on the go.
• Engineers working in secure offline environments without internet access where code must be kept local.
• Anyone wanting to easily grasp the overall structure of C/C++, Java, Python, Kotlin, Go, Rust, and JS/TS projects via a mobile device.
• Students and programmers who need a lightweight, fast, mobile-optimized source code viewer instead of a heavy IDE.
