2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.
What its author says it does
Copied from the file, not written here
Mobile app debugging for iOS, Android, cross-platform frameworks. Use for crashes, memory leaks, performance issues, network problems, or encountering Xcode instruments, Android Profiler, React Native debugger, native bridge errors.

Mobile App Debugging
Debug mobile applications across iOS, Android, and cross-platform frameworks.
iOS Debugging (Xcode)
// Breakpoint with condition
// Right-click breakpoint > Edit > Condition: userId == "123"
// LLDB commands
po variable // Print object
p expression // Evaluate expression
bt // Backtrace
Memory Debugging
- Use Memory Graph Debugger to find retain cycles
- Enable Zombie Objects for use-after-free bugs
- Profile with Instruments > Leaks
Android Debugging (Android Studio)
// Logcat filtering
Log.d("TAG", "Debug message")
Log.e("TAG", "Error", exception)
// Filter: tag:MyApp level:error
Common Issues
- ANR: Check main thread blocking
- OOM: Profile with Memory Profiler
- Layout issues: Use Layout Inspector
React Native
// Remote debugging
// Shake device > Debug JS Remotely
// Console logging
console.log('Debug:', variable);
console.warn('Warning');
console.error('Error');
// Performance Monitor
// Shake > Show Perf Monitor
// Target: 60 FPS, <16ms per frame
Network Debugging
// Intercept requests
XMLHttpRequest.prototype._send = XMLHttpRequest.prototype.send;
XMLHttpRequest.prototype.send = function() {
console.log('Request:', this._url);
this._send.apply(this, arguments);
};
Debug Checklist
- Test on physical devices (not just simulators)
- Test on older device models
- Simulate slow 3G network
- Test offline mode
- Check memory under load
- Test rotation and safe areas
- Verify 60 FPS target
Performance Targets
| Metric | Target |
|---|---|
| Frame rate | 60 FPS (16ms/frame) |
| Memory | <100MB |
| App launch | <2 seconds |
