About this app

Log Analyzer Pro is a fast, offline Log Viewer and crash diagnostics tool built for Android developers, DevOps engineers, QA testers, and sysadmins. Inspect, filter, compare, and analyze dense log files directly on your phone or tablet.

Whether you need to read Android Logcat dumps, inspect Nginx/Apache web server logs, analyze Docker/Kubernetes cloud traces, or debug JSON payloads, Log Analyzer Pro turns raw logs into structured, actionable insights instantly.

Key Highlights for Developers:

• 🛡️ PII Data Redactor & Privacy Shield: Automatically detect and mask sensitive IP addresses, emails, Bearer/JWT auth tokens, passwords, and API keys before exporting or sharing logs.
• 🔍 Fast Log Viewer & Heuristic Engine: Open massive log files smoothly with instant color-coded Log Levels (Verbose, Debug, Info, Warning, Error, Fatal).
• ⚖️ Dual-Log Diff & Comparison: Compare two log files side-by-side to catch regressions, missing events, and new crash spikes between app releases or builds.
• ⚡ 1-Tap Crash Jump: Instantly jump to the first fatal crash or exception stack trace without manual scrolling.
• 📊 Visual Analytics Dashboard: Graphically inspect error frequency, top crashing tags, and system health scores.
• 📁 Multi-Domain Log Parser:
- Mobile: Android Logcat, iOS Syslog, Flutter/React Native stack traces.
- Backend: Java, Kotlin, Python, Node.js, Go, Rust, and Ruby logs.
- Servers & APIs: Nginx, Apache, FastAPI, Express access logs, and JSON payloads.
- Cloud & DevOps: Docker container logs, Kubernetes pods, and AWS/GCP event streams.
• 🎯 Advanced Search & Regex: Filter logs by Tag, PID, TID, or complex Regular Expressions in real-time.
• 🔒 100% Offline & Private: No logs or credentials ever leave your device. All parsing and analysis run locally.
• 💾 Clean Export & Bookmarks: Star critical incident lines and export formatted reports in TXT, CSV, JSON, or Markdown.

Supported Formats:
.log, .txt, .csv, .json, Android Logcat exports, and Linux Syslog formats.

Disclaimer & Acceptable Use:
