LogCat Analyzer: Debug Toolkit

LogCat Analyzer is a mobile debugging toolkit that turns raw logs into actionable insights. Open a log file, paste log text, or record your phone's logcat live — then instantly see crashes, performance issues and bugs, with explanations and fixes, right from your phone. ▶ NEW: LIVE LOGCAT (ANDROID) Record this phone's system log in real time — no computer needed while you test. • Start recording, open the app you're debugging, come back: everything is captured • Instant crash and ANR alerts from other apps • Filter by level, text, tag or package while recording; scrolls like Android Studio's Logcat • Save & analyze with one tap, with your real device's model and Android version • One-time setup: grant log access once from a computer with adb (step-by-step guide and copyable command in the app) ▶ INTELLIGENT ISSUE DETECTION Automatically scans every log for 6 types of issues: • Crashes — NullPointerException, IndexOutOfBounds, Fatal Signals with full stack traces • ANR — Application Not Responding with root cause identification • Memory Pressure — GC thrashing, low memory warnings, OutOfMemoryError • Network Errors — timeouts, DNS failures, SSL errors, HTTP 4xx/5xx • StrictMode Violations — disk/network on main thread, dropped frames • Infinite Loops — repeated error patterns and retry storms Each issue includes a severity badge, occurrence count, root cause and a suggested fix.
