iOS and Android Logs for Capacitor Apps

Pick the log channel that actually carries the message you need, filter to the app, capture to a file, hand off to diagnosis.

When to Use

TRIGGER when:

• User asks how to view, stream, filter, or save device/simulator logs.
• console.log output or ⚡️ Capacitor lines are missing on iOS/Android.
• User needs a crash report (.ips, tombstone, ANR) from a device or simulator.
• Logcat or the unified log is too noisy; user wants only their app or plugin.
• A log command fails or misbehaves: --level error still shows everything, unable to find utility "devicectl", Error: Unexpected argument 'log', adb: no devices/emulators found.

Do not use:

• Interpreting the error and fixing the app -> debugging-capacitor.
• Production crash/ANR reporting (Sentry, Crashlytics, Datadog) -> capacitor-native-observability.
• AI agent log streaming via MCP servers -> capacitor-mcp.
• CPU/memory profiling -> capacitor-performance.
• UIScene lifecycle migration -> capacitor-uiscene-migration.
