Log Forge

LogForge is a USB serial console for Android. Plug in an ESP32, Arduino, STM32, or similar board, pick a baud rate, and watch the logs as they come in.

Open a console

• Scan connected USB serial devices

• Choose a preset baud rate or type a custom one

• Stream live output the moment the port opens

• Send commands with history and saved macros (reset, AT+GMR, help, and your own)

Work the logs

• Compact rows that stay readable while data is flying

• Search, pause, and clear without dropping the session

• Filter by level or tag

• Toggle timestamps and hex / raw view

• Jump to crash and exception lines, then copy the stack

• Pulse DTR/RTS to reset an ESP32-style board without unplugging

Keep what matters

• Closing a console saves the capture to Sessions

• Reopen old logs, add a name or note, share, or export to Downloads

• Recent devices are one tap from Home

• Light, dark, or system theme

Works with common USB-serial chips

FTDI, Silicon Labs CP210x, WCH CH340, Arduino, STM32 CDC, Raspberry Pi Pico, and Espressif native USB (ESP32-S2 / S3 / C3).

Your data stays on the phone. LogForge does not create an account, does not run ads or analytics, and does not upload logs. Sharing and export only happen when you choose them.

USB host permission is requested only for the board you select.
