SerialFlow - Turn your Android into a portable serial debugging station.

SerialFlow is a modern USB serial terminal that turns your Android device into a portable debugging workstation. Built for developers working with Arduino, ESP32, STM32, and IoT hardware. Monitor data, send commands, and find key info using fast regex filtering and protocol decoding (Modbus, NMEA). Pro features unlock real-time waveform visualization, 3D attitude tracking, and GPS diagnostics.
