Description

Read Morse and digital-mode signals from audio with SimpleCW (formerly HamChat). Tune one receiver, watch the waterfall, and follow decoded text in the transcript.

CW includes automatic tone acquisition or manual tuning, Otsu and Bayesian decoders, a live keying trace, speed estimates, and input-level feedback. An optional on-device ML CW decoder is included with Premium Modes Unlock on iOS 18 or later and macOS 15 or later. Decoder results depend on signal quality and sending style; Otsu is the default.

Receive CW, PSK31/63, MFSK, Olivia, and RTTY. Classical receive in every mode and CW transmit remain free. A three-minute trial lets you try other transmit modes. The existing one-time Premium Modes Unlock purchase adds unlimited digital-mode transmit and the optional ML CW decoder.

Use the microphone or a compatible audio interface. On Mac, System Audio can receive audio from other software with the appropriate system permission. Audio processing stays on the device. Copy or share the resulting transcript.
