SimpleCW vs Morse Translator

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.

Turn text into Morse code and translate dots and dashes back into readable messages. Hear your message, flash it on your phone, or share it as an audio file. TRANSLATE BOTH WAYS Type a message to see its Morse code as you write. Enter dots, dashes and spaces to translate Morse back into text. Supports letters A–Z, numbers and common punctuation. Accented Latin letters use their basic form, and unrecognised characters are highlighted. HEAR AND SHARE YOUR MESSAGE Play Morse code audio with adjustable speed and tone. Stop playback whenever you need to. Share your message as a WAV audio file through compatible apps. Audio messages are limited to two minutes. SEND LIGHT SIGNALS Flash your message on the screen or use your phone's torch. Choose screen colours and repeat your message while the signal screen is open. Torch signals require compatible hardware and camera permission; torch speed is limited to 10 WPM. SAVE YOUR GO-TO MESSAGES Keep favourites and revisit recent messages. Open a saved phrase, edit it and send it again. Messages and learning progress are stored on your phone. PRACTISE THE MORSE ALPHABET Tap letters, numbers and punctuation in the chart to hear their sounds. Try five-question listening quizzes, choose your character set and practise characters you missed. Use the manual Morse key to explore dots, dashes and gaps. USE IT YOUR WAY Choose light, dark or system appearance. Core translation, audio, reference and practice work offline. Online dictionary links require an internet connection. An experimental sound decoder is available in Settings for slow, clear signals. It detects volume changes rather than isolating a Morse tone, so background noise can affect its results. Microphone access is optional and recordings stay on your phone. For learning the alphabet, solving Morse puzzles and sharing messages with friends.
