Test your Morse code skills. Listen to audio signals and type the correct answer. Track your score and improve your speed.
The quiz plays Morse code audio and you type what you hear. Choose between single characters, full words, or a 20-round speed test. Your score, accuracy, and streaks are tracked in real time.
Start at 15-20 WPM from day one, even if you only know two or three letters. Slow characters teach you to count dots and dashes, and that habit stalls most learners around 10 WPM. Once you pass 90% accuracy, add a new letter instead of slowing down. Why starting at full speed works
Speed test mode plays 20 rounds of Morse code as fast as possible. It measures how quickly and accurately you can decode signals, perfect for tracking your progress over time.
