Morse code practice with Koch lessons and simulated CW QSO scenarios.
KOCH LESSONS
Listen to a selected Morse character, key it from memory, and check your answer. Adjust character speed and effective speed as you practice.
MORSE KEYING
Choose a straight key or iambic touch paddles. Keyboard and standard HID input are also supported. Morse tones are generated on your device for playback.
SIMULATED QSO PRACTICE
Practice with a local bot in five scenarios: first contact, short contact, ragchew, contest, and POTA / SOTA. Send a practice call sign, exchange RST, and reply to scenario prompts. The bot generates a practice call sign and station details locally. This is a simulation: it does not transmit over radio or contact real stations.
PROGRESS AND LOGS
See completed lessons, unlocked Koch characters, daily goal progress, character accuracy, and badges saved on this device. Completed simulated contacts appear in a local log.
OPTIONAL ADIF EXPORT
Select one completed record and choose a destination in Android's document picker to export it as an ADIF file.
OFFLINE AND PRIVACY
Lessons, Morse keying, simulated bot practice, progress, and logs work offline. No account or analytics. No ads or in-app purchases. This is a one-time paid app; Google Play displays the current price.
