About this app

Discover the rhythm of dots and dashes with Morse Code, an offline translator and practice app for Android.

TRANSLATE TEXT AND MORSE
Convert text into international Morse code, or decode Morse into readable text. Let the app detect the translation direction, or select it yourself. Copy, paste and share your results, and open text shared from other apps. The translator supports letters, numbers and standard punctuation. Vietnamese accents are normalized to Latin letters, and unsupported characters are clearly identified.

HEAR AND SEND SIGNALS
Play your message as an audio tone, camera flash or vibration when your device supports the selected output. Adjust character speed, spacing speed and tone frequency. Farnsworth spacing gives you more time between characters while keeping the character rhythm. Export short messages as WAV audio files.

PRACTICE AT YOUR OWN PACE
Work through 35 levels with three practice modes:
- Recognition: read the Morse pattern and choose the character.
- Listening: hear a signal and identify the character.
- Sending: use short and long presses to send the requested character.

Each lesson contains 10 questions. Replay signals when you need to, review your answers and return to characters that need more practice.

USE A MANUAL MORSE KEY
Press and hold to send dots and dashes yourself. See your signal and decoded text as you practice timing and spacing.

KEEP A REFERENCE CLOSE
Browse the international Morse alphabet, digits and punctuation. Search for a character or code, listen to its signal and copy it. Explore 15 common Q-codes with their meanings and question forms.

FOLLOW YOUR PROGRESS
View completed practice sessions, accuracy, practice time and a seven-day chart. Review weaker characters and inspect past results. Export or import your learning history as JSON.

MAKE IT COMFORTABLE
Choose a light, dark or system theme. The interface automatically follows your device language and supports 20 languages. Your settings and learning history are stored on your device. No account or internet connection is required, and the app contains no ads.

Designed for learning and everyday Morse practice. The app uses international Morse timing based on ITU-R M.1677-1. Flash and vibration depend on your device hardware; camera permission is requested when using the flashlight.
