What Morse code is: International Morse code represents letters with short signals (dots) and long signals (dashes). Each letter has its own pattern, such as A = .-, N = -., and S = ....
How a session works:
- Reading rounds show Morse code and ask you to type the letter, word, or message.
- Sending rounds show text and ask you to produce the Morse code. Choose Typing to enter dots and dashes directly or use the on-screen Dot, Dash, Letter Gap, and Word Gap controls; choose Keying to use the tap-and-hold Morse key.
- In Morse answers, use a space between letters and a slash between words. Extra spacing around separators is accepted.
- Easy uses single letters and short words. Medium uses words and short messages. Hard uses longer words and messages. Mixed balances all three.
- Training mode marks each round immediately and shows the full conversion. Test mode holds feedback until the results screen.
- The Morse reference is shown during Training by default. Advanced Settings can hide it during Training; Test mode always hides the reference.
- Reading answers ignore capitalization, spaces, and punctuation. Sending answers must contain the correct dots, dashes, and letter/word boundaries.
- Press Enter to submit, then Enter again to move on. Skipping marks the round wrong.
- If you switch away from the tab during a timed round, the clock pauses until you come back.

Tips for getting faster:
- Start with the shortest patterns: E =
., T = -, I = .., A = .-, N = -., M = --.
- Learn patterns as complete sounds or shapes instead of counting individual dots and dashes whenever possible.
- Practice Reading and Sending separately if one direction is weaker, then switch to Mixed once both feel comfortable.
- In Keying mode, make deliberate short taps for dots and clearly longer holds for dashes before adding the letter gap.
