Morse code practice that gives every session a purpose.

Review the sounds you need most

Weak sounds practice asks you to type the characters you hear. The selection favors recently introduced sounds, sounds with lower accuracy, and sounds due for review. Each session has twelve signals drawn from the characters you have introduced.

Try to recall the answer before looking at a visual aid. If you miss a character, listen again and compare it with the answer. A mistake is useful information about what to revisit; it is not a reason to restart your entire learning journey.

The app tracks single-character listening separately from sending. Successful recall after a gap can extend a sound’s review interval. Immediate repeated answers do not keep pushing that interval forward, so returning on another day matters.

Move from characters to words

Words & groups practice uses words made from your introduced characters. When there are not enough characters for a word, you hear a short group of familiar characters instead. These twelve-question sessions help you hold several sounds in memory and connect them into a complete answer.

Listen for the spacing between letters. Try typing the whole signal, and avoid assuming the word from its first letter. If words feel overwhelming, spend a little longer on single-character review, or widen the spacing in sound settings.

These labelled examples are for comparison. In a practice exercise, the answer is withheld until you respond.

Try complete messages when ready

Short messages practice contains six messages using the full alphabet. It is an optional stretch, even if you have not introduced every character in Learn mode. You might hear a greeting or a short radio-style phrase, then type the message you recognized.

Notice the larger gaps between words. If one letter escapes you, try to keep following the rest of the message rather than mentally rewinding while new sounds arrive. Use the replay to check your uncertain parts. A comfortable spacing speed can help you practice this without changing the rhythm inside each letter.

Send a signal of your own

Sending practice uses a touch button or the space bar as a Morse key. At the app’s 12 WPM sending clock, aim for a 100-millisecond dit and a 300-millisecond dah. Release the key between elements and check the transmission when the character is complete.

The app recognizes the pattern and reports a timing match. It is an introduction to controlled sending, not a substitute for checking your complete spacing and technique with an experienced operator. A correct checked character advances automatically; a mistake remains available for review.

Use daily competition as a check-in

The daily challenge offers one official ranked round per guest per UTC day, with separate divisions. Everyone in a division receives comparable signals at fixed timing. Exact answers earn the score; a smaller speed bonus is available for highly accurate rounds.

Listening exercises replay automatically after a four-second pause. In a ranked round, replaying or pausing does not stop the server’s answer deadline. Practice modes remain available whenever you want to work on a difficult sound without an official score.
