Daily Morse Code Review
A few minutes a day. You hear a character and press its key. The ones you know come back less often, the ones you miss come back sooner, so every character returns just before you would forget it. Every drill on the site feeds the same schedule.

How the spacing works
Each character climbs seven steps. After each step it waits longer before it comes back: 10 minutes, 8 hours, then 1, 3, 7, 16 and 35 days. A right answer within 1.5 seconds of the end of the character moves it up a step; a right but slower one keeps it where it is; a miss sends it back to step 1. This is a Leitner schedule, the method behind flashcard boxes, and it moves characters into long-term memory with the fewest reviews.
The Koch course, the recognition drill, listening practice, the quiz and the keyer all feed the same schedule, and each answer counts towards your daily goal and streak. Progress is saved on this device only.
Tips
- Answer from the sound, not by counting dots and dashes: the quick answers are the ones that count as known.
- Keep the speed at 20 WPM or more, so each character is one sound.
- Daily beats long: five minutes every day does more than an hour once a week.
- New to Morse? Start with the Koch course: the characters it teaches join the schedule as you go.
