The keying drill: a large letter A above a white paddle.The listening drill: a play button above a keyboard of unlocked letters.The unlock moment: the question Which one was it? above three guesses, F, R and U.

How it works

  1. Key it.

    One big paddle. A short press is a dit, a long one a dah. The app learns your rhythm from your first presses and judges against it.

  2. Hear it.

    A 600 Hz tone, and the lamp blinks in time with it. You answer from a short row at first, then from a keyboard of everything you know.

  3. Unlock it.

    Koch method: K and M first, the rest one character at a time when your recent accuracy is high. All 26 letters and 10 digits, digits mixed in along the way.

  4. Nothing else.

    No accounts, no tracking, no ads, no streaks. Progress lives on the phone, and the app works entirely offline.
