Ditkey Morse Trainer

About this app

Ditkey is a calm, offline Morse-code trainer built around a single idea: you can learn to send and read Morse without making a sound. Every signal in the app is shown as a warm amber flash and felt as a gentle vibration, so you can practise on the bus, in a library, or late at night without headphones and without disturbing anyone.

There are no ads, no accounts, no sign-ups and no internet permission. Open the app and start learning.

WHAT'S INSIDE

Learn
A complete chart of the International Morse alphabet — every letter A to Z, the digits 0 to 9, and the common punctuation marks. Tap any character and Ditkey plays its pattern back to you: the lamp flashes the dots and dashes in real time while the phone taps out the same rhythm. It's the fastest way to fix a new character in memory.

Straight Key
A vintage brass telegraph key you actually operate. Press and hold the knob — a short tap is a dot, a longer hold is a dash. Ditkey watches your timing, groups your taps into letters and words, and shows the decoded text as you go. It's a genuine feel for keying, right on the glass.

Translate
A two-way converter. Type plain text and read it back as Morse, or paste in dots and dashes and turn them into words. Swap direction with one button and copy the result to share it anywhere.

Sending Drill
A timed quiz that sharpens both directions of your skill. Some questions show you a code and ask for the character; others show a character and ask for the code. Answer as many as you can before the clock runs out, and Ditkey remembers your best score.

Awards & About
Track your progress: which characters you've practised, how many drills you've finished and your personal records. Unlock milestones as you go from your first signal to a full-deck, sharp-eared operator.
