Dit teaches Morse code by ear, not by eye. There's no need to memorize a dot-and-dash chart. You hear each character as a sound and tap it back. Characters play at real speed from the start. If they played slowly enough to count individual dots and dashes, you'd do exactly that, and then you'd be stuck translating forever instead of just hearing the letter. The spacing between letters starts generous and tightens as you improve. There are three modes in Dit. Practice walks you through the alphabet and advances when you're ready. Freestyle lets you tap whatever you want and see what it decodes to. Listen plays a character and you type what you heard. The app notices which letters trip you up and brings them back more often. Review Misses just drills your weak spots. It tracks how quickly you recognize each character, so you can tell where you're sharp versus where you're still guessing. Letters are introduced by frequency in real radio contacts, not alphabetically. R, E, A, T, I, N come early, so you're spelling actual words within a few minutes. Works offline.
