Dit vs Morse Invaders

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.

Invaders are falling. Your only weapon is Morse code. Morse Invaders is a Space-Invaders-style arcade game that teaches you real Morse code as you play. Every falling invader carries a letter or a word — key in its dot-dash pattern before it reaches the bottom, and it explodes. Miss it, and you take the hit. There's one control: a single telegraph-style key. Tap it for a dot, hold it for a dash — just like a real operator. No menus of buttons, no busywork. Just you, the key, and the code. HOW TO PLAY • Tap the key for a dot, hold it for a dash • Match an invader's full Morse pattern to destroy it • Tap a falling invader anytime to reveal its code if you get stuck • Survive as many waves as you can and chase your high score THREE WAYS TO PLAY • Learning Mode — letters are introduced gradually using the Koch method (the standard order for training your ear to recognize Morse code), with periodic quiz waves that hide the hints to test what you've actually learned • Normal Mode — all letters in play, hints available on tap • Words Mode — full common English words fall instead of single letters, and you key in the entire word as one continuous stream of dots and dashes Fall speed adjusts to difficulty automatically — longer patterns with more dashes fall slower, giving you time to think through trickier code. NO CATCH Morse Invaders is completely free, with nothing locked behind a purchase. No ads, no accounts, no data collection of any kind. If you enjoy it and want to help keep it on the App Store, there's an optional one-time note with a link to buy the developer a coffee — entirely optional, never required. Whether you're a ham radio operator brushing up, a student learning Morse code from scratch, or just want an arcade game with a real skill behind it, Morse Invaders turns practice into something you'll actually want to play.
