About this app
** What it is **
A Morse code trainer for your phone. Two modes, 52 lessons, real English words, and absolutely zero interest in your email address.
Receive mode: hear beeps, identify the letter. Like being a WW2 radio operator, except you're on the bus and nobody is counting on you.
Send mode: tap dots and dashes on your screen — or plug in a real straight key. The app checks your timing. It will be wrong at first. That's not a bug, that's learning.
** What's included **
52 lessons covering every letter, number, and punctuation mark in International Morse Code. You start with E, T, and A. By lesson 52 you'll know the Morse for the dollar sign. Whether that knowledge ever becomes useful is between you and the universe.
Practice mode for when you've finished the lessons and want to keep your edge. Sixty random characters from any category — letters, numbers, punctuation, or all of it. Receive or send. No unlocks to chase, no progress to record. Just you and the beeps.
Word practice, because letters in isolation only get you so far. Ten real English words per session, drawn from a list of sixteen thousand, sent as one continuous signal with proper letter spacing — the way Morse actually sounds. Receive them and type what you heard, or send them yourself, letter by letter. Get one letter wrong and the whole word starts over. Real operators didn't get to keep the first half either. The word list ships inside the app — nothing to download, nothing to sync.
Hardware key support. Plug a VBand or Vail adapter into your phone with a USB OTG cable and send with an actual straight key instead of glass. Any USB or Bluetooth keyboard works too — the spacebar makes a perfectly good key. If your adapter generates its own sidetone, you can mute the app's.
Straight keys for now. Iambic paddles need an electronic keyer inside the app, which is a bigger job than it looks.
Five speed settings, from 12 to 30 WPM. Shown in words per minute rather than "Slow," "Normal," and "Fast," because if you send at 25 you already know what that means, and if you don't, you'll find out soon enough.
A heart system keeps you honest — guess wrong too many times and you restart the lesson. No in-app purchase to buy more hearts. Just get better.
Every lesson gets a grade. SSS if you finish without a single mistake or hint, down to C if you barely made it. Your best grade stays on the lesson card. There's no leaderboard. Nobody else will see it. You will.
Dark theme and light theme. For midnight practice sessions and for people who believe light mode builds character.
The app follows your device language. Translations come via Google Play, so quality varies.

** What's NOT included **
No account. No login. No email. We don't know who you are and we'd like to keep it that way.
No subscription. You buy it once. It's yours. Remember when software worked like that? We do.
No ads. You will never watch a 30-second video about insurance between learning S and O.
No social features. Nobody needs to know you're learning Morse code at 2 AM. That's your business.
No internet required. Works fully offline. Learn on a plane, in the subway, or in a bunker. Especially in a bunker.
No gamification bloat. No daily streaks, no gems, no leaderboards, no push notifications guilting you into opening the app. Just lessons.
No AI. No chatbot. No "powered by machine learning." It's a sine wave and an if-statement. Sometimes that's all you need.
** Why this one? **
Because most Morse code apps on the Play Store either want a monthly subscription to teach you the letter E, blast you with interstitial ads after every lesson, or require you to create an account with a password you'll forget before you learn your first dash.
This one doesn't do any of that. It teaches Morse code. That's it. That's the app.
