📻 DS1UOV’s Morse Trainer
Train Morse code reception in a structured way using the Koch method, designed for learners who want measurable progress and practical CW listening skills (this app does not include an AI opponent to play against).
✅ KOCH METHOD, DONE RIGHT
Start with a small character set, build accuracy, then unlock the next character only when you are ready.
Your level system is tied to performance, so each step feels earned and stable rather than rushed.
🎯 LEVELS, PROGRESS, AND SMART REVIEW
See your current level, max unlocked level, and overall learning progress at a glance.
Select any unlocked level to review earlier characters and strengthen weak points before moving forward.
A clear “next target” flow helps keep training focused and consistent.
⚙️ CUSTOM AUDIO & SESSION SETTINGS
Tune your practice to your ears and your goals: adjust training speed settings and pick a tone frequency that is comfortable for long sessions.
Use presets (beginner to expert) when you want a proven setup without manual tweaking.
Each session is built to keep your attention on what matters—recognition accuracy under realistic timing.
⌨️ FOCUSED INPUT EXPERIENCE
Practice with a dedicated on-screen character grid that only shows the characters available at your current level, reducing accidental inputs.
Pause and resume sessions cleanly, with visible timing/progress indicators so you always know where you are in the run.
Optional physical keyboard input support lets you train like real operating, especially on tablets or with external keyboards.
📊 RESULTS THAT HELP YOU IMPROVE
After each session, review a detailed results screen with accuracy (%) and clear pass/fail feedback for level advancement (90% threshold for unlocking the next character).
Compare what was sent vs what you typed, and inspect mistake patterns to understand which characters you confuse most often.
Retry the current level immediately, return home, or continue with the newly unlocked character when you qualify.
🧹 SAFE RESETS, WHEN YOU NEED THEM
Reset only Koch progress to restart learning from level 1 while keeping your app settings, or reset all settings back to defaults.
This makes it easy to re-train from scratch, test new configurations, or share the device with another learner.
