## Description

<b>📻 DS1UOV’s Morse Trainer</b><br>​<br>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).<br><br>​<br><br><b>✅ KOCH METHOD, DONE RIGHT</b><br>​<br>Start with a small character set, build accuracy, then unlock the next character only when you are ready.<br>​<br>Your level system is tied to performance, so each step feels earned and stable rather than rushed.<br><br>​<br><br><b>🎯 LEVELS, PROGRESS, AND SMART REVIEW</b><br>​<br>See your current level, max unlocked level, and overall learning progress at a glance.<br>​<br>Select any unlocked level to review earlier characters and strengthen weak points before moving forward.<br>​<br>A clear “next target” flow helps keep training focused and consistent.<br><br>​<br><br><b>⚙️ CUSTOM AUDIO &amp; SESSION SETTINGS</b><br>​<br>Tune your practice to your ears and your goals: adjust training speed settings and pick a tone frequency that is comfortable for long sessions.<br>​<br>Use presets (beginner to expert) when you want a proven setup without manual tweaking.<br>​<br>Each session is built to keep your attention on what matters—recognition accuracy under realistic timing.<br><br>​<br><br><b>⌨️ FOCUSED INPUT EXPERIENCE</b><br>​<br>Practice with a dedicated on-screen character grid that only shows the characters available at your current level, reducing accidental inputs.<br>​<br>Pause and resume sessions cleanly, with visible timing/progress indicators so you always know where you are in the run.<br>​<br>Optional physical keyboard input support lets you train like real operating, especially on tablets or with external keyboards.<br><br>​<br><br><b>📊 RESULTS THAT HELP YOU IMPROVE</b><br>​<br>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).<br>​<br>Compare what was sent vs what you typed, and inspect mistake patterns to understand which characters you confuse most often.<br>​<br>Retry the current level immediately, return home, or continue with the newly unlocked character when you qualify.<br><br>​<br><br><b>🧹 SAFE RESETS, WHEN YOU NEED THEM</b><br>​<br>Reset only Koch progress to restart learning from level 1 while keeping your app settings, or reset all settings back to defaults.<br>​<br>This makes it easy to re-train from scratch, test new configurations, or share the device with another learner.<br><br>​<br><br><b>Start today</b><br>​<br>Make steady, data-driven progress in Morse reception with a modern UI and a methodical training flow built around real learning principles.<br>​
