DS1UOV's Morse Trainer w/ Koch

The Morse Code Trainer app is designed to help learners improve their Morse code reception skills in a structured and measurable way. It follows the Koch method, which starts with a small set of characters and gradually increases in difficulty as the learner improves. This method is perfect for those who want to make progress and develop practical listening skills, without the need for an AI opponent to play against.

The app uses a level system that is tied to the learner's performance, ensuring that each step feels earned and stable rather than rushed. This allows learners to see their current level, the maximum unlocked level, and their overall progress at a glance. They can also select any unlocked level to review earlier characters and strengthen weak points before moving forward. This clear "next target" flow helps keep training focused and consistent.

Users can customize their audio and session settings to suit their ears and goals. They can adjust the training speed and choose a comfortable tone frequency for longer sessions. The app also offers preset options for beginners to experts, making it easy to find a setup that works without manual tweaking. Each session is designed to keep the learner's attention on what matters most - recognition accuracy under realistic timing.

The app provides a focused input experience with a dedicated on-screen character grid that only shows the characters available at the learner's current level. This reduces accidental inputs and allows for a more efficient practice session. Users can also pause and resume sessions cleanly, with visible timing and progress indicators to always know where they are in the run. Optional physical keyboard input support is also available for a more realistic training experience.

After each session, users can review detailed results with accuracy percentages and clear pass/fail feedback for level advancement. They can also compare what was sent versus what they typed and identify mistake patterns to understand which characters they confuse most often. If they qualify, they can immediately retry the current level, return home, or continue with the newly unlocked character.

The app also offers safe resets, allowing users to restart their learning from level 1 while keeping their app settings, or reset all settings back to default. This makes it easy to re-train from scratch, test new configurations, or share the device with another learner.
