Morse Machine 1.0.0.2

This application provides a systematic approach to learning Morse code by focusing on auditory reception skills. It begins with a foundational set of two letters and incrementally introduces additional characters as the user demonstrates readiness, promoting efficient skill acquisition.

The design prioritizes personalized practice, avoiding the redundancy of reviewing already mastered material or becoming overwhelmed by unfamiliar content. Its methodology is rooted in the principles established by Ward K9OX (http://c2.com/morse/), utilizing primarily the Koch algorithm with originating sequences starting from the first two letters: K and M. Users also have the option to select alternative learning methods and access specialized training for the top 40 words commonly used in CW QSO.

Visual feedback is incorporated through a circular chart surrounding each letter, indicating the current error score—initially at 100%, diminishing as correct responses are achieved, and increasing with mistakes or delays in recognition.

Training begins with a simple tap of the PLAY button located at the top right of the interface. The app then plays Morse tones, and users respond by selecting the corresponding letter or word. Incorrect responses trigger an error tone, while correct ones prompt continuation with subsequent characters. As proficiency improves, additional letters are gradually introduced based on the selected method.

Users can pause or stop practice sessions at will via dedicated buttons. Additionally, a SESSION TIME setting allows for automatic session termination after a user-defined duration.

Outside of active training, the app enables users to listen to individual tones by selecting specific keys or words, fostering familiarization outside structured lessons.

Settings are accessible through the hamburger menu icon located at the top left corner, allowing customization of various parameters. The interface also features a "Best Scores" section to monitor top achievements.

The application supports both landscape and portrait orientations, ensuring flexible usability across devices.

Overall, this tool offers a focused and adaptable environment for developing proficiency in Morse code reception.
