Store description excerpt
Learn international Morse code in both English and Korean alphabets — one app, two character sets, two practice modes. Most Morse trainers ship English-only. Korean Morse follows a separate 24-character set (14 consonants + 10 vowels), and is used by Korean ham radio operators (CW) and amateur radio licensees. Morse Trainer teaches both side-by-side, so bilingual learners and Korean radio operators can practice the alphabet they actually need. ▸ FOUR CATEGORIES • English: 26 letters (A–Z) • Korean: 24 characters (ㄱ–ㅎ consonants + ㅏ–ㅣ vowels) • Numbers: 10 digits (0–9) • Punctuation: 8 symbols ( . , ? ! / ( ) = ) ▸ TWO LEARNING MODES • Visual mode — animated dot/dash pulses. Watch the rhythm before you hear it. • Audio mode — pure-tone Morse playback (500–800 Hz, adjustable 5–30 WPM). The same sound used in amateur radio CW practice. ▸ SMART QUIZ • 4-choice flashcards with instant color feedback (green = correct, red = wrong). • Spaced repetition (SM-2 lite algorithm) — frequently-missed characters resurface more often, so practice time goes to where it matters. • Configurable session length (10 / 20 / 50 / 100 questions per session). ▸ DICTIONARY • Tap any category chip to filter (English / Korean / Numbers / Punctuation). • Search by letter or Morse pattern. • Tap to hear the sound and see the dot/dash visualization. ▸ TRANSLATOR • Text → Morse: type or paste any string, get the encoded Morse line-by-line. • Morse → Text: decode incoming patterns to readable text. ▸ STATISTICS • Track session accuracy, time per session, characters mastered. • Per-category progress so you can see which set needs more drilling. ▸ APP PHILOSOPHY • 100% offline — no sign-up, no internet connection needed, no cloud account. • No in-app purchases, no subscriptions, no paywalls. • Korean + English UI, light + dark theme, system theme follow. • Adjustable speed (WPM) and tone frequency to match your hearing preference. ▸ WHO IT'S FOR • Beginners learning Morse code for the first time • Ham radio operators preparing for CW (Continuous Wave) practice • Korean amateur radio licensees needing the Korean alphabet drill • Scouts working on signaling badges • Students and hobbyists curious about the original digital encoding ▸ PRIVACY The app stores progress locally on your device using Hive storage.
