Morse Code Trainer, CW Decoder

Morse code becomes far more useful when you can do more than look it up. MORSE gives you one clean workspace to translate a message, hear or send a signal, build real listening and keying skills, and keep the tools you need close at hand.

Translate and send right away
• Convert text to Morse code and Morse code back to text
• Work with seven writing and code systems: International Morse, Chinese telegraph code, Japanese, Korean, Russian, Greek and Arabic
• Send signals with sound, haptics, the flashlight or screen flashes
• Choose playback speed and carrier tone, or start with ready-to-use common phrases

Learn to hear it—not just read it
• Follow 174 structured lessons across 29 units and six activity types
• Build skills in Koch order through recognition, listening, comparison, sending, applied practice and challenges
• Progress from characters and numbers to punctuation, prosigns, Q codes, callsigns and complete QSOs
• Take a free 15-question daily test shaped by your current progress and previously learned weak points
• Track accuracy, best scores, course progress and practice streaks
• Pro unlocks the remaining 150 lessons, focused listening, Head Copy and weakness drills, plus full WPM, tone and Farnsworth controls

Read real signals when you need to
• See a provisional dot-dash and text preview while recording; after you stop, MORSE analyzes the full recording and produces a corrected result
• Import audio, video or images containing Morse signals
• Let MORSE analyze carrier tone and timing, with status and confidence feedback
• Core media analysis runs on your device instead of sending signal content to a cloud recognition service

Communicate, save and share
• Enter dots and dashes with a Morse key and see the decoded text as you type
• Exchange Morse messages directly with another nearby device; Pro adds optional 4-digit PIN content protection
• Keep history and favorites, then reopen an item to continue editing
• Export text and Morse signal cards for free; Pro adds WAV audio export
• Import or export a local backup of your training progress

Start free. Unlock Pro once.

MORSE is free to download. Core text conversion is unlimited, and basic signal output, character references, daily tests, the first 24 lessons and nearby communication without a PIN are free to use. Microphone, audio, video and image recognition share one successful free experience.

There are no ads, subscriptions or automatic renewals. MORSE PRO is a one-time non-consumable purchase that permanently unlocks Pro features. Your localized price is shown by the App Store, and previous purchases can be restored.
