Morse Code Reader and Decoder is an iPhone app for translating text to Morse code and Morse code to text, sending Morse signals with your flashlight, screen, vibration or sound, and learning Morse code with practice lessons at three difficulty levels. WHAT YOU CAN DO • Text to Morse code translator: type any word or sentence and see it instantly as dots and dashes. • Morse code to text decoder: enter dots and dashes and read the message as plain English text. • Morse code flashlight: send your message as light signals with the iPhone flashlight. • Screen blinking: flash your message on the screen, useful when you need a visible signal without the flashlight. • Vibration: feel Morse code as vibration patterns, for silent practice or sending. • Sound: hear Morse code as classic beeps to train your ear. • Saved signals: save messages you send often so you can replay them in one tap. • Learn Morse code: practice letters, words and full sentences. • Three difficulty levels: start with single letters as a beginner and move up to sentences as you improve. HOW IT WORKS 1. Type a message, or enter Morse code you want to decode. 2. Read the translation in Morse code or in text. 3. Send it with flashlight, screen, vibration or sound, or save it for later. 4. Open practice mode to learn the Morse alphabet step by step. WHO IT'S FOR • Beginners who want to learn the Morse code alphabet and practice every day. • Amateur (ham) radio operators and students preparing for CW practice. • Scouts, campers and hikers who want to know how to signal with light. • Puzzle fans, escape room players, geocachers and teachers who need a quick Morse code converter. • Anyone curious about Morse code who wants a simple translator on their iPhone. GOOD TO KNOW The flashlight, screen and sound signals are for learning, practice and fun. This app is not a safety or emergency device.
