MorseKeyer
This app simulates an electronic telegraph keyer with a dual-lever paddle for sending Morse code. It offers various keying modes, buffers paddle presses for higher speeds, and displays transmitted symbols, including international Morse code and extensions for multiple languages. It also recognizes and formats abbreviations used in amateur radio and other communications.
- Dual-lever paddle simulation
- Dot and dash memories
- Multiple keying modes (iambic, ultimatic, bug)
- Buffered paddle presses for speed
- Support for international Morse code and language extensions
- Recognition of CW abbreviations and prosigns
- Smart text formatting and dynamic alphabet switching

The app operates like a real electronic keyer with a dual-lever paddle, dot and dash memories and various keying modes including "iambic". It produces a series of short sound signals (dots) when one of the paddles is pressed and a series of long signals (dashes) when the other one is pressed. Letters, digits, procedural signals (prosigns) and other transmitted symbols are displayed on the screen. Additionally, Morse code abbreviations used in amateur radio, maritime, aviation and military communications are recognized and formatted appropriately. ADVANCED CW KEYER The keyer buffers paddle presses, that eases the manipulation and helps to transmit at higher speeds. High accuracy of generated signals contributes to high-quality transmission of Morse code. Keying modes: - Ultimatic — "last paddle wins" - Iambic (modes A and B) - Single lever - Semi-automatic, aka "bug" EXTENDED MORSE CODE When displaying the transmitted text, the app "knows" in addition to International Morse code a number of extensions for different languages. Supported alphabets include Japanese (Wabun code), Greek, Cyrillic-based and Latin-based alphabets with diacritical marks. The app recognizes details and nuances of Morse code for the following alphabets: Belarusian, Bosnian, Bulgarian, Croatian, Czech, Danish, Dutch, English, Esperanto, Estonian, Finnish, French, German, Greek, Hungarian, Icelandic, Italian, Japanese, Latvian, Lithuanian, Macedonian, Moldovan, Montenegrin, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Turkish, Ukrainian. SMART DISPLAY MorseKeyer does a lot to display the Morse code you transmit in the most readable form. For this purpose the app is equipped with the following functions: - Sophisticated text formatting - Dynamic switching between alphabets - Reasonable representation of errors These innovative features use multilevel content analysis to detect CW abbreviations, Q-codes, Z-codes, amateur radio callsigns and other special words. SOPHISTICATED TEXT FORMATTING The transmitted text can be displayed not only in the traditional all-capital format, but also using a kind of "smart" formatting. In this mode each word is displayed in the accepted form, as in the following CW session snippet: GM dr OM tnx fer call = ur RST is 599 = my QTH is nr London DYNAMIC SWITCHING BETWEEN ALPHABETS Even if you choose to use a non-Lating version of Morse code in your communication session, special words and Morse code abbreviations still can be displayed in Latin script. - In Wabun code the prosigns DO and SN as well as codes for Japanese parenthesis indicate switching between International and Japanese alphabets. MorseKeyer follows this convention and switches alphabets in such cases automatically. - A Cyrillic alphabet can be selected as the primary one to display most of the transmitted text, but all Morse code abbreviations and special words (CQ, de, ur, RST, my, QTH, name, tnx, etc.) as well as callsigns can still be represented in Latin script. REASONABLE REPRESENTATION OF ERRORS If you transmit a non-existent Morse code sign, the app displays it either as a dot-dash sequence or in another form depending on the current settings. In many cases MorseKeyer highlights a mistake, indicating its source and making it readable. ADVANCED SETTINGS MorseKeyer is ready to use out of the box. However, it has a lot of settings allowing you to fine tune it, customize and make more convenient in different use cases. NICE SOUND A special attention in the app is paid to the sound signal quality, its timbre, the optimal level of clicks and other characteristics, that make the sound of Morse code authentic and recognizable by any radio operator and comfortable to listen to.

Morse Maven offers a complete suite of tools to help you learn and master Morse code at your own pace. Learn, practice, and perfect your Morse code skills with our comprehensive app designed for everyone from beginners to advanced operators. Whether you're just starting out or aiming for high-speed copying, Morse Maven offers a complete suite of tools to help you learn and master Morse code at your own pace. Key Features: Beginner to Advanced Learning: The app provides progressive lessons for every skill level. The beginner's training course specifically uses the Koch method to teach the International Morse Code alphabet, numbers, punctuation, and common prosigns. With consistent practice using Morse Maven, beginners can learn to recognise all characters in about 1-2 months, and the app guides you through developing speed and fluency. Customizable Settings: Adjust character speed (WPM), Farnsworth spacing, and tone frequency to match your preferences. Farnsworth spacing is a method where individual characters are sent at a higher speed but with extra spacing between characters and words, which helps beginners recognise sound patterns while giving them time to process. Audio Morse Training: Practice receiving Morse code by ear with clear, adjustable audio tones. Morse tones are "shaped" with a raised cosine filter for easy listening. Morse Decoding Tool: Automatically decode received audio or flashlight Morse code messages using a Goertzel decoding algorithm. This tool also helps you check your sending accuracy. Sending Tool: Type text to send messages in Morse code by sound or flashlight. Reference: Access a complete listing of International Morse Code characters for quick reference. The Morse sending, decoding the reference features are free, always. You get three hours of complimentary access to our Learning & Improving features. To unlock unlimited access to everything, you can purchase a one-time upgrade for a small fee directly in the app. This helps us keep the app running smoothly and develop even more great features.
