In both the receiving and sending modes, the app starts with the easiest letters (E and T) and moves to more complicated ones. Once you master all the letters, it teaches you numbers and other symbols, and then proceeds to Prosigns, Q-codes, abbreviations, words, Callsigns, phrases and sentences. ---------------------------- Features: - 135 levels teach you to recognize (receive) 26 Latin letters, numbers, 18 punctuation marks, 20 non-Latin extensions, procedure signs (prosigns), Q-codes, most popular abbreviations, words, callsigns, phrases and sentences. - Another 135 levels teach and train you to send the Morse code. - 5 output modes: audio (default), blinking light, flashlight, vibration and light + sound. - 7 different keys for sending Morse code (e.g. iambic key). - 52 challenge levels test and consolidate your knowledge. - Custom level: create your own level to practice symbols of your choice. Save your own list of symbols and load anytime. - NEW! “Playground” to test and train your Morse code sending skills. - Smart learning: custom level choice is pre-populated with symbols where you made the mistakes most recently. - Support for external keyboard. - Hints (for free!) when you need help. - Explore mode: if you want to hear the symbols, or see a list of prosigns, Q-codes & other abbreviations and hear their sound representation. - 4 themes to choose from, from bright to dark. - 9 different keyboard layouts: QWERTY, AZERTY, QWERTZ, ABCDEF, Dvorak, Colemak, Maltron, Workman, Halmak. - Randomize letter/symbol positions for each level (to ensure you're not just learning the position of the symbols on the keyboard). - Absolutely no ads. - Works completely offline. ---------------------------- Completely customize the app: - Adjustable speed: from 5 to 45 WPM (words per minute).
