Morse Mania vs Doomsday Method | Mental Game

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). Less than 20 is not recommended though, as it doesn't help you to actually learn the language. - Adjustable sound frequency: 400 to 1000 Hz. - Adjustable Farnsworth speed: from 5 to 45 WPM. Determines how long are the spaces between letters. - Adjustable difficulty level for sending the Morse code. - Disable/enable the progress circle in Settings. - Settings for progress speed, review time, time pressure and lives in challenges. - Setting for background noise: to better support some Bluetooth earphones that keep disconnecting from the phone while you play, or just to make it more challenging. - Ability to jump to the past levels to revise, or skip some if you're already familiar with certain characters. - Ability to reset mistakes and levels. ---------------------------- Read our dedicated blog posts to get the most out of the game.

Someone tells you the date they were born. You tell them it was a Monday. That is a real skill, it takes about a week to learn, and this app teaches it end to end. The Doomsday algorithm — invented by the mathematician John Conway — turns any date into its weekday using arithmetic small enough to finish while someone is still saying the date. No lookup. No phone. No calendar. LEARN 48 lessons across 11 chapters, in three parts 178 checkpoint questions. You answer in your head, then check yourself against the worked reasoning — nothing is graded, and nothing is rushed Interactive calendars, anchor tables and step-by-step walkthroughs inside the lessons themselves Mnemonics that stick: 4/4, 6/6, 8/8, 10/10, 12/12, and "9-to-5 at the 7-Eleven" Six different ways to work the year offset. Pick the one your head likes, and every worked explanation in the app is rewritten in it Seven Extras: why the method works, Easter and the computus, the Julian calendar, Conway's own shortcuts, the record holders, and full reference tables A cheatsheet with every anchor and every offset on one screen TRAIN 10 drills: weekday numbers, counting in sevens, leap years, century anchors, the year offset, month doomsdays, day counting, reverse dates, Julian dates and Easter Five stars a drill, earned by answering cleanly — right, and inside that drill's target time Nothing cuts you off mid-question, and training never costs you rating PLAY Classic — endless real dates, at your own pace, with no clock at all Daily Challenge — five dates drawn from the day itself, identical for every player on earth, one attempt a day Time Attack — two minutes, as many dates as you can, ten seconds off for every miss Choose your range: 2000–2099, 1800–2199, or the whole Gregorian calendar from 1583 to 2599 YOUR PROGRESS A Doomsday Rating that rises when you are right and quick, and never pays for a guess Accuracy and speed over time, your rating history, and a 12-week activity calendar Game Center leaderboards for today's challenge and the global rating, friends included BUILT PROPERLY No account, no sign-up, no ads Works offline Every number in every lesson is re-derived by a checker that shares no code with the app, so an explanation cannot drift from the answer it gives Analytics are opt-in, pseudonymous and on EU servers.
