Doomsday 2.0 is a complete rewrite. Everything below is new. A REAL COURSE 48 lessons across 11 chapters, with 178 checkpoint questions, interactive calendars inside the lessons, and seven Extras — why the method works, Easter and the computus, the Julian calendar, Conway's own shortcuts, and the people who hold the records. Plus a cheatsheet with every anchor and every offset on one screen. TRAINING THAT DIAGNOSES 10 drills — one for each step of the method, the three fundamentals underneath it, and the three it opens up: reverse dates, Julian dates and Easter. Five stars each, earned by answering cleanly rather than merely correctly, so the bar tells you which step is actually slowing you down. And no drill cuts a question off any more. THREE WAYS TO PLAY Classic is endless and now has no clock at all. The Daily Challenge gives every player on earth the same five dates. Time Attack is two minutes, with ten seconds off for every miss. A RATING THAT MAKES SENSE One Doomsday Rating, explained in four lines: right and quick is worth most, wrong is worth nothing, and no single answer can move it by more than a fixed amount. Alongside it, accuracy and speed trends, rating history and a 12-week activity calendar. SIX METHODS, YOUR CHOICE Choose how you work the year offset, and every worked explanation in the app is rewritten in your method. COMING FROM VERSION 1 Your old history is imported and replayed answer by answer through the new rating, so your chart reaches back into version 1 and your rating arrives honest rather than reset. Also new: no account, no ads, works offline, and analytics that are opt-in and stay on EU servers.
