Equations keep coming, and you answer the one you saw a few turns ago while calculating the next. Memorising and calculating at the same time, a dual task that keeps your head working. This is the N-back task, a working memory exercise. SLEEP & SCORE (APPLE HEALTH) - Reads sleep and steps from Apple Health. "Sleep & Score" in the Review tab shows last night's sleep, today's steps, and your accuracy by how long you slept - "What Health reveals" answers questions from your own records, such as how many hours of sleep make you sharpest and how far two short nights pull your score down (Premium) - Saves how your mind feels after each round to Apple Health as State of Mind - Health data stays on this device and is never sent anywhere. Not for medical use KNOW YOUR MENTAL CONDITION - After every round, slide along a color band to record how your mind feels, from foggy to clear - "When your mind feels clear" ranks when you most often feel clear, such as mornings, your first round of the day, or after a break - "Mood and score" plots each round so you can check whether clearer rounds score higher THREE INPUT MODES - Tap: answer quickly with number buttons - Writing: write the digit on screen with your finger - Listening: the equation is read aloud and never shown. Keep your eyes closed, listen, remember, and write BUILT FOR HABIT - One short session a day - Streak counting - Record how your head feels after each session WHAT YOU LEAVE BEHIND - A graph of how far up the levels you have climbed - The hours you tend to practise, and total time - A calendar showing which days you played WHERE YOU STAND - Connect Game Center to see your rank in the world - Today, this week, and all time - Ranks are free for everyone INSIGHTS - Once enough sessions pile up, the app names a pattern you would not notice yourself - Accuracy runs higher on mornings; a level you lost tends to return after a rest day - Differences between levels are factored out, so moving up alone is never called "doing well" - Available on devices with Apple Intelligence, processed entirely on device MAKE IT YOURS - Set the number of questions and the time limit - Choose a starting level, up to the highest you have reached - Three colour themes - iPhone and iPad 1 5 minutes a day is enough to start.
