A personal trainer for the mind: fourteen short exercises across memory, numbers, focus and logic, one score that makes everything comparable, and a Challenge between two nearby phones. Runs entirely on the device, with no account and no network. HOW IT WORKS The screen is split in four by its diagonals, one colour per area. Tap a sector, pick an exercise and a difficulty, play for a minute. At the end you get a score from 0 to 1000, the same scale for every exercise: a good Pairs round is worth as much as a good arithmetic round. Statistics show an overall index and one per area, day by day. THE FOUR AREAS • Memory: colour sequence, grid, digit span, Pairs with playing cards, animals, food or objects. • Numbers: quick maths, estimation at a glance, what comes next, and the till: give the exact change by catching coins and notes in nine currencies. • Focus: colour or word (Stroop effect), reflexes, the odd one out. • Logic: matrices, anagrams, analogies. WHAT SETS IT APART • The till: an exercise found nowhere else, born from someone who really stands behind a counter. • Several players on one phone, each with their own statistics, records and certificates. • The certificate of the month: your personal best on a sheet to share or print. • The player card: take your results to another phone in a file. • Age adjusts the games: timings and the yardstick for reflexes change with the years. • Six Home themes, including a marquetry of four woods. • Fifteen languages; anagrams and analogies rewritten, not translated, in five. REAL PRIVACY No account, no data collection, no ads. History is a file on the phone. The only permission requested is local network, and only for the Challenge. FREE AND PRO All fourteen exercises are open, at every difficulty. Free: six sessions a day and the last seven days of history.
