MathRise: Mental Math Duel

Track your progress, duel after duel. Every ranked duel now gets a performance score: your speed against the questions' difficulty, on the Elo scale. Beat your average or your record and the app tells you, and "My progress" draws your curve. Also in this version: • A new look: each mode has its own color, and text stays readable even at large sizes. • Practice adapts to you: it eases off after two misses in a row, climbs back when you're on a roll, and ends with a "To review" list. • Your username can have accents (João, Łukasz, Nguyễn) or be written in Japanese or Korean. • New player? Your first ranked duels are placement duels, then "Placement complete" shows your starting Elo. • Friend challenges and group sessions now count toward XP, streak and quests, and a challenge played from your link shows up in your Duels. • At most one reminder a day, at the time you usually play. • Ads: decline consent and the app no longer asks to track you. • Stability improvements.
