About

Is it right? You get about a second. A sum flashes up with an answer. Tap True or False before the fuse burns out. That's the whole game, and it's harder than it sounds. MEET GRUMP The whole screen is Grump's face, and Grump hates it when you're good. Every right answer winds it up: the background heats from cold blue to boiling red, the brows drop, the mouth clenches. Keep a streak going and you hit meltdown. Miss, and it smirks. ONE ENDLESS RUN, THREE LIVES • True or false, so anyone can play from the first tap • A burning fuse that starts under two seconds and shrinks towards one • Three lives, and every 15 in a row wins one back • It ramps up on its own: quick sums, bigger numbers, times tables, then two-step problems THE DAILY 40 The same 40 sums for everyone, every day. One shot. Keep your daily streak going, share your grid without spoiling the answers, and get a reminder at 9am if you want one. CHASE YOUR BEST Game Center leaderboards for your best Endless run and for the Daily. The game tells you exactly how close you came, so "one more go" is never far away. FEELS RIGHT Adaptive sound and music that build with your streak, plus haptics on every answer. FAIR AND FRIENDLY • Free, with no ads • No account needed, and it plays offline • Relaxed timer if you want 60% more time (relaxed runs stay off the leaderboards) • Made for iPhone, iPad and foldable iPhone Great for quick mental math practice, sharpening times tables, or just seeing how fast your brain really is. Angry Math Pro lets you play missed Daily challenges and replay past days, plus unlock the Dusk, Tide and Mono looks with matching app icons. One purchase, yours for good. Archive replays are not ranked and do not change your Daily streak or today’s attempt. Ember, the original look, is always free.
