About this app

MathRise is the competitive way to get faster at mental math.

Step into the arena and face real opponents in fast, 10-problem duels. Same problems, same clock — the fastest correct answers win. Every duel moves your Elo rating, just like chess. Climb the tiers from Rookie to Grandmaster and prove you're the sharpest calculator in the world.

NEW: THE SHOP & KEYPADS
Earn coins as you play and spend them in the shop: neon, mechanical, ink, retro-LCD keypads and more, unlocked level by level. Your keypad, your style.

FRIENDS & FRIEND CHALLENGES
- Add friends by username, follow their stats and rank.
- Challenge a friend in one tap: the challenge lands right in their app, with problems calibrated halfway between your two levels. They beat your time? Rematch in one tap.
- Challenge anyone with a link or a code: same problem set, fastest wins — with a shareable score card.

LIVE GROUP SESSIONS
Open a room and show the code: your friends — or a whole classroom — join with just a first name, no account needed. Everyone races the same problem set, podium at the finish, and one tap starts the next round.

WHY MATHRISE
- Ranked duels: head-to-head mental math races with a true Elo rating. No luck, pure skill.
- The Daily Challenge: one try a day, the same 10 problems for the whole planet. Where do you land on today's board?
- Global & national leaderboards: see where you stand in your country and worldwide.
- Daily quests & coins: three fresh goals every day — rewards pay out automatically.
- Streak & streak freeze: play every day, and protect your run when life happens.
- Win streaks: chain victories for up to double XP.
- Practice mode: drill addition, subtraction, multiplication, division, times tables, squares, percentages, fractions.
- Warm-up: a quick 90-second arithmetic sprint to get your brain firing.

BUILT FOR SPEED
No clutter, no childish gimmicks — a clean, dark, focused arena for teens and adults who want to get genuinely fast at mental arithmetic.

Whether you're sharpening up for school or exams, keeping your mind quick, or you just love the thrill of a photo finish, MathRise turns mental math into a sport.


FOR TEACHERS
Run it as a class game: create a session, write the 6-letter code on the board, and up to 100 students race the same problems — no student accounts needed. Details: mathrise.io/classroom

Duel. Calculate. Rise.

What’s new

The daily challenge has a screen of its own: a calendar of every day you showed up, your best rank, your podiums — and any past day's board. Ten problems, the same for everyone, one attempt a day.

Also: the result screen fits on one screen, tap your opponent to see their card and add them as a friend, the leaderboard shows your place from your first duel, and winning a placement duel can no longer cost you Elo.
