Math isn't talent. It's practice.
One problem at a time, 3 minutes a day. A game-style app that turns the formulas you know into answers you see at a glance.

Tap the right expression or type a number. No long write-ups. Repeat the same pattern until your hands move on their own.
Beyond the main map, the Advanced course collects harder integrals. Solve on paper, then type your final answer as an expression. Hints start from the idea and go one step at a time, and every solution shows each step. Over 100 problems.
28 ranks and 571 stages on a single path. Start with basic derivatives, finish at exam level. Clear stages five problems at a time, beat each rank-up challenge, and skip ahead if you already know the material.
Every day you practice adds to your streak. Miss a day and a candle or a comeback challenge gets you back on track. Bon, your space-dog buddy, is waiting for you every day.

Follow friends and see how far they have come. A weekly XP leaderboard makes it easier to keep going than doing it alone.
Drag to spin. Tap a planet below to switch.
Spend the star sand you earn from stages on the gacha. Spin each planet you get with your finger and see it from every side.
From basic derivatives to integration by parts. Each topic gets one page with the formula, the key idea, and worked examples with answers. No app needed to read them.
Slope of a line, Function notation f(x) and substitution, Equation of a line, y=a(x−p)+q and 9 more
Average rate of change, Shrinking the interval (h→0), Difference quotient (and why you cannot divide by 0) and 11 more
Antiderivatives (the reverse of differentiation), The formula for ∫xⁿ dx, Constant multiples, sums and differences (polynomials) and 11 more
Limits of sequences, Infinite geometric series, Graphs of rational functions and 28 more
Integrals of trigonometric functions, Integrals of exponential functions, ∫1/x dx = log|x| + C and 11 more
Class moves fast and the formulas keep piling up. Build the basic patterns in order, a little every day.
AP, A-level, or university entrance. You know the method but run out of time. Make the computation a reflex so you can spend time on the reasoning.
Practice the same pattern until you recognize it on sight.
Every stage and every rank is free. Derivon Super removes ads and gives you unlimited stamina.
