FliFlopMath is built for one thing: getting you to solve math in your head, without pen, paper, or a calculator. Open the app, pick a topic, and a question shows up. You answer with the one thing you actually have on you — your brain.

There are nine topics to choose from: addition & subtraction, multiplication, division, exponents, factorials, derivative rules, integral rules, trigonometry, and logarithms. Stick to one topic, or pick "Mixed" and get a random blend of everything — a solid way to prepare for an exam where you never know what's coming next.

Every topic has easy, medium, and hard tiers. Easy is a warm-up with simple operations; hard gets genuinely challenging, with chain-rule derivatives, implicit differentiation, logarithmic differentiation, and integral rules that go well past basic arithmetic. This isn't just a times-table drill — you can push it as far as calculus if you want to.

You decide how long a session is: enter any number from 1 to 100 questions and go. For questions that need a typed expression (like derivatives or integrals), a small symbol keypad appears on screen so you can tap in sin, cos, square roots, π, and similar symbols instead of hunting for them on your keyboard.

Once a session ends, you don't just see a correct/wrong count — tap "See Solutions" to review every question from that session, side by side with your answer and the correct one. It's an easy way to spot exactly where you went wrong instead of just seeing a final score. There's also a stats card on the home screen you can tap for a breakdown of your accuracy by difficulty level.

The app works in both English and Turkish, with light and dark themes. There's no account to create, no email or phone number to hand over — we don't collect any personal information. The only thing kept is your correct/wrong stats, stored locally on your own device.

FliFlopMath is an independent, free app. If you like it, there's an optional donation section on the home screen, and you can choose to watch a short ad to support development — but it's entirely optional and never required to use the app.

In short: FliFlopMath is a small, no-friction mental math workout — something you can open on the bus, between classes, or in a five-minute break, just to check how fast your brain is running today.
