A math formula trainer with gothic aesthetics and iron logic. Know the formula — own the tool. Don't know it — lose where you could have won. Algebrion is built for those who want formulas memorised, not Googled before an exam.
From squares and logarithms to integrals, limits, and complex numbers. Everything in one place.
Flashcards, theory reference, step-by-step problems, quiz, and manual input. Each mode has its own flow.
Every mode lets you drill a single topic — only the formulas you need right now.
No account, no internet, no ads. Everything works on the device from the first launch.
Full interface in Russian, Ukrainian, English, and Spanish.
Gothic dark mode by default. Switch to light at any time from settings.
Each mode trains a different part of your memory. Use them in sequence or jump to what you need.
Flip through formulas like a deck of cards. Tap to reveal the right-hand side. Simple and effective.
A complete reference with formula names, hints, and examples. For understanding, not just memorising.
Real examples with value substitution. Solve it, then check the step-by-step solution.
Choose the correct right-hand side from four options. The score does not lie.
Type the formula yourself from scratch. The most honest mode — no hints, no options.
From secondary school algebra to university calculus — all covered and filterable in every mode.
Free for iOS. No account required. No ads. Works fully offline.

Everything you need to get started and make the most of Algebrion.
Open Algebrion. The intro splash plays once — after that you land on the Flashcards screen. Swipe left or right, or tap the bottom tabs, to switch between the five modes.
Tap the compass icon in the top-left corner to open Settings. Choose your language, theme, and font size.
Recommended start: spend a few minutes on Theory to get familiar with the formulas, then move to Flashcards, then Quiz.
Each card shows the left-hand side of a formula. Tap the card to flip it and reveal the right-hand side.
Use the navigation arrows to move forward or backward through the deck. The counter in the top-right shows your position.
Filter by topic: use the horizontal strip at the top to restrict the deck to a single topic — e.g. only Integrals or only Trigonometry.
A scrollable reference of all formulas, grouped by topic. Each entry shows the full formula, its name, a usage hint, and a worked example.
Use the topic filter strip to jump directly to the section you need without scrolling.
The app picks a formula and generates a numeric example by substituting random values. Your task is to compute the result using the formula.
Use it actively: try to solve in your head or on paper before revealing the solution. The step-by-step exists for checking, not skipping.
A formula's left-hand side is shown. Choose the correct right-hand side from four options. One is correct; three are plausible distractors drawn from nearby formulas.
Retry the same topic: from the score screen, tap Try again to repeat the same filtered set in a new random order.
The left-hand side of a formula is shown. Type the right-hand side in the text field. A quick-symbol bar appears above the keyboard with common characters: ², ³, −, ·, parentheses, and variables.
Most honest mode: there are no options to pick from — you must recall the formula from memory. Use this after mastering Quiz.
All five modes have a horizontal scrollable strip at the top with a pill for each topic plus All. Tap any pill to restrict that mode to one topic only.
Switching topics resets the current session (score, position, and order) for that mode. The filter is independent per mode — Quiz can be on Integrals while Flashcards stays on All.
Tap the compass icon in the top-left corner of any screen.
Settings are saved locally and restored on next launch.
Quiz and Input modes track your score live. The counter in the top-right corner shows the number of correct answers in the current session.
At the end of a session (all formulas answered), a score screen shows:
