WHY BRILLIANT WORKS - One-on-one learning for all Private tutoring is the most effective way to learn, but it’s expensive, hard to schedule, and out of reach for most families. Brilliant’s tutor works with you one-on-one, every single day, for a fraction of the cost. No scheduling. No waiting. Just learning. - Like someone sitting next to you Brilliant’s tutor can see what’s on your screen and react in real time, from highlighting parts of a problem to creating visualizations that bring hard concepts to life. - Expert-crafted curriculum Every course is crafted by our team of human experts from top institutions around the world. And with new and updated courses added every month, there’s always something new to explore. - Learning that adapts to you Brilliant’s tutor personalizes your experience in real time, adjusting to your skill level, filling gaps before they become problems, and helping you build confidence as you go. - Build true problem-solving skills Brilliant doesn’t give you answers. It guides you through problems and to your own a-ha moments. So while you’re learning, you’re also building critical thinking and analytical skills – and having fun. WHAT PEOPLE ARE SAYING “Koji doesn’t judge. It feels like talking to the most patient teacher.” — Alan “Going through a lesson with Koji is more active, interactive, and guided than traditional learning.” — Lory “She read the problem out loud and figured it out on her own — ‘Oh! I know! Never mind, Mom, I got it!’ I'm seeing those breakthroughs more often.” — Arianne Send feedback to ios@brilliant.org.

Stoichiometric equations
Read full descriptionHide full description
Stoichiometric Equation balances chemical reaction equations for you — no trial and error, no guessing. Enter the reactants and the products, tap Balance equation, and the app returns the stoichiometric coefficients as the smallest set of whole numbers. Balancing an equation means making sure that the same number of atoms of every element appears on both sides. For a reaction such as 2Na + Cl₂ = 2NaCl you can still do that in your head. For e.g 3As₂S₃ + 28HNO₃ + 4H₂O = 6H₃AsO₄ + 9H₂SO₄ + 28NO, trial and error quickly stops being practical. That is exactly where this app takes over. HOW IT WORKS Instead of guessing, the app treats the equation the way a mathematician would: every unknown coefficient becomes a variable, the atom counts for each element become one linear equation, and the resulting system is solved with Gaussian elimination. The coefficient matrix is transformed into reduced row echelon form and the solution is scaled to the smallest whole-number coefficients. The complete derivation is included in the app, step by step, with a fully worked example — so you can not only get the answer, but also understand how it is found. FEATURES • Balances simple reactions and long, complex equations alike • Nested grouping with parentheses ( ), square brackets [ ] and braces { } • More than 90 chemical elements, written with the international IUPAC symbols • Results in the smallest whole-number coefficients • Clear, formatted output: proper subscripts, highlighted coefficients, monospaced layout • Long results are wrapped automatically to fit your screen • Precise error messages — unbalanced brackets, unknown element symbol, non-balanceable equation and more, each named instead of a vague "invalid input" • A collection of ready-made example equations: tap one and it is solved instantly • Built-in theory section explaining the mathematics behind the solver • German and English interface, chosen automatically from your device language • Optimised for iPhone and iPad, in portrait and landscape BUILT-IN EXAMPLES The app ships with examples ranging from textbook reactions to equations that would take a very long time by hand,

Verdict
The clearest difference is in-app purchases: Stoichiometric equations at none against Brilliant's 19. Stoichiometric equations also leads on ads (none vs shown) and device support (4 vs 2). Brilliant's advantage is update cadence (weekly vs every 3 months) and chart position (#82 vs unranked). On price there is nothing between them.
