Understand the steps. Keep what you learn. Come back ready to practise. Qedra solves supported university mathematics on your iPhone or iPad, with named rules, worked explanations and exact arithmetic. Calculations run on your device, even in airplane mode. BUILD THE PROBLEM YOU MEAN Guided fields help you enter derivatives, definite and indefinite integrals, and limits. A matrix grid makes it easier to enter determinants, inverses, row reduction, rank and eigenvalue problems. Check the live preview before solving, or use the mathematics keyboard for direct input. FOLLOW THE REASONING See the answer, then work through the derivation. Open a step to read its explanation and assumptions. Where a verification check is available, Qedra shows its result and limitations. Unsupported problems receive an explanation instead of an invented solution. MAKE YOUR OWN REVISION NOTES Save problems in a course notebook. Add notes and labels, search your collection, and mark problems to revisit. Saved problems retain their original notation, operation and real or complex setting. Notebooks stay on this device and are separate from recent history. PRACTISE ONE STEP AT A TIME Try a problem yourself, ask for a hint, then reveal the solution gradually. Practice topics include power-rule derivatives, polynomial integrals, integration by parts, 2 × 2 determinants and linear equations. Your scratch work is not automatically graded. EXPORT THE COMPLETE SOLUTION Qedra Pro exports formatted PDFs with the answer, working, assumptions and verification. Text sharing and copying answers as LaTeX remain available without Pro. MATHEMATICS FOR YOUR COURSEWORK - Algebra, equations and inequalities - Limits, derivatives and supported integrals - Partial derivatives, multiple integrals and vector calculus - Exact determinants, inverses, row reduction, rank and eigenvalues - Discrete mathematics, probability and statistics - Complex arithmetic Fractions stay exact. Decimal-comma input, notation settings, a rule reference library and translated explanations help you follow the mathematics in your own way. NO ACCOUNT NEEDED Your problems and notebook notes are not uploaded to a Qedra server. Calculations work offline. The free tier can show a banner on the Solve screen; your mathematics is not sent to the advertising partner. Pro removes ads. QEDRA PRO Free includes unlimited answers, three full worked solutions a day, the most recent 100 history entries, one course notebook and one practice example per topic. Pro adds unlimited worked solutions and history, more course notebooks, additional practice variations, PDF export and no ads. Existing notebooks remain readable and editable if Pro ends. - Monthly: $2.99 per month - Yearly: $14.99; 3-day free trial if eligible - Lifetime: $49.99 once, never renews Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the current period ends.
