A new way to study with Qedra. - Build derivatives, integrals and limits with guided fields. Enter matrices in a grid and check the preview before solving. - Save problems into course notebooks with your own notes, labels and a marker for topics to revisit. Reopen each problem with its original notation settings. - Practise five topics with hints and solutions revealed one step at a time. - Qedra Pro adds more course notebooks, additional practice variations, and formatted solution PDFs that include assumptions and verification. - Existing notebooks remain readable and editable after Pro ends.

Qedra now speaks your language. The whole app is translated — not just the buttons, but the mathematics itself. Every derivation step, every rule name, every assumption and every honest refusal is now written in your language, because a step-by-step solver whose steps you cannot read is not a solver. ALSO IN THIS VERSION - Decimal comma. Type 1,5 and Qedra reads one and a half, following your region's convention instead of insisting on a point. - Dynamic Type support. Interface text follows your preferred text size, and wide mathematics scrolls horizontally. - Higher contrast throughout, and the mathematics keyboard now reads correctly in right-to-left layouts while the equations stay left to right, where they belong. - Corrections in the engine: several derivations that reached the right answer by a step that did not hold in every case now say what they assumed, or take the route that does.
