## What is Qedra?

Work through supported calculus, algebra and matrix problems offline, with exact answers and steps you can follow.

Qedra brings university mathematics to your iPhone and iPad. Calculations run on your device, even in airplane mode. No account is needed.

BUILD THE PROBLEM YOU MEAN

Enter derivatives, integrals and limits with guided fields. Use a matrix grid for determinants, inverses, row reduction, rank and eigenvalues. Check the live preview before solving, or type directly with the mathematics keyboard.

UNDERSTAND THE WORKING

Open a step to read its named rule, explanation and assumptions. Fractions stay exact. Where a verification check is available, Qedra shows its result and limitations. Some inputs remain symbolic or receive a method-limit explanation.

KEEP YOUR REVISION NOTES

Save useful problems in a course notebook, add your own notes and labels, search your collection and mark topics to revisit. Saved problems keep their original notation, operation and real or complex setting. Notebooks stay on this device.

PRACTISE WITH HINTS

Try a problem yourself, ask for a hint and reveal the solution one step at a time. Supported practice topics include power-rule derivatives, polynomial integrals, integration by parts, 2 × 2 determinants and linear equations. Scratch work is not automatically graded.

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

Decimal-comma input, notation settings, a rule reference library and translated explanations help you follow the mathematics in your own way.

START WITH THE FREE TIER

Get unlimited answers, three full worked solutions per day, the most recent 100 unpinned history entries, one course notebook and one practice example per topic. Pinned history stays until you delete it. Text sharing and copying answers as LaTeX are included. The free tier can show a banner on the Solve screen.

QEDRA PRO

Pro adds unlimited worked solutions and history, more course notebooks, additional practice variations, formatted solution PDF export and no ads. PDFs include the answer, working, assumptions and verification. Existing notebooks remain readable and editable if Pro ends.

## Version history (last 5 releases)

### 1.3.1 — 2026-10-22

Clearer Pro billing details and more reliable subscription management. Membership now refreshes after plan changes, restores and payment recovery.

### 1.3 — 2026-10-12

- Start solving with clearer examples and guided entry.
- Continue studying from the problems you marked to revisit.
- Compare Pro benefits and choose a monthly, annual or Lifetime plan more easily.
- Membership details show available purchase dates and localized prices more clearly.
- Improved reliability for exact arithmetic and domain-sensitive calculations.

### 1.2 — 2026-09-29

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.

### 1.1 — 2026-09-10

Bigger type, better contrast, and mathematics VoiceOver can read.

Dynamic Type support. Interface text follows your preferred text size, and wide mathematics scrolls horizontally. VoiceOver describes mathematical structure, including fractions and powers.

ALSO IN THIS VERSION

- Your decimal separator. Qedra takes it from your region now instead of being fixed to a point, with a switch in Settings for when your coursework uses the other one.
- 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.
- More languages for both the interface and the derivation prose. A coursemate who does not read English can use Qedra now, and so can you with your device set to another language. Arabic and Hebrew mirror the interface; the equations stay left to right, where they belong.

### 1.0 — 2026-08-31

No release notes.
