About this app

A Calc — every calculator function you need for A-level, in one app.

Built specifically for A-level maths, further maths, and science students who are tired of switching between apps (or hunting for a physical calculator) mid-revision.

SCIENTIFIC CALCULATOR
- Trig functions in degrees, radians, or gradians
- Logs (log, ln, 10^x, e^x), powers, roots, and factorials
- nCr / nPr for combinatorics
- Fraction mode — see exact answers, not just decimals
- Memory and Ans, just like your exam calculator
- Full calculation history

GRAPHING
- Plot multiple y = f(x) curves at once
- Pinch to zoom, drag to pan
- See exactly how a function behaves — perfect for checking coursework or visualizing past-paper questions

EQUATION SOLVER
- Quadratics — real, repeated, or complex roots, plus the turning point
- Linear systems — 2 or 3 unknowns, solved instantly

STATISTICS
- Mean, median, standard deviation (population and sample)
- Two-variable linear regression with correlation coefficient

MATRICES
- 2×2 and 3×3 — determinant, inverse, addition, subtraction, multiplication

Two visual styles included: a clean modern layout, or a classic hardware-calculator look if that's what you're used to — switch anytime from the top bar.

No unnecessary permissions, no clutter — just the calculator functions an A-level syllabus actually requires.
