CalcEditor

CalcEditor is a scientific calculator built around a structured, visual math editor — expressions display in natural mathematical notation, not as a flat line of characters. Scientific & Advanced calculator Trigonometric functions, logarithms, powers, roots, and factorial, plus a full Advanced toolset: graphing, matrices, vectors, complex numbers, equation solving (including systems of equations), derivatives, integrals, a programming/number-base mode, and coordinate conversion — all within the same structured editor. On-device text recognition (OCR) Point your camera at a printed mathematical expression. Recognized, compatible results convert directly into the visual editor, ready to solve — processed entirely on your device, nothing uploaded. Local history, undo & redo Every calculation is saved on your device so you can browse, recall, and reuse past expressions — never uploaded anywhere. Undo and redo let you step back and forward through your edits as you build an expression. Health & science tools BMI and BMR calculators, unit conversion, and area calculations for study and everyday use. Results are educational estimates, not medical advice. Statistics & probability Descriptive statistics, a one-sample t-test, and sample-size estimation to help with coursework and data analysis. 5 customizable themes Choose from Graphite, Porcelain, Midnight, Forest, and Glacier.
