Scientific Calculator Pro

Scientific Calculator is an offline calculator for students, engineering work, and everyday technical math.

The calculator supports natural-language expression entry with rendered fractions, powers, roots, logarithms, trigonometric and hyperbolic functions, complex numbers, and a calculation history. It also includes advanced symbolic integration and derivative tools with live equation preview, so typed expressions can be checked before solving.

Main features:
- Scientific calculator with natural math display
- Symbolic integration and symbolic derivative modes
- Graphing tools
- Matrix, vector, equation, polynomial, and statistics modes
- Formula solver and engineering-style utilities
- Unit conversion and constants
- Local history and settings
- Offline Android WebView app with no analytics SDK and no ads SDK

Symbolic calculus results can depend on domains, discontinuities, branch cuts, constants of integration, and simplification assumptions. Important answers should be verified for the exact problem conditions.

All calculator data is stored locally on the device.
