Calcula is a powerful scientific calculator that combines classic RPN stack workflow with a full Algebraic (ALG) mode in one app.
Designed for advanced users, engineers, students, and technical professionals, Calcula lets you choose the input style you prefer, then move seamlessly between both worlds.
Two calculation modes, one engine
- RPN mode for fast stack-based operation
- ALG mode with scientific keypad and direct expression input
- Instant switch between modes from the main interface
Advanced algebraic input
- Scientific ALG keypad with prefix actions (`f/g`)
- Keyboard or keypad entry
- Live rendered math preview with pan and pinch zoom
- Build, inspect, and refine long expressions comfortably
Rich math objects
- Real and complex numbers (Cartesian/Polar behavior)
- Fractions, vectors, and matrices
- Matrix/vector operations including products, transpose, determinant, inverse, dot and cross products
Units, constants, and formatting
- Integrated units workflow in expressions
- Access to constants database in ALG flow
- Shared global number formatting between RPN and ALG
Functions and persistence
- Define and edit functions from both RPN and ALG workflows
- Coherent shared function database
- Draft and editing improvements for smoother continuity
Statistics and scientific tools
- Shared statistics memory across RPN and ALG
- Statistical operations and previews integrated into ALG workflow
- Extended scientific function coverage with ongoing expansion
Calcula is built for real technical work: precision, depth, and flexible interaction without sacrificing speed.
Quoi de neuf dans la dernière version ?
Calcula 2.5 is a major upgrade focused on hybrid scientific workflows.
New true dual-mode experience: RPN and Algebraic (ALG) now work as equal primary modes.
New ALG scientific keypad with dynamic f/g prefixes (plus HYP and SP layers) for faster advanced entry.
Live rendered math preview with pinch/drag navigation and automatic fit for long expressions.
Full support for complex numbers, fractions, vectors, and matrices in ALG workflows.
Expanded linear algebra tools in ALG: transpose, determinant, inverse, scalar/dot/vector products, and matrix operations.
Improved token interoperability: expression-based values remain editable and compatible across stack operations.
Shared global behavior between RPN and ALG for formatting, units, constants, memory, and statistics.
Better stats and memo integration in ALG, including operational shortcuts and reporting.
Function workflow improvements: create/edit/save functions from ALG with bidirectional compatibility with RPN function tools.
New bundled in-app User Guide available from SYS (works offline).
