About this app

The Calculator provides a comprehensive set of tools for algebra, calculus, trigonometry, statistics, and more. Designed for students, engineers, educators, and math enthusiasts, it offers a powerful CAS programming engine (Symja) and an intuitive interface for everyday calculations and advanced problem-solving.

ALGEBRA

1. Computer science functions
2. Solve equations
3. Solve systems of equations
4. Graph functions
5. Cartesian geometry
6. Unit conversions
7. Simplify algebraic expressions
8. Polynomial factorization
9. Binomial expansion (Newton's formula)
10. Matrix calculations

CALCULUS

1. Derivatives
2. Antiderivatives
3. Definite integrals
4. Limits of sequences and functions

TRIGONOMETRY

1. Trigonometric expansion: sin(2x) → 2sin(x)cos(x)
2. Trigonometric reduction: 2sin(x)cos(x) → sin(2x)
3. Convert trigonometric and hyperbolic functions to exponential form

STATISTICS & COMBINATORICS

1. Combinations
2. Permutations

ADDITIONAL FEATURES

1. Prime factorization
2. Modulo calculations
3. Catalan numbers
4. Fibonacci numbers

The calculator supports two computation modes:

- Decimal mode: e.g., 0.12312312323
- Fraction mode: precise symbolic results, e.g., 9^99999

This combination of CAS programming and extensive math functions makes the app a reliable tool for learning, teaching, and technical work.

I have not used all of the programmable functionality, but I'm happy to see it's available. [Edit] It took me _way_ too long to figure out the blue and red additional functions, etc. can be reached by simply pressing the button longer. This is not a criticism, but a confession. I was unable to find any documentation about how to use the phone screen interface, but it never dawned on me that it worked like every other phone app. 😜

Edit: New version is much worse, not a fan of the new UI, the equals button doesn't work the same, and history is broken. It's been 4 months and this hasn't been fixed... Time to move on :/ I was just looking for a simple calculator with a clean ui and a cursor so I could edit mistakes without deleting everything. This calculator does everything I wanted and so much more! It's an absolutely fantastic app. Way better than every other calculator, even the paid ones.

This calculator has tons of features, but it drives me crazy that pressing '=' does nothing for basic calculations. If you want to start from the calculated value you have to clear and then input ANS. It seems like a small thing, but it makes quick calculations inconvenient since otherwise you have to put the entire expression with parentheses to enforce the correct OOO.
