Primality vs Universal Calculator (beans)
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Primality
This app determines if a given integer is prime or provides its prime factors. It also calculates the ordinal position of prime numbers found, up to a certain limit.
- Primality testing
- Prime factorization
- Prime ordinality calculation
- Large integer support (up to 999,999,999,999)
- Clean and simple interface

The Primality App has a clean and simple, yet powerful, function: Given any integer, the app determines either that the given integer is prime or else it provides all prime factors of that integer. Very clean, very simple, focussed. The app operates in the range of 0 - 999,999,999,999. A popular feature of the app is its ability to determine the prime ordinality of each prime found, such as observing that 97 if the 25th prime. (However, this particular feature is available only up to the 100,000th prime, which is 1,299,709.) Requires iOS 13 or higher.

This is the free version of the Universal Calculator app. This version has full access to everything. After 24 hours, you will lose access to turn off one of the sounds and will only be able to use the app if your mobile device is not muted. Other than that, everything else is still fully accessible forever. The Universal Calculator is a scientific graphing calculator that offers a myriad of calculation features which extends beyond most graphing calculators. While it can be used for its standard Calculator and Graphing capabilities, it also calculates: - Polynomial Factorization - Polynomial Multiplication and Division - Integer Factoring - Prime Integer Factoring - A Plethora of Unit Conversions - Matrix Addition, Subtraction, and Dot Product - Matrix Inverse, Transpose, Adjugate, and Cofactor - Matrix Upper Triangle, Lower Triangle, and Diagonalization - Matrix Determinant and Eigenvalues - Triangular Geometry Calculations - SAE to Metric Measurement Conversions - Tips for Bills Enjoy a calculator history capable of storing 100 of your previous calculations. Each history line is selectable, allowing you to insert the equation or answer into your current equation! It also contains 15 common scientific constants for ease of use. For the Graphing inclined, graph in color for up to 10 equations simultaneously and intuitively zoom in and out like you would a photo! You can also calculate their intersections, trace the equations for a finer look at the values, graph an equation equal to y-squared, customize the thickness and color of each equation, and much more! Personalize your Universal Calculator experience in the settings options. The Universal Calculator contains 6 different color themes, 7 different sound options, haptic feedback, and more. Lastly, enjoy peace of mind knowing that the Universal Calculator will never collect your information, and will never contain ads. This is an essential part of this ongoing project which is taken very seriously. If you have any suggestions or find any bugs, please reach out!
