Phase Calc vs Universal Calculator (beans)

Phase Calc for iOS is an advanced engineering app for most electrical designs, expecially symmetrical component analysis and three-phase power system calculations. Built for students, teachers, technicians, and engineers, it combines a polished mobile experience with a powerful technical workflow for fast, accurate analysis of unbalanced three-phase systems in the field, lab, or classroom. The app performs both phase-to-sequence and sequence-to-phase transformations, with support for inputs in polar and rectangular form. It quickly resolves three unbalanced phase quantities into their positive-, negative-, and zero-sequence components, making it a practical tool for protection studies, fault analysis, system modeling, relay validation, and coursework. More than a single-purpose calculator, Phase Calc is packed with specialized calculators, technical reference libraries, and built-in formulas to support everyday power systems work. Whether you are checking values, reviewing theory, or working through engineering problems more efficiently, the app puts essential tools in one place. Results can be exported instantly, including vector data for plotting and graphical analysis, as well as technical report exports for documentation, review, and sharing. With powerful capabilities in a streamlined interface, Phase Calc delivers a complete mobile toolkit for three-phase analysis on iPhone and iPad.

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!
