Scientific++ is a scientific calculator which has the following additional functionality compared with most available calculators: - Shows the expression as you enter and keeps a history of your calculations (Swipe up on the screen to reveal the history) - Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations. - Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format. - Capability of calculating permutation, combination, Least Common Multiple (LCM), Greatest Common Divisor (GCD), and prime factorization. - Quadratic and system of two linear equations solver - Rectangular to polar and polar to rectangular coordinate conversion (extremely useful for phasor calculations for electrical engineers) - Common physical constants can be chosen from a list and used in the calculations. - Throws a set of dice (choice of 1 die to 4 dice) - Backspace to delete last digit entered. - The left pane scrolls to reveal more functionality without a need to switch modes. The digits and most common operations are always visible and the less common operations can be revealed by scrolling the left half of the screen. - Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians. - Showing the content of memory on MR button, as long as it fits. - Right Triangle & Rectangle Calculator through in-app purchase. Scientific++ is an ongoing project and we are working on more features and functions to be added to every update of the app. You are going to love the simplicity of the user interface and you will get used to the extra functionality added to this product. Please do not hesitate to contact us for any questions, comments, to report any bugs, or to suggest additional functions you would like to see in the upcoming updates.

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.

Verdict

The call

The clearest difference is rating: Phase Calc at 5.0 against Scientific++'s 4.5. Phase Calc also leads on update cadence (every 6 weeks vs every 6 months) and review sentiment (100% vs 89%). Scientific++'s advantage is ratings volume (61 vs 4) and price ($0.99 vs $1.99). On ads, in-app purchases and device support there is nothing between them.

Scientific++ costs $0.99 and Phase Calc $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Phase Calc holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Scientific++ has 61 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 89% of Scientific++'s written reviews are positive against 100% of Phase Calc's.

UpkeepUpdate frequency

Scientific++ ships an update every 6 months, Phase Calc every 6 weeks. The most recent releases landed on September 24, 2026 and August 1, 2026 respectively.
