Polynomial vs Calcu
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Polynomial
Read full descriptionHide full description
The PolynomialSolver is carefully designed to be a simple and elegant app. Easy to use, easy to understand, simple and effective It solves (finds all the roots) polynomials of any order (any degree). Roots can be real, complex or combination of both. No problem. This app has you covered. To find all the solutions, it uses Aberth Ehrlich algorithm for higher order polynomials. The polynomial is beautifully presented in mathematical format. You can also solve multiple polynomials at once. You can also share the polynomial and its solution. Perform the polynomial division to find the quotient and remainder. This app also plots beautiful graph of the polynomial(s) so that you can visualize the solution in the graph. The graph can be shared with other or it can be saved locally on your device. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning to solve these kind of equations. There is also a Study page to help you with learning some important polynomial concepts. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
Calcu

Calcu-Logarithm performs calculations and helps user understand logarithms on advanced level: 1. Solves equation "y = log_a(x)” for “y”, “x”, and “a”, with relevant graphs. 2. Explains and illustrates how to compute log_e (x) from Taylor series. 3. Explains and illustrates how to compute log_10 (x) digit by digit (based on M.Goldberg algorithm). 4. Explains and provides proof of log_e definition as the integral of x inverse. 5. Simplifies logarithmic expressions and solves logarithmic equations with polynomials of up to 20th degree. 6. Includes virtual slide rule for multiplication and division. 7. Calculates, explains, and graphs logarithms of complex numbers.

Verdict
The clearest difference is ads: Calcu at none against Polynomial's shown. Calcu also leads on update cadence (every 3 days vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
