Numerical Solver is a mobile-first numerical mathematics tool for solving equations, differential equations, and analyzing mathematical functions. Solve equations numerically Solve algebraic equations with one or more variables, including nonlinear equations and systems of equations. • Solve equations numerically • Solve nonlinear equations and systems • Find real and complex solutions • Evaluate solutions at specific values • Solve equations with a single variable for free, with no limits Solve ordinary differential equations Numerical Solver supports linear and nonlinear ordinary differential equations, including initial value problems (IVPs), boundary value problems (BVPs), and systems of ODEs with multiple dependent variables. • Solve initial value problems • Solve boundary value problems • Solve linear and nonlinear ODEs • Solve systems of ODEs • Compute the solution at a given value of x • Plot numerical solutions Visualize ODE systems For systems of ODEs, choose which variables to plot against each other and explore relationships and trajectories within the system. For example, you can solve the Lorenz system and visualize its characteristic trajectories through different combinations of variables. Differentiate equations Differentiate equations with respect to x or y and evaluate the derivative at specific values. • Differentiate equations with respect to x or y • Evaluate derivatives at given x and y values • Work with multivariable expressions Plot functions and data Plot mathematical functions or visualize a list of x,y data points. • Plot functions • Plot lists of data • Explore numerical results visually Numerical computing on the go Numerical Solver is designed to give you practical numerical tools wherever you are, without requiring an internet connection. Use it for mathematics, engineering, science, education, or whenever you need to solve and visualize numerical problems. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is in-app purchases: Hajj Guide at none against Numerical Solver's 3. Hajj Guide also leads on iOS requirement (15.1 vs 17.6). Numerical Solver's advantage is update cadence (monthly vs every 11 months). On price, ads and device support there is nothing between them.
