Galileo
Read full descriptionHide full description
The goal with Galileo is to explain with simple words, the complex yet beautiful physics that is inside everything in our world. Contents are presented in small articles, written with a simple language. The articles covers various topics from mechanics to nuclear physics. Articles includes images, animations, 3D models and sometimes a little equation. Get a better understanding of physics with Augmented Reality! Place experiments and animated 3D models on you table and explore them by moving around.
ODE

The ODESolverIntegrator is a simple but elegant app to find the integral of ODEs. You can solve (find the integral of) nonlinear ODEs. You can reduce the higher order ODE to a set of first order ODEs. You can solve (find the integral of) linear ODEs in the form of αΊ = Ax + Bu; y = Cx + Du. This app uses Runge-Kutta 4th order algorithm to solve the ODEs. Once the ODEs are solved, a beautiful interactive graph for each ODE's is created that you can share with other or save it locally. The reduced ODE's equations are presented beautifully in the math-equation format. You can compute definite integral (single, double, tripple). It uses the midpoint method. 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 app also has a Study page to help you learn important integration rules like, power rule, product rule, ect. This app is perfect for students learning calculus. Sharpen you brain by using this app and learning about the calculus. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

Verdict
The clearest difference is price: Galileo at Free against ODE's $1.99. ODE's advantage is update cadence (monthly vs every 4 months) and iOS requirement (15.1 vs 17.6). On ads, in-app purchases and device support there is nothing between them.
