Slopes is an interactive environment for exploring graphical solutions to ordinary differential equations. Slopes consists of six activities with preloaded examples to get you started and the ability to input your own content. "Slopefields" and “Phase Planes” both plot vector fields and solutions corresponding to multiple initial conditions. “Systems” dynamically solves systems of up to six equations. “Oscillations” solves second-order constant coefficient equations and animates the corresponding spring-mass system or RLC circuit. “Methods” constructs numerical approximations of a single ordinary differential equation using Euler’s method as well as Second and Fourth Order Runge-Kutta methods. "Bifurcations" creates a bifurcation diagram and shows the stability of equilibrium points. Slopes is a playground for ODEs. You can use it for homework, in-class activities or a new research project.

Graph points to draw unique pictures - Cartesian plane drawing with coordinates is a math-based game that teaches children basic math and essential geometry skills! Coordinate Plane game teaches you to solve real mathematical problems by correctly graphing points together. Cartesian plane named after mathematician Rene Descartes. He created a system of plane graph coordinates, that joins each point on the plane with a number. Coordinates and the Cartesian Plane is an important topic in any school curriculum and it’s required to be taught to all primary school kids. It’s an easy enough topic for little kids to grasp, especially when paired with simple but fun art drawing challenges. After all, joining points together creates pictures, and add to that math coordinates and you’re not only learning math, you're also being an artist! Learn how points are written in (x, y), how they are oriented to the axes, what is a positive and negative directions, how to read coordinates and what it means to join them together. This cool math game will make children learn in a fun and engaging way! Our game is: Completely FREE Simple - locate the points in the cartesian plane and join them to draw millions of pictures! Guarantees Brain fitness, promotes creativity, teaches logical thinking and connects visual aspects with theory! Provides a real IQ boost. Has 3 difficulty levels, with each one having hundreds of different exercises and challenges. Has clean design reminiscent of old-school notepads and simple but engaging graphics. Introduces active learning experience. Challenges kid’s imagination. Learn plane coordinates graph system while playing our fun, free math game!

Verdict
The clearest difference is in-app purchases: Slopes at none against Cartesian graph coordinates's 1. Slopes also leads on ratings volume (41 vs 1). Cartesian graph coordinates's advantage is update cadence (every 4 days vs every 2 months) and iOS requirement (12.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Cartesian graph coordinates sells 1 one-off in-app purchase. Slopes asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.9 for Slopes against 5.0 for Cartesian graph coordinates. That said, the two scores are not equally well evidenced: Slopes has 41 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Slopes ships an update every 2 months, Cartesian graph coordinates every 4 days. The most recent releases landed on September 19, 2026 and September 17, 2026 respectively.
