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 call

The clearest difference is update cadence: Cartesian graph coordinates at every 4 days against Quick Graph's every 5 months. Cartesian graph coordinates also leads on rating (5.0 vs 4.6) and monetization model (free vs free with in-app purchases). Quick Graph's advantage is ratings volume (425 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Cartesian graph coordinates holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Quick Graph has 425 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 94% of Quick Graph's written reviews are positive against 100% of Cartesian graph coordinates's.

UpkeepUpdate frequency

Quick Graph ships an update every 5 months, Cartesian graph coordinates every 4 days. The most recent releases landed on November 10, 2026 and November 3, 2026 respectively.
