# Slopes vs Cartesian graph coordinates

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.

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 October 6, 2026 and September 17, 2026 respectively.
