# PocketCAS vs Cartesian graph coordinates

The clearest difference is update cadence: Cartesian graph coordinates at every 4 days against PocketCAS's every 3 months. Cartesian graph coordinates also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 91%). PocketCAS's advantage is ratings volume (204 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PocketCAS sells 1 one-off in-app purchase and Cartesian graph coordinates sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Cartesian graph coordinates holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: PocketCAS has 204 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 91% of PocketCAS's written reviews are positive against 100% of Cartesian graph coordinates's.

PocketCAS ships an update every 3 months, Cartesian graph coordinates every 4 days. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
