# PocketCAS vs GraphMath

The clearest difference is update cadence: GraphMath at fortnightly against PocketCAS's every 3 months. GraphMath also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 91%). PocketCAS's advantage is ratings volume (204 vs 12). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

GraphMath 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 12, 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 GraphMath's.

PocketCAS ships an update every 3 months, GraphMath fortnightly. The most recent releases landed on October 19, 2026 and October 5, 2026 respectively.
