# PocketCAS vs Linear Equations Calculator

The clearest difference is rating: PocketCAS at 4.6 against Linear Equations Calculator's 4.1. PocketCAS also leads on monetization model (free vs free with in-app purchases) and review sentiment (91% vs 76%). Linear Equations Calculator's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PocketCAS sells 1 one-off in-app purchase and Linear Equations Calculator sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

PocketCAS holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: PocketCAS has 205 ratings behind it against 28, 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 76% of Linear Equations Calculator's.

PocketCAS ships an update every 3 months, Linear Equations Calculator every 3 weeks. The most recent releases landed on November 10, 2026 and November 11, 2026 respectively.
