Verdict
The clearest difference is review sentiment: Pascal at 68% against Calculator's 0%. Calculator's advantage is price (Free vs $2.99) and rating (4.4 vs 4.0). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.

Calculator is free to download; Pascal costs $2.99 up front. Pascal sells 3 one-off in-app purchases and Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Calculator holds the better App Store score, 4.4 against 4.0. Both are backed by a comparable volume of ratings — 23 and 10 respectively. Written reviews complicate that: 68% of Pascal's written reviews are positive against 0% of Calculator's, so the app with the better star average is not the one people write more warmly about.
Pascal ships an update every 2 weeks, Calculator every 4 days. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
