# Calculator + vs Calculator & AI Math Solver

The clearest difference is update cadence: Calculator + at every 4 days against Calculator & AI Math Solver's every 5 weeks. Calculator + also leads on ratings volume (10K vs 53). Calculator & AI Math Solver's advantage is rating (4.8 vs 4.6) and device support (4 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Calculator & AI Math Solver sells 6 in-app purchases, starting at $4.89 per 7 days. Whichever you choose, the download price is not the number that matters.

Calculator & AI Math Solver holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 53, so its average is the more settled of the two. Written reviews complicate that: 85% of Calculator +'s written reviews are positive against 83% of Calculator & AI Math Solver's, so the app with the better star average is not the one people write more warmly about.

Calculator + ships an update every 4 days, Calculator & AI Math Solver every 5 weeks. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
