# Calculator + vs Math Solver

The clearest difference is monetization model: Calculator + at free with in-app purchases against Math Solver's subscription. Calculator + also leads on update cadence (every 5 days vs monthly) and ratings volume (10K vs 29). Math Solver's advantage is review sentiment (96% vs 85%) and iOS requirement (13.0 vs 16.4). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Math Solver sells 1 in-app purchase, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Calculator + against 4.7 for Math Solver. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 29, so its average is the more settled of the two. Written reviews are what separate them: 85% of Calculator +'s written reviews are positive against 96% of Math Solver's.

Calculator + ships an update every 5 days, Math Solver monthly. The most recent releases landed on October 15, 2026 and October 7, 2026 respectively.
