# Calculator Smart vs Calculator ×

The clearest difference is review sentiment: Calculator × at 73% against Calculator Smart's 36%. Calculator Smart's advantage is rating (4.7 vs 4.5) and device support (6 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Calculator Smart sells 3 one-off in-app purchases and Calculator × sells 4 in-app purchases, starting at $4.99 per year. Whichever you choose, the download price is not the number that matters.

Calculator Smart holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 494 and 143 respectively. Written reviews complicate that: 36% of Calculator Smart's written reviews are positive against 73% of Calculator ×'s, so the app with the better star average is not the one people write more warmly about.

Calculator Smart ships an update every 4 months, Calculator × every 2 months. The most recent releases landed on September 12, 2026 and September 21, 2026 respectively.
