# Calculator Smart vs Calculator Express with Notes

The clearest difference is review sentiment: Calculator Express with Notes at 69% against Calculator Smart's 36%. Calculator Express with Notes also leads on update cadence (monthly vs every 4 months). Calculator Smart's advantage is rating (4.7 vs 4.4) and ratings volume (494 vs 43). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calculator Smart sells 3 one-off in-app purchases and Calculator Express with Notes sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Calculator Smart holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Calculator Smart has 494 ratings behind it against 43, so its average is the more settled of the two. Written reviews complicate that: 36% of Calculator Smart's written reviews are positive against 69% of Calculator Express with Notes'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 Express with Notes monthly. The most recent releases landed on October 11, 2026 and October 7, 2026 respectively.
