# Calculator vs Smart

The clearest difference is rating: Smart at 3.0 against Calculator's 1.8. Smart also leads on update cadence (every 5 weeks vs every 15 months). Calculator's advantage is review sentiment (20% vs 0%) and ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Smart holds the better App Store score, 3.0 against 1.8. That said, the two scores are not equally well evidenced: Calculator has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of Calculator's written reviews are positive against 0% of Smart's, so the app with the better star average is not the one people write more warmly about.

Calculator ships an update every 15 months, Smart every 5 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
