# Kalculator vs Calculator Smart

The clearest difference is rating: Calculator Smart at 4.7 against Kalculator's 4.2. Calculator Smart also leads on ratings volume (498 vs 19). Kalculator's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Kalculator sells 7 one-off in-app purchases and Calculator Smart sells 3 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 4.2. That said, the two scores are not equally well evidenced: Calculator Smart has 498 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 38% of Kalculator's written reviews are positive against 36% of Calculator Smart's, so the app with the better star average is not the one people write more warmly about.

Kalculator ships an update every 6 weeks, Calculator Smart every 4 months. The most recent releases landed on November 1, 2026 and October 23, 2026 respectively.
