# Khmer Calendar vs Calculator Smart

The clearest difference is price: Calculator Smart at Free against Khmer Calendar's $2.99. Calculator Smart also leads on rating (4.7 vs 4.5) and ratings volume (498 vs 93). Khmer Calendar's advantage is review sentiment (75% vs 36%) and in-app purchases (none vs 3). On update cadence and iOS requirement there is nothing between them.

Calculator Smart is free to download; Khmer Calendar costs $2.99 up front. Calculator Smart sells 3 one-off in-app purchases. Khmer Calendar asks for nothing beyond the download.

Calculator Smart holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Calculator Smart has 498 ratings behind it against 93, so its average is the more settled of the two. Written reviews complicate that: 75% of Khmer Calendar'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.

Khmer Calendar ships an update every 3 months, Calculator Smart every 4 months. Both last shipped on October 23, 2026.
