# Calculator vs Calculator Plus Pro

The clearest difference is rating: Calculator Plus Pro at 4.9 against Calculator's 3.0. Calculator's advantage is in-app purchases (none vs 1) and ratings volume (9.8K vs 33). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Calculator Plus Pro sells 1 one-off in-app purchase. Calculator asks for nothing beyond the download.

Calculator Plus Pro holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Calculator has 9.8K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 38% of Calculator's written reviews are positive against 36% of Calculator Plus Pro's, so the app with the better star average is not the one people write more warmly about.

Calculator ships an update every 4 months, Calculator Plus Pro every 7 months. Both last shipped on September 24, 2026.
