# Basic Calculator vs Calculator+

The clearest difference is rating: Basic Calculator at 4.8 against Calculator+'s 4.0. Basic Calculator also leads on ratings volume (3.2K vs 1) and update cadence (every 2 months vs every 5 months). Calculator+'s advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

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

Basic Calculator holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Basic Calculator has 3.2K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 74% of Basic Calculator's written reviews are positive against 100% of Calculator+'s, so the app with the better star average is not the one people write more warmly about.

Basic Calculator ships an update every 2 months, Calculator+ every 5 months. The most recent releases landed on September 23, 2026 and August 11, 2026 respectively.
