# Basic Calculator vs Calculator HD++

The clearest difference is in-app purchases: Calculator HD++ at none against Basic Calculator's 1. Calculator HD++ also leads on update cadence (monthly vs every 2 months) and iOS requirement (10.0 vs 15.0). Basic Calculator's advantage is rating (4.8 vs 4.4) and ratings volume (3.2K vs 277). On price, review sentiment, ads and device support there is nothing between them.

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

Basic Calculator holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Basic Calculator has 3.2K ratings behind it against 277, so its average is the more settled of the two. Written reviews complicate that: 76% of Basic Calculator's written reviews are positive against 82% of Calculator HD++'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 HD++ monthly. The most recent releases landed on October 18, 2026 and October 17, 2026 respectively.
