# Calculator + vs Calculator+

The clearest difference is rating: Calculator + at 4.6 against Calculator+'s 4.0. Calculator + also leads on update cadence (every 4 days vs every 5 months) and ratings volume (10K vs 1). Calculator+'s advantage is in-app purchases (none vs 12) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month. Calculator+ asks for nothing beyond the download.

Calculator + holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 85% of 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.

Calculator + ships an update every 4 days, Calculator+ every 5 months. The most recent releases landed on September 24, 2026 and August 11, 2026 respectively.
