# Calculator Plus #1 vs Calculator+

The clearest difference is rating: Calculator Plus #1 at 4.8 against Calculator+'s 4.0. Calculator Plus #1 also leads on ratings volume (5.1K vs 1) and update cadence (every 5 weeks vs every 5 months). Calculator+'s advantage is in-app purchases (none vs 7) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Calculator Plus #1 sells 7 in-app purchases, starting at $0.99 per month. Calculator+ asks for nothing beyond the download.

Calculator Plus #1 holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Calculator Plus #1 has 5.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of Calculator Plus #1'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 Plus #1 ships an update every 5 weeks, Calculator+ every 5 months. The most recent releases landed on October 18, 2026 and October 16, 2026 respectively.
