# Calculator vs Calculator ⁺⁻

The clearest difference is rating: Calculator ⁺⁻ at 4.7 against Calculator's 4.0. Calculator ⁺⁻ also leads on ratings volume (40 vs 4). Calculator's advantage is ads (none vs shown) and update cadence (every 3 months vs every 15 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Calculator ⁺⁻ holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Calculator ⁺⁻ has 40 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of Calculator's written reviews are positive against 50% 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 3 months, Calculator ⁺⁻ every 15 months. The most recent releases landed on September 25, 2026 and October 8, 2026 respectively.
