# Calculator Mini vs Calculator ⁺⁻

The clearest difference is review sentiment: Calculator Mini at 100% against Calculator ⁺⁻'s 50%. Calculator Mini also leads on iOS requirement (11.0 vs 15.0). Calculator ⁺⁻'s advantage is rating (4.7 vs 2.5) and update cadence (every 15 months vs every 51 months). On price, ads, in-app purchases and monetization model 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 2.5. That said, the two scores are not equally well evidenced: Calculator ⁺⁻ has 42 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Calculator Mini'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 Mini ships an update every 51 months, Calculator ⁺⁻ every 15 months. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
