# Calculator 3D vs Calculator ⁺⁻

The clearest difference is rating: Calculator ⁺⁻ at 4.7 against Calculator 3D's 4.0. Calculator ⁺⁻ also leads on in-app purchases (none vs 1) and ratings volume (40 vs 4). Calculator 3D's advantage is update cadence (every 5 weeks vs every 15 months) and review sentiment (75% vs 50%). On price, ads and device support there is nothing between them.

Both are free to download. Calculator 3D sells 1 one-off in-app purchase. Calculator ⁺⁻ asks for nothing beyond the download.

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: 75% of Calculator 3D'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 3D ships an update every 5 weeks, Calculator ⁺⁻ every 15 months. The most recent releases landed on October 18, 2026 and October 8, 2026 respectively.
