# Calculator ⁺⁻ vs Multi

The clearest difference is rating: Calculator ⁺⁻ at 4.7 against Multi's 4.1. Multi's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 15 months). On price, ratings volume, in-app purchases and device support 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 4.1. Both are backed by a comparable volume of ratings — 40 and 14 respectively. Written reviews complicate that: 50% of Calculator ⁺⁻'s written reviews are positive against 75% of Multi's, so the app with the better star average is not the one people write more warmly about.

Calculator ⁺⁻ ships an update every 15 months, Multi every 3 weeks. The most recent releases landed on October 8, 2026 and October 9, 2026 respectively.
