# CalcFast vs Calculator

The clearest difference is in-app purchases: CalcFast at none against Calculator's 1. CalcFast also leads on ads (none vs shown) and review sentiment (78% vs 69%). Calculator's advantage is rating (4.6 vs 4.2) and iOS requirement (15.0 vs 27.1). On price, ratings volume, update cadence and device support there is nothing between them.

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

Calculator holds the better App Store score, 4.6 against 4.2. Both are backed by a comparable volume of ratings — 21 and 17 respectively. Written reviews complicate that: 78% of CalcFast's written reviews are positive against 69% of Calculator's, so the app with the better star average is not the one people write more warmly about.

CalcFast ships an update every 2 months, Calculator monthly. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
