# Calculator+= vs Calculator

The clearest difference is rating: Calculator at 4.3 against Calculator+='s 3.6. Calculator+='s advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, ratings volume and device support there is nothing between them.

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

Calculator holds the better App Store score, 4.3 against 3.6. Both are backed by a comparable volume of ratings — 7 and 20 respectively. Written reviews complicate that: 50% of Calculator+='s written reviews are positive against 33% 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 5 weeks, Calculator every 3 months. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
