# Calculator+ Photo Math Solver vs Calculator

Calculator also leads on rating (4.5 vs 4.1) and iOS requirement (13.0 vs 16.0). Calculator+ Photo Math Solver's advantage is review sentiment (75% vs 45%) and update cadence (weekly vs every 3 weeks).

Both are free to download. Calculator+ Photo Math Solver sells 3 in-app purchases, starting at $4.99 per 7 days and Calculator sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Calculator holds the better App Store score, 4.5 against 4.1. Both are backed by a comparable volume of ratings — 21 and 8 respectively. Written reviews complicate that: 75% of Calculator+ Photo Math Solver's written reviews are positive against 45% of Calculator's, so the app with the better star average is not the one people write more warmly about.
