# 爱主题 vs Calculator Pro

爱主题 and Calculator Pro both sit at 4.9 stars, but that hides the real split: 100% of Calculator Pro's written reviews are positive against 50% of 爱主题's. Calculator Pro also leads on ratings volume (92 vs 19). 爱主题's advantage is update cadence (every 2 weeks vs every 2 months). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. 爱主题 sells 10 in-app purchases, starting at $0.99 per month and Calculator Pro sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

爱主题 holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 19 and 92 respectively. Written reviews complicate that: 50% of 爱主题's written reviews are positive against 100% of Calculator Pro's, so the app with the better star average is not the one people write more warmly about.

爱主题 ships an update every 2 weeks, Calculator Pro every 2 months. Both last shipped on October 24, 2026.
