# Calculator₊ vs Calculator·

The clearest difference is ratings volume: Calculator₊ at 1.7M against Calculator·'s 34K. Calculator₊ also leads on update cadence (every 3 weeks vs every 3 months) and chart position (#102 vs unranked). Calculator·'s advantage is review sentiment (84% vs 63%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Calculator₊ sells 12 in-app purchases, starting at $0.99 per month and Calculator· sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Calculator· holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Calculator₊ has 1.7M ratings behind it against 34K, so its average is the more settled of the two. Written reviews point the same way: 63% of Calculator₊'s written reviews are positive against 84% of Calculator·'s.

Calculator₊ ships an update every 3 weeks, Calculator· every 3 months. Both last shipped on October 25, 2026.
