# Calculator₊ vs Calculator

The clearest difference is in-app purchases: Calculator at none against Calculator₊'s 13. Calculator also leads on review sentiment (80% vs 63%). Calculator₊'s advantage is update cadence (every 3 weeks vs every 13 months) and ratings volume (1.7M vs 916). On price, rating, ads and iOS requirement there is nothing between them.

Both are free to download. Calculator₊ sells 12 in-app purchases, starting at $0.99 per month. Calculator asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Calculator₊ against 4.7 for Calculator. That said, the two scores are not equally well evidenced: Calculator₊ has 1.7M ratings behind it against 916, so its average is the more settled of the two. Written reviews are what separate them: 63% of Calculator₊'s written reviews are positive against 80% of Calculator's.

Calculator₊ ships an update every 3 weeks, Calculator every 13 months. The most recent releases landed on October 28, 2026 and October 23, 2026 respectively.
