# Calculator· vs Calculator 4.0

The clearest difference is ratings volume: Calculator· at 34K against Calculator 4.0's 53. Calculator 4.0's advantage is update cadence (fortnightly vs every 3 months) and iOS requirement (12.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Calculator· sells 3 in-app purchases, starting at $0.99 per month and Calculator 4.0 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Calculator· against 4.8 for Calculator 4.0. That said, the two scores are not equally well evidenced: Calculator· has 34K ratings behind it against 53, so its average is the more settled of the two.

Calculator· ships an update every 3 months, Calculator 4.0 fortnightly. The most recent releases landed on September 27, 2026 and September 10, 2026 respectively.
