# Calculator + vs Construction Calculator

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Construction Calculator sells 8 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Calculator + against 4.7 for Construction Calculator. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 625, so its average is the more settled of the two.
