# Basic Calculator vs Calculator 4.0

On the App Store both sit at effectively the same score — 4.8 for Basic Calculator against 4.8 for Calculator 4.0. That said, the two scores are not equally well evidenced: Basic Calculator has 3.2K ratings behind it against 53, so its average is the more settled of the two.
