# Basic Calculator vs Calculator Tax+

The clearest difference is ads: Calculator Tax+ at none against Basic Calculator's shown. Calculator Tax+ also leads on review sentiment (92% vs 76%) and iOS requirement (7.1 vs 15.0). Basic Calculator's advantage is ratings volume (3.3K vs 13) and update cadence (every 2 months vs every 6 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Basic Calculator sells 1 one-off in-app purchase and Calculator Tax+ 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 — 4.8 for Basic Calculator against 4.8 for Calculator Tax+. That said, the two scores are not equally well evidenced: Basic Calculator has 3.3K ratings behind it against 13, so its average is the more settled of the two.
