# Calculator # vs Haseba Calculator

The clearest difference is ads: Haseba Calculator at none against Calculator #'s shown. Haseba Calculator also leads on review sentiment (78% vs 60%). Calculator #'s advantage is ratings volume (36K vs 3.8K) and iOS requirement (12.1 vs 17.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Calculator # sells 6 in-app purchases, starting at $1.49 per month and Haseba Calculator sells 7 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
