# Cook vs Conversion Calculator

The clearest difference is rating: Conversion Calculator at 4.8 against Cook's 4.3. Conversion Calculator also leads on ratings volume (165 vs 16) and review sentiment (100% vs 91%). Cook's advantage is update cadence (every 10 days vs every 5 weeks) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cook sells 1 one-off in-app purchase and Conversion Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Conversion Calculator holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Conversion Calculator has 165 ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 91% of Cook's written reviews are positive against 100% of Conversion Calculator's.

Cook ships an update every 10 days, Conversion Calculator every 5 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
