# Conversion Calculator Units vs Cook

The clearest difference is ads: Cook at none against Conversion Calculator Units's shown. Cook also leads on update cadence (every 10 days vs every 2 months) and review sentiment (91% vs 82%). Conversion Calculator Units's advantage is ratings volume (5K vs 13) and rating (4.7 vs 4.5). On price, in-app purchases, monetization model and device support there is nothing between them.

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

Conversion Calculator Units holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Conversion Calculator Units has 5K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 82% of Conversion Calculator Units's written reviews are positive against 91% of Cook's, so the app with the better star average is not the one people write more warmly about.

Conversion Calculator Units ships an update every 2 months, Cook every 10 days. The most recent releases landed on October 21, 2026 and October 1, 2026 respectively.
