# Conversion Calculator Plus vs Unit Converter and Conversion

The clearest difference is update cadence: Conversion Calculator Plus at every 6 days against Unit Converter and Conversion's every 10 months. Conversion Calculator Plus also leads on ratings volume (15K vs 48) and rating (4.7 vs 4.5). Unit Converter and Conversion's advantage is review sentiment (82% vs 69%) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Conversion Calculator Plus sells 1 in-app purchase, starting at $9.99 per year and Unit Converter and Conversion sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Conversion Calculator Plus holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Conversion Calculator Plus has 15K ratings behind it against 48, so its average is the more settled of the two. Written reviews complicate that: 69% of Conversion Calculator Plus's written reviews are positive against 82% of Unit Converter and Conversion's, so the app with the better star average is not the one people write more warmly about.

Conversion Calculator Plus ships an update every 6 days, Unit Converter and Conversion every 10 months. The most recent releases landed on October 16, 2026 and October 11, 2026 respectively.
