# Convert vs Unit Converter and Conversion

The clearest difference is rating: Convert at 4.7 against Unit Converter and Conversion's 4.4. Convert also leads on update cadence (every 3 months vs every 9 months) and iOS requirement (12.0 vs 15.0). Unit Converter and Conversion's advantage is review sentiment (82% vs 70%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Convert sells 2 in-app purchases, starting at $0.99 per 6 months and Unit Converter and Conversion sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Convert holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 126 and 49 respectively. Written reviews complicate that: 70% of Convert'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.

Convert ships an update every 3 months, Unit Converter and Conversion every 9 months. Both last shipped on November 6, 2026.
