# Unit Converter and Conversion vs Unit Converter

The clearest difference is update cadence: Unit Converter at every 9 days against Unit Converter and Conversion's every 10 months. Unit Converter also leads on review sentiment (100% vs 82%). Unit Converter and Conversion's advantage is ratings volume (48 vs 3) and rating (4.5 vs 4.3). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Unit Converter and Conversion holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Unit Converter and Conversion has 48 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 82% of Unit Converter and Conversion's written reviews are positive against 100% of Unit Converter's, so the app with the better star average is not the one people write more warmly about.

Unit Converter and Conversion ships an update every 10 months, Unit Converter every 9 days. The most recent releases landed on September 22, 2026 and September 10, 2026 respectively.
