# All Unit Conversion vs Unit Converter

The clearest difference is review sentiment: All Unit Conversion at 50% against Unit Converter's 0%. All Unit Conversion also leads on in-app purchases (none vs 1) and ratings volume (17 vs 2). Unit Converter's advantage is rating (5.0 vs 4.6) and device support (3 vs 1). On price, ads and monetization model there is nothing between them.

Both are free to download. Unit Converter sells 1 one-off in-app purchase. All Unit Conversion asks for nothing beyond the download.

Unit Converter holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: All Unit Conversion has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of All Unit Conversion's written reviews are positive against 0% of Unit Converter's, so the app with the better star average is not the one people write more warmly about.
