# Unit Converter HD. vs Unit Converter

The clearest difference is review sentiment: Unit Converter HD. at 94% against Unit Converter's 0%. Unit Converter HD. also leads on ratings volume (645 vs 2). Unit Converter's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Unit Converter HD. sells 1 one-off in-app purchase and Unit Converter sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Unit Converter holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Unit Converter HD. has 645 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 94% of Unit Converter HD.'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.
