# Conversion Calculator Units vs Ultimate Convertor

The clearest difference is in-app purchases: Ultimate Convertor at none against Conversion Calculator Units's 1. Ultimate Convertor also leads on ads (none vs shown) and review sentiment (100% vs 82%). Conversion Calculator Units's advantage is ratings volume (5K vs 2) and rating (4.7 vs 4.5). On price and device support there is nothing between them.

Both are free to download. Conversion Calculator Units sells 1 one-off in-app purchase. Ultimate Convertor asks for nothing beyond the download.

Conversion Calculator Units holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Conversion Calculator Units has 5K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of Conversion Calculator Units's written reviews are positive against 100% of Ultimate Convertor's, so the app with the better star average is not the one people write more warmly about.
