# Conversion Calculator Units vs Unit Convert

The clearest difference is ads: Unit Convert at none against Conversion Calculator Units's shown. Unit Convert also leads on monetization model (free vs free with in-app purchases) and review sentiment (100% vs 82%). Conversion Calculator Units's advantage is ratings volume (5K vs 13) and rating (4.7 vs 4.5). On price, update cadence, in-app purchases and device support there is nothing between them.

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

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 13, 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 Unit Convert's, so the app with the better star average is not the one people write more warmly about.

Conversion Calculator Units ships an update every 2 months, Unit Convert every 3 months. The most recent releases landed on October 13, 2026 and October 2, 2026 respectively.
