# Unit Converter ++ vs UC

The clearest difference is rating: UC at 3.0 against Unit Converter ++'s 1.6. UC also leads on ads (none vs shown) and update cadence (every 2 months vs every 9 months). Unit Converter ++'s advantage is review sentiment (20% vs 0%) and ratings volume (10 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

UC holds the better App Store score, 3.0 against 1.6. That said, the two scores are not equally well evidenced: Unit Converter ++ has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of Unit Converter ++'s written reviews are positive against 0% of UC's, so the app with the better star average is not the one people write more warmly about.

Unit Converter ++ ships an update every 9 months, UC every 2 months. The most recent releases landed on October 9, 2026 and October 17, 2026 respectively.
