# CONVERT UNITS vs Unit Converter

The clearest difference is rating: CONVERT UNITS at 4.7 against Unit Converter's 4.3. CONVERT UNITS also leads on ratings volume (1.4K vs 3) and monetization model (ad-supported vs free with in-app purchases). Unit Converter's advantage is review sentiment (100% vs 76%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. CONVERT UNITS sells 2 in-app purchases, starting at $0.99 per month and Unit Converter sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

CONVERT UNITS holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: CONVERT UNITS has 1.4K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 76% of CONVERT UNITS's written reviews are positive against 100% of Unit Converter's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 9 days. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
