Verdict

The call

The clearest difference is ads: Unit Convert at none against Unit Converter's shown. Unit Convert also leads on monetization model (free vs free with in-app purchases) and review sentiment (100% vs 88%). Unit Converter's advantage is update cadence (weekly vs every 3 months) and ratings volume (1.5K vs 13). On price and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Unit Converter sells 3 in-app purchases, starting at $2.99 per month and Unit Convert sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Unit Converter holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Unit Converter has 1.5K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 88% of Unit Converter'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.

UpkeepUpdate frequency

Unit Converter ships an update weekly, Unit Convert every 3 months. The most recent releases landed on October 16, 2026 and October 2, 2026 respectively.
