# Currency vs Unit Converter

The clearest difference is review sentiment: Currency at 80% against Unit Converter's 57%. Currency also leads on rating (4.8 vs 4.6) and chart position (#79 vs unranked). Unit Converter's advantage is update cadence (weekly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Currency sells 3 in-app purchases, starting at $19.99 per year and Unit Converter sells 12 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.

Currency holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Currency has 78K ratings behind it against 14K, so its average is the more settled of the two. Written reviews point the same way: 80% of Currency's written reviews are positive against 57% of Unit Converter's.

Currency ships an update monthly, Unit Converter weekly. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
