# UDictionary Translator vs DeepL Translate

The clearest difference is ads: DeepL Translate at none against UDictionary Translator's shown. DeepL Translate also leads on rating (4.8 vs 4.6) and chart position (#65 vs unranked). UDictionary Translator's advantage is iOS requirement (11.0 vs 17.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. UDictionary Translator sells 9 in-app purchases, starting at $2.49 per 7 days and DeepL Translate sells 8 in-app purchases, starting at $10.49 per month. Whichever you choose, the download price is not the number that matters.

DeepL Translate holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 9.3K and 13K respectively. Written reviews complicate that: 59% of UDictionary Translator's written reviews are positive against 53% of DeepL Translate's, so the app with the better star average is not the one people write more warmly about.

UDictionary Translator ships an update fortnightly, DeepL Translate weekly. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
