# 翻訳アプリはWeblio英語翻訳 vs UDictionary Translator

The clearest difference is rating: UDictionary Translator at 4.6 against 翻訳アプリはWeblio英語翻訳's 3.8. UDictionary Translator also leads on ratings volume (9.3K vs 5) and update cadence (fortnightly vs every 2 months). 翻訳アプリはWeblio英語翻訳's advantage is review sentiment (75% vs 59%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 翻訳アプリはWeblio英語翻訳 sells 1 in-app purchase, starting at $3.49 per month and UDictionary Translator sells 9 in-app purchases, starting at $2.49 per 7 days. Whichever you choose, the download price is not the number that matters.

UDictionary Translator holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: UDictionary Translator has 9.3K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 75% of 翻訳アプリはWeblio英語翻訳's written reviews are positive against 59% of UDictionary Translator's, so the app with the better star average is not the one people write more warmly about.

翻訳アプリはWeblio英語翻訳 ships an update every 2 months, UDictionary Translator fortnightly. Both last shipped on September 25, 2026.
