# UDictionary Translator vs AI Translator Ultimate

UDictionary Translator and AI Translator Ultimate both sit at 4.6 stars, but that hides the real split: 100% of AI Translator Ultimate's written reviews are positive against 59% of UDictionary Translator's. AI Translator Ultimate also leads on ads (none vs shown). UDictionary Translator's advantage is ratings volume (9.3K vs 40) and iOS requirement (11.0 vs 16.0). On price, rating, update cadence and in-app purchases 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 AI Translator Ultimate sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for UDictionary Translator against 4.7 for AI Translator Ultimate. That said, the two scores are not equally well evidenced: UDictionary Translator has 9.3K ratings behind it against 40, so its average is the more settled of the two. Written reviews are what separate them: 59% of UDictionary Translator's written reviews are positive against 100% of AI Translator Ultimate's.
