# ChatterBaby vs Baby Translator

The clearest difference is rating: Baby Translator at 4.8 against ChatterBaby's 3.9. Baby Translator also leads on update cadence (fortnightly vs every 9 months). ChatterBaby's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Baby Translator sells 3 in-app purchases, starting at $6.99 per month. ChatterBaby asks for nothing beyond the download.

Baby Translator holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: ChatterBaby has 1.4K ratings behind it against 36, so its average is the more settled of the two. Written reviews complicate that: 41% of ChatterBaby's written reviews are positive against 13% of Baby Translator's, so the app with the better star average is not the one people write more warmly about.

ChatterBaby ships an update every 9 months, Baby Translator fortnightly. The most recent releases landed on November 11, 2026 and November 4, 2026 respectively.
