The call

Language Reactor and Sophia both sit at 4.5 stars, but that hides the real split: 82% of Language Reactor's written reviews are positive against 70% of Sophia's. Language Reactor also leads on ratings volume (832 vs 154). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Language Reactor sells 8 in-app purchases, starting at $2.99 per 7 days and Sophia sells 13 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Sophia holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Language Reactor has 832 ratings behind it against 154, so its average is the more settled of the two. Written reviews complicate that: 82% of Language Reactor's written reviews are positive against 70% of Sophia's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Language Reactor ships an update every 8 days, Sophia every 6 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
