# Language Reactor vs Sophia

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.

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.

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.
