# Language Reactor vs Sophia

The clearest difference is update cadence: Sophia at weekly against Language Reactor's every 3 weeks. Language Reactor's advantage is ratings volume (3.9K vs 174) and iOS requirement (13.0 vs 18.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Language Reactor sells 9 in-app purchases, starting at $3.49 per month and Sophia sells 10 in-app purchases, starting at $5.99 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 — 4.8 for Language Reactor against 4.7 for Sophia. That said, the two scores are not equally well evidenced: Language Reactor has 3.9K ratings behind it against 174, so its average is the more settled of the two. Written reviews are what separate them: 66% of Language Reactor's written reviews are positive against 70% of Sophia's.

Language Reactor ships an update every 3 weeks, Sophia weekly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
