# Lingo Joy vs Synthi AI

The clearest difference is rating: Lingo Joy at 4.8 against Synthi AI's 4.0. Lingo Joy also leads on ads (none vs shown) and ratings volume (61 vs 2). Synthi AI's advantage is review sentiment (20% vs 0%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lingo Joy sells 15 in-app purchases, starting at $2.99 per month and Synthi AI sells 8 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Lingo Joy holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Lingo Joy has 61 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of Lingo Joy's written reviews are positive against 20% of Synthi AI's, so the app with the better star average is not the one people write more warmly about.

Lingo Joy ships an update every 5 days, Synthi AI every 9 days. Both last shipped on October 8, 2026.
