# Thea vs Lernix AI

The clearest difference is update cadence: Lernix AI at every 3 days against Thea's monthly. Thea's advantage is ratings volume (2.6K vs 6) and device support (4 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Thea sells 2 in-app purchases, starting at $12.00 per month and Lernix AI sells 4 in-app purchases, starting at $9.99 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 — 4.9 for Thea against 5.0 for Lernix AI. That said, the two scores are not equally well evidenced: Thea has 2.6K ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 93% of Thea's written reviews are positive against 100% of Lernix AI's.

Thea ships an update monthly, Lernix AI every 3 days. The most recent releases landed on November 4, 2026 and November 7, 2026 respectively.
