Verdict
The clearest difference is review sentiment: Teo English at 100% against Introvert's 48%. Teo English also leads on rating (5.0 vs 4.7). Introvert's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (906 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Introvert sells 10 in-app purchases, starting at $6.99 per month and Teo English sells 4 in-app purchases, starting at $17.99 per month. Whichever you choose, the download price is not the number that matters.
Teo English holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Introvert has 906 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 48% of Introvert's written reviews are positive against 100% of Teo English's.
Introvert ships an update every 11 days, Teo English fortnightly. The most recent releases landed on November 11, 2026 and November 10, 2026 respectively.
