# Fluyo vs Teacher AI

The clearest difference is monetization model: Fluyo at free with in-app purchases against Teacher AI's subscription. Fluyo also leads on iOS requirement (13.0 vs 16.4). Teacher AI's advantage is rating (4.3 vs 3.9). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. Fluyo sells 7 in-app purchases, starting at $9.99 per month and Teacher AI sells 9 in-app purchases, starting at $16.00 per month. Whichever you choose, the download price is not the number that matters.

Teacher AI holds the better App Store score, 4.3 against 3.9. Both are backed by a comparable volume of ratings — 448 and 262 respectively. Written reviews complicate that: 53% of Fluyo's written reviews are positive against 46% of Teacher AI's, so the app with the better star average is not the one people write more warmly about.

Fluyo ships an update every 2 weeks, Teacher AI fortnightly. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
