Designed to speak a language, not just study it! Most language apps focus on exercises, grammar rules, and tapping answers. Teacher AI is different. It was designed together with some of the world’s best language learners and creators to solve the hardest part of language learning: Speaking confidently in real conversations! Built with top language creators & polyglots Teacher AI isn’t a generic language app. It’s shaped by people who have: - Learned dozens of languages to fluency - Built large audiences teaching languages online - Spoken their target languages in the real world The idea: Fluency comes from activating words by speaking, not from doing more exercises. Speaking-first, not exercise-first With Teacher AI: - You don’t just recognize words --> you use them - You don’t fill in blanks --> you talk - You don’t wait until you’re “ready” --> you start speaking now Every session is designed to turn passive knowledge into active language skills through speaking. Natural conversations that actually feel real Teacher AI’s AI tutors are built for natural, flowing conversations. - Speak freely, not in scripted drills - Respond naturally, like in real life - Practice at your own pace, without pressure Many learners say conversations in Teacher AI feel more natural than in any other language app. And because it’s stress-free, you speak more. Which is what actually builds fluency. Activate words, track real progress Teacher AI tracks what truly matters for speaking: - Words you’ve actively spoken - Daily and weekly speaking progress - Streaks that reinforce real habits - You can literally see your fluency grow as your activated word count increases. Build a daily speaking habit Consistency beats motivation. Teacher AI helps you: - Speak a little every day - Build confidence gradually - Turn speaking into a natural habit Many learners join the Speak Every Day Challenge to stay accountable and motivated. Practice speaking multiple languages Practice real conversations in languages like: - Spanish, French, German, Italian, Portuguese, English, Chinese, Japanese, Korean, Indonesian, Dutch and 20 more languages.

Verdict

The call

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.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Fluyo ships an update every 2 weeks, Teacher AI fortnightly. The most recent releases landed on September 14, 2026 and September 22, 2026 respectively.
