HeyFluent uses the techniques that actually work: frequency-first spaced-repetition drills, reading and listening you can follow, and real speaking practice. It gets you fluent in the least time possible. Most apps drill you on words you'll never use and reward tapping over recall; HeyFluent starts with the words that come up most, so you understand the world around you sooner.
Most apps teach you to tap the right answer. HeyFluent builds real recall, comprehension and speech, starting with the words that come up most, so you get fluent faster.
Around a thousand words make up most of everyday speech. You learn those first, so you understand the world around you sooner.
Typing the answer from memory fixes a word far better than tapping it from a list. That is why you type, not tap.
Each word comes back right before you would forget it (the Leitner system), so nothing fades and nothing wastes your time.
A quick triage works out what you already know, so you never waste time on words you've got. You start exactly at your real edge and every session after that is aimed there.
You drill vocabulary in order of how often it is really used, with a Leitner system that shows each word right before you would forget it. Master the most frequent thousand and you understand most of everyday speech. This is the fastest route to real comprehension, not a random word list.
Full overviews of every tense, conjugation and rule, with example sentences. Drill a form, then tap straight through to exactly why it works. No more guessing why it was wrong.

| tú | comiste |
| él / ella | comió |
| nosotros | comimos |

Original stories graded to your level. Tap a word for an instant translation, save it with one press, and it drops into your spaced-review deck automatically. Reading quietly turns into vocabulary.
Marta abrió la puerta y, aunque hacía frío, sonrió al ver a su amiga.
Podcasts and clips at your level, with comprehension questions the AI writes and grades. Listening stops being passive and turns into measurable progress you can see.
Draft anything and get a clear, specific correction: what was wrong, why, and the natural way to say it. Not a red-pen score, an explanation you actually learn from.
Ayer comí en un restaurante muy buenos bueno.
Order a coffee, sort out a flat, handle an interview. An AI partner talks back turn by turn in your language, then reviews how you actually did. The safest way to fail until you no longer do.
Nothing you do is siloed. Words you master in drills raise the “% known” score on every story in the library, so you always know which text is at your level. Words you tap while reading become spaced-repetition cards, with the exact sentence you met them in. And when the AI catches a word you fumbled while speaking or writing, one tap drops it into your drill pool. Wherever you practise, HeyFluent knows where you actually are.
Set how many minutes you have each day, and HeyFluent builds the session for you: overdue flashcards first, then your single weakest grammar area, then a story or episode pitched at exactly your level, then a stretch of speaking or writing. Every item tells you why it's there.
It also measures your level from what you can actually do: the words you can produce, the grammar you've mastered, how the AI scores your speaking and writing, not hours logged. After your first week it fits your trajectory and shows the date you're on track to reach conversational (B1) and fluent (B2), and how moving your daily minutes changes that date. Because the level is measured rather than assumed, practice outside the app (living the language, a partner who speaks it) shows up in your trend and pulls the date closer.
Coming from Anki? You already believe in the two techniques that work: spaced repetition and typed active recall. HeyFluent runs on both — the same SM-2 scheduling underneath — but you never build a deck. Cards create themselves from the words you tap in real stories, each one carrying the sentence you found it in, and the mistakes the AI catches when you speak and write feed your drill pool. Anki only knows what you type into it. HeyFluent connects the whole loop.
Start with the words that matter, today. Every skill free, every week.
Add an accountability partner and they get a short email every week showing how your week went. You get a daily reminder yourself, and a nudge the moment your streak is at risk. Quietly falling off your goal gets a lot harder when someone else can see.
The same drills, reader and AI feedback across every language. Learn one or all three, with your progress saved separately for each.
Free is not a trial. Placement, unlimited drills, the reading library and the whole grammar reference are free forever, plus a weekly allowance of every AI skill, so you never stop speaking, writing and listening. Pro removes the caps.
You're the customer, not the product: no ads, no selling your data. The €12 pays for the AI feedback, which costs real money to run.
Free stays free for as long as you want, no time limit. €12 removes the weekly caps. Cancel anytime. If you downgrade, everything you have learned stays; you just go back to the weekly allowance.
Yes. Placement, unlimited frequency drills, the full reading library with tap-to-translate flashcards, and the whole grammar reference are free with no time limit. On top of that you get a weekly allowance of the AI skills — enough to speak, write and train your ear every single week without paying.
A2 is the second level of the European language scale (CEFR). At A2 you can handle everyday basics: shops, directions, routines, and simple conversations about familiar things. It is the point where the world around you starts to make sense.
No. You start free with no card, and your first week runs with full Pro access so you see everything at its best.
Yes, from settings. You keep the paid features until the end of the period you have paid for.
Real progress comes from producing the language: speaking and writing with feedback, as often as you can. That is exactly the part that runs on AI, and it has a real per-session compute cost, which is why the free plan meters it weekly. Paying to remove the caps is what keeps HeyFluent free of ads and free of selling your data.
It's an estimate, not a promise. HeyFluent measures your ability from what's actually in the app: the vocabulary you can produce, the grammar you've mastered, and how the AI scores your speaking and writing, then fits a trend across your recent days. The date shown is where that trend crosses conversational (B1) or fluent (B2). It needs about a week of practice before it appears, and it recalibrates as you go: it isn't fixed, and any practice you do outside the app naturally shows up in the trend.
It uses the same two techniques that make Anki work: spaced repetition (the same SM-2 scheduling) and typed active recall. The difference is that you never build or maintain a deck. Cards mint themselves from the words you tap while reading, each with the sentence you met it in, and the mistakes the AI catches in your speaking and writing feed your drill pool with one tap. Then everything connects: drill mastery updates the difficulty score on every story, so the system always knows, and shows you, where you really are.
Latin-American-norm Spanish, and standard German and French, focused on everyday usage.
I built HeyFluent for myself, to actually get fluent in Spanish. I use it every day. Every feature exists because I needed it to get through a real drill session or a real conversation, not because a growth team tested it on someone else.
