Hear exactly which sound gave you away.
Read a phrase out loud. HolosAccent scores it sound by sound, flags the phonemes that slipped, and turns the ones you keep missing into drills — while Murzik the cat grows up with every take.

The Practice screen walks you through the same four steps every time. A take lasts a few seconds; the whole loop is about two minutes.
Choose a CEFR band from A1 to C2 and a topic. Tap the speaker to hear the phrase from a native American or British voice — slower if you need the detail.
Tap the purple button, read the phrase out loud, tap again. No lesson to sit through, no setup.
A score out of 100, up to five stars, and every word that slipped — with the sound we expected next to the one we heard.
Sounds you keep missing rise to the top of the Sounds tab. Tap one to practise it in the very words where it failed.
Every take is compared with the phrase sound by sound. Here is how to read what comes back.
Every take earns at least one star. A phrase counts as passed once you score 80 or more on it.
Tap it to hear the right sound, or start a drill built from it. Mistakes that the reference voice makes too are not held against you.
Every take feeds a running tally per phoneme. Instead of a vague score, you get an ordered list of the sounds worth your next ten minutes, and a drill built from the words where each one failed.

CEFR bands, from A1 (short everyday phrases) to C2 (long, dense sentences). Pick one on the Practice screen and switch whenever you like — it only sets which phrases you get.
Every passed phrase, accurate take and finished daily challenge earns XP. XP raises your level, and your level grows Murzik — from a kitten to a veteran cat.
Score 80 or more on a phrase for the first time. The harder the band, the more it pays — a C2 phrase is worth three A1s.
A bonus for every accurate take, even on a phrase you have passed before. 90+ pays double.
Every day you complete the daily challenge counts towards your level too.
Nine stages, each with a new look, a new title and a card to share. Everyone starts as a kitten. What each stage looks like, you find out in the app.

?The ring on the Practice screen fills with every take. Close it to count the day.
Counts the days in a row you reached your goal. Missed one? A streak freeze can cover it.
Five new phrases picked for you each day. A take of 60 or more ticks a phrase off; finish all five for +10 XP.

Badges are earned by practice, not by opening the app: three days in a row, your first hundred phrases, getting θ and ð right in think and this. Each one has its own Murzik.

Hear the phrase in American or British English, slowed down when you need the detail.
Your average, how it moved over two weeks, and which sounds pulled it up or down — in one report.
Type in a sentence you actually need to say and score that instead.
Takes, stats and streaks live in your account, so a new phone picks up where you left off.
Lavender, lilac, plum, a violet night and cool mint and lagoon looks — pick yours in Settings.
Short, practical notes on the sounds that trip people up — TH, the schwa, L and R, word stress — and how to fix them.
We use your recordings for two things only: scoring your pronunciation and your own history, where you can play a take back next to the native audio. They are never used to train AI or for anything else. Scoring is done entirely by machine — no person listens, and only you can reach your takes. They are kept for as long as your account exists, or until you delete them.
Billing is handled by the App Store or Google Play, shown in your local currency before you confirm.
Yes. Your daily quota, your subscription and your history live on the account, which is why progress survives a reinstall. Sign in with Google or Apple — one tap, no password to remember.
Yes — for as long as your account exists, or until you delete them. We use them only to score your pronunciation and to keep your history, so you can replay a take next to the native audio — never to train AI, and nowhere else. Only you can reach them, through a link that expires in an hour, and no person ever listens. Settings → Clear my history deletes every recording at once; deleting the account removes everything.
Reference audio in American and British English, at a speed you choose. Scoring itself is accent-aware: it compares what you said to the phrase, sound by sound.
HolosAccent is not a classroom course and does not grade you — it works as an individual trainer, judging each take sound by sound. The model can mishear, but this is rare; reference errors are subtracted from your statistics.
No. A1–C2 is how hard the phrases are, and you pick it yourself. Your level (LV) is earned with XP from practice and decides which stage Murzik is at. A beginner can be level 20 after months of A1 practice.
Practice phrases come from public text corpora published under permissive open-source licenses; we filter, deduplicate and sort them into CEFR difficulty levels. Reference audio is synthesized on our own servers. Your recordings are never used to train anything.
In your App Store or Google Play subscription settings, any time. Access continues to the end of the period you already paid for — cancelling does not cut it short.
Yes. Delete the account from inside the app (Settings) or on the account deletion page: history, statistics and any saved recordings go with it.
No. XP only grows — a bad take never rolls you back. The one exception is Settings → Clear my history, which wipes the takes your XP is counted from.
