About this app

Chinese pronunciation is not “hard.” It’s precise — and most language apps train it wrong.

TonePerfect is an AI-powered Mandarin speaking coach. You talk. The AI listens, scores every syllable, and tells you exactly what went wrong — the initial, the final, the tone, or the transition between them. No vague “try again.” No gamified noise. Real feedback on real speech.

▶ WHAT’S INSIDE

• AI Voice Call — have a real Mandarin conversation with an AI tutor. Pick a topic, speak naturally, and get a full post-call review with every mistake, every tone slip, and what to practice next. This is the closest thing to a private native tutor that fits in your pocket.

• Instant Pronunciation Analysis — record a syllable, word, or full sentence and get objective 0–100% scoring on tone accuracy AND pronunciation accuracy, with a syllable-by-syllable breakdown.

• Tone & Tone-Pair Mastery — Mandarin lives in the transitions. Dedicated drills for every tone pair (1-2, 2-3, 3-4, neutral combinations…), not just isolated tones.

• Targeted Initial & Final Correction — the AI isolates whether your b/p, zh/ch/sh, or -ang/-eng/-ong was off, and drills that specific sound until it clicks.

• Arcade Mode — Falling Tones, Tone Sprint, Tone Twins, Tone Rush, Tone Drill. Fast, competitive games that train your ear and mouth at the same time.

• Adaptive Placement Test — a quick assessment picks your real starting level so you don’t waste time on what you already know.

• Daily Sessions & Missions — short, focused daily routines with streaks, energy, and weekly goals. Duolingo rhythm, actual pronunciation content.

• Smart Spaced Repetition — the app learns your weak syllables, tones, and tone pairs, and forces you to face them until they’re solid.

• Interactive Pinyin Chart — every valid Mandarin syllable, tappable, in one screen. Drill any cell on demand.

• HSK 1–6 Content Packs — vocabulary and sentences aligned with the HSK levels you actually need.

• Native Reference Audio — compare your recording to a native speaker, A/B style.

• Progress You Can Measure — a full stats screen with tone accuracy over time, initial/final mastery, sentence-level trends, and leaderboard.

▶ WHO THIS APP IS FOR

• Learners stuck at “people understand me, but I sound wrong.”
• HSK 1 – HSK 6 students prepping for listening and speaking.
• Self-study learners who want an honest AI coach, not more flashcards.
• Heritage speakers polishing their accent.
• Anyone who’s ever been told “your tones are off” and given up guessing why.

▶ WHAT THIS APP IS NOT

❌ Not a vocabulary flashcard app.
❌ Not a grammar course.
❌ Not a toy.

TonePerfect is a dedicated speaking tool. You practice out loud. The AI tells you the truth.

▶ WHY IT WORKS

Most apps grade you on whether a pattern-matcher recognized your word. TonePerfect evaluates three independent channels on every syllable:

1. Initial (b, p, m, zh, ch, sh, r, j, q, x…)
2. Final (-an, -en, -ang, -eng, -ong, -ian, -üe…)
3. Tone (1st, 2nd, 3rd, 4th, neutral) — and the tone PAIR, because real Mandarin is transitions.

You see exactly where the error is. You fix that specific layer. You move on.

▶ BUILT FOR DAILY USE

• Streaks, energy, daily missions, and achievements keep you coming back.
• Short sessions (5/10/15 min goals) — pick your pace in onboarding, change it anytime.
• Smart reminders. No spam.
• Works offline for most drills, online for AI chat and advanced analysis.
• Sign in with Apple or Google, sync across devices.

▶ PREMIUM

TonePerfect.app Premium unlocks the AI Voice Call, unlimited daily sessions, the full HSK library, advanced stats, and all arcade modes. Free tier lets you try every core feature before you upgrade.

Ratings and reviews

despite learning Mandarin for two years I still have some pronunciation issues, minor but problematic. This app can hear what you are getting wrong and tell you how to fix it. Is it the initial. the final, the tone, clarity of the sounds. This really allows you to practice what issue you might have. Be it saying the syllables in isolation or in sentences. Very helpful!

very simular to Duolingo just less features and more accent on pronunciation. Also, there are mistakes with some words and readings. Very annoying the recording button, 60% of the time it is not recording the voice while holding or end the recording earlier or something else.. 🙄 71.53$ per year is way too much for this quality to be honest. UPD. looks like the recording buttom was fixed 😀

Excellent application with a great design and a very clear UI. It helps a lot with mastering Chinese tones. It’s still a bit rough at the moment, but hopefully all the small issues will be resolved in future versions.
