About this app
Speak English more clearly — and know where to focus next. Lingo listens to the sound of your voice, compares it with a reference, and shows a per-word clarity heatmap. Try the phrase again, hear your attempt beside the reference voice, and build a practice plan around the sounds that need attention. Scoring runs on your iPhone: no account, no voice upload, and no connection required. TUNED TO YOUR FIRST LANGUAGE Choose your first language and Lingo prioritizes English sounds that often need extra practice for speakers of that language. Ten language tracks cover Spanish, Mandarin, Hindi, Arabic, Portuguese, Korean, Japanese, Vietnamese, French, and Russian. The goal is clearer speech, never erasing who you are. PRACTICE THAT HAS A PURPOSE • 45 English sounds with focused guidance • 207 minimal-pair exercises such as ship and sheep • 34 rhythm, stress, linking, reduction, and intonation drills • 35 daily, academic, interview, business, and IELTS-style speaking scenarios • A spoken placement that seeds your first practice plan • Spaced repetition that brings sounds back when they are due • Respectful local reminders at the time you choose PRIVATE BY DESIGN Your recording is analyzed in memory for scoring and discarded. Lingo has no account, advertising, analytics SDK, or voice upload. If on-device speech recognition is unavailable for a device or locale, Lingo says so and keeps the acoustic score local instead of using a server. FREE, THEN CAPABILITY-GATED Free includes the spoken placement, eight practice reps each day, three starter sounds, and one minimal-pair contrast. Pro unlocks unlimited reps, every sound and exercise, all first-language tracks, scenarios, prosody drills, and progress analytics. Monthly and Yearly are auto-renewing subscriptions and Lifetime is a one-time purchase. An introductory free trial is not offered in every region: where the App Store offers one for your region and Apple Account, Lingo shows its exact length beside the purchase button and the App Store shows it again before you confirm. Exact localized prices are always shown by the App Store before purchase; if StoreKit cannot load them, Lingo shows a retry state and disables purchase instead of inventing a price. Subscriptions renew unless canceled at least 24 hours before the current period ends. Manage or cancel in App Store account settings.

Latest release
What’s New
Honest pricing, everywhere. The paywall now reads its free-trial offer from the App Store for your own region instead of assuming one, so Lingo mentions a trial only where Apple will actually give you one, and states the exact length Apple will honour. The trial-ending reminder is now scheduled only when a trial really started, and a purchase that needs a Family Organizer's approval says so on screen instead of leaving it silent.

Ratings growth
Baseline captured. Growth appears after the crawler observes a changed rating count.
Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
