About

School taught you standard English. FluentIn teaches you how people on that street — and in that industry — actually talk. You already know the words. What you miss is the local version: "on line" instead of "in line", "deadass" instead of "seriously", "let me get a regular coffee" instead of a full sentence with please. FluentIn drills exactly that gap. HOW IT WORKS • Read the situation in your language (English or 繁體中文). • Hold the button and say it the way a local would — or tap the blanked word and type it. • Get one of three verdicts: Local — that's how they say it. Close — meaning right, wording not local. Not it. • Local or Close reveals the card: the phrase, who says it, where it's safe, where to avoid it, where it came from — and, for many phrases, a real clip of someone saying it. • Not it? The answer stays hidden. Try again, ask a friend (share the question as a card — to a real friend or your AI assistant), or pass for now. FluentIn is not a question bank to race through: going to find the answer is what makes it stick. WHAT MAKES IT DIFFERENT • Every phrase carries a social card: age, community, register, the rooms where it lands and the rooms where it doesn't. • Real speakers, not voice actors: hear the phrase in the wild via YouTube. • A judge that knows the difference between "right meaning" and "right wording" — the feedback textbooks can't give. • Five hint levels, from one blanked key word to nothing at all. Complete a pack at a harder level and its badge upgrades: green, bronze, silver, gold, dark. PACKS • Fluent in New York — bodega, stoop, yerrr, the train, OD, brick, on line… • Fluent in Silicon Valley — LGTM, ship it, on call, runway, TC… • Fluent in Wall Street — priced in, bips, comp day, the staffer… • Fluent in Coffee Shops — order like a regular (unaffiliated with any chain). • Fluent in Tainan and Fluent in Shanghai — the local Mandarin: 牛肉湯、府城、阿拉、拎得清… (answers in Mandarin). More cities and industries are on the way. For intermediate and advanced learners: people moving to a city, joining a new workplace, or tired of missing the joke. Speech recognition runs on your device via Apple's speech framework. Optional: add your own Gemini API key in Settings and an AI judge explains the grey-zone answers. No account. No FluentIn servers. Nothing sold.

Verdict

The call

The clearest difference is in-app purchases: Number Master at none against FluentIn's 7. Number Master also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). FluentIn's advantage is ads (none vs shown) and update cadence (daily vs every 5 days). On price there is nothing between them.
