Thai has five tones, its own alphabet, and very little in common with English. There is no shortcut around that: the language opens up word by word. Obby Thai gives you those words — 6,161 of them, from your first สวัสดี to advanced fluency, every one spoken aloud in native-quality audio. LEARNING ON AUTOPILOT Press one button and study. Launch Learning builds every session for you — no setup, no decisions. It introduces a few new words at the right moment, quizzes what you just met, and brings words back with smart spaced repetition (FSRS) exactly when you are about to forget them. Words that keep slipping away are detected and given gentler questions until they stick, and once your review queue is empty, refresher sessions keep your strongest vocabulary alive. Everyone starts at A1; the pace adapts to how you actually perform. QUIZ-FIRST, ALWAYS You learn by answering, not by scrolling through lessons: • Multiple choice in both directions — Thai → English and back • Listening quizzes: hear the word, pick the meaning • Matching pairs for fast recall • Thai alphabet drills: all 44 consonants with their class, every vowel — the foundation for reading and for the tone rules • Tap the speaker on any word to hear it again, as often as you like Prefer control? Configure quiz builds your own session: length, topics, CEFR level, direction, timer. And Review words replays only your mistakes — never padding, never filler. WATCH YOURSELF LEVEL UP A knowledge bar on the home screen tracks every word you truly know, your CEFR level from A1 to C2, and a title that evolves as your vocabulary grows. Streaks, word goals and 71 achievements mark the road — including one for meeting all 6,161 words. WHAT'S INSIDE • 6,161 Thai words and phrases across 24 real-life topics: food, travel, work, health, feelings, numbers and more • Native-quality audio for every single word — nothing left silent • Full CEFR range A1 to C2: this is not a phrasebook • Romanized pronunciation guide: show it, tap to reveal, or switch it off as your reading improves • Learn Thai FROM English, French, Russian, Spanish, German or Italian THE STORY Obby is built by one person. I moved to Thailand, needed to actually learn the language — not greetings, the real vocabulary — and couldn't find an app that took an adult learner from beginner to advanced without accounts, ads and subscriptions in the way. So I built it myself, end to end. The little mascot is named after Obby, a real Thai teacher whose classes inspired this app. A share of every sale supports her. HONEST AND YOURS • Free to try — one single purchase unlocks all 6,161 Thai words, forever: no subscription, no ads • No account, no sign-up: open the app and start • Works 100% offline — every word and every audio clip ships inside the app • Zero data collected. The privacy policy is one page • Your progress stays on your device and is restored by your phone's own backup One real word at a time, spoken properly, until it sticks — from A1 to C2.
