Wat Kham
Read full descriptionHide full description
Learn Thai words you will actually use, and keep them. Wat Kham is a Thai vocabulary flashcard app built on spaced repetition. Each new word shows its meaning, script and pronunciation first. The app then quizzes you at the right moments, so the word moves into long-term memory. FSRS-6 scheduling decides when you see it again. START WITH THE ALPHABET AND YOUR FIRST 100 WORDS The free Thai Alphabet deck covers all 44 consonants with their class and sounds, plus vowels and tone marks. Core Thai 1–100 gives you the most useful everyday words in order, and Numbers covers prices, times and counting. A LIBRARY THAT GROWS WITH YOU Explore 91 vocabulary decks and 3,669 Thai-English cards: food, travel, transport, work, health, visas, conversation and grammar. A word that appears in several decks shares one review schedule, so you never study it twice. HEAR EVERY WORD Romanization with tone marks sits under the Thai script, and every answer is spoken aloud. Replay it whenever you like, with Normal or Slow pronunciation in Settings. Turn on listening mode to hear a word before you see it and recall its meaning by ear. STUDY IN EITHER DIRECTION Learn Thai from English, or practise English from Thai. Switch direction in Settings. SEE YOUR PROGRESS Choose how many new words to learn each day, keep a daily streak, and see on the dashboard which words are strong and which need practice. Search any word by Thai, English or sound, open its details, hear it and start studying. Reminders keep you on schedule, and one tap undoes a mistaken answer. A CARD THAT FEELS REAL Ivory paper cards, jade covers and gold temple ornament, with tactile flips and swipe grading. Your progress is backed up to your private iCloud account, so a new iPhone picks up where you left off. Wat Kham works on iPhone Duo, on both the outer and inner screens. Start free with the Thai Alphabet, Core Thai 1–100 and Numbers. Unlock the full library with a one-time purchase. No subscription.

Verdict
The clearest difference is ads: Sabai at none against Wat Kham's shown. On price, update cadence, in-app purchases and device support there is nothing between them.
