Letters, words and how they sound, on a guided path that reviews each one just before you would forget it. You start from zero.
No. Thai Trainer is built for complete beginners. It starts with the alphabet and builds from there, so you never need to know a single word before you begin.
Thai has 44 consonant letters. Two of them, ฃ (kho khuat) and ฅ (kho khon), fell out of everyday use in the 20th century, though they still turn up in older texts and in dictionaries. Thai Trainer teaches all 44, plus the vowels, diphthongs, tone marks and Thai numerals: 90 characters in total, each with recorded audio.
Most learners recognise all the consonants within 2 to 4 weeks of daily practice. It depends on how much time you put in: the spaced repetition system schedules each letter for the moment you are about to forget it, so short daily sessions go a long way.
Yes. Short, consistent sessions work better than long irregular ones, and that is exactly what the app is designed around. A ten-minute quiz covers everything due for review that day.
