Released May 25, 2026
Auth with Firebase

Sign in with email + password or Continue with Google — your XP and saved vocabulary sync with the web app.

AI fill new vocab

Type just the Thai, English or romanization in the Add-word sheet, tap AI fill, and the rest — pronunciation, category, an example sentence and its translation — gets completed for you. 5 generations per day per learner; your typed values are never overwritten.

Redesigned navigation

Five clearer tabs: Home, Words, Learn, Practice and Profile — so it's obvious where to check progress, build words, learn the script and practice.

Learn & Words

Consonants, Vowels and Tones live under Learn; Vocabulary and Classifiers under Words. Every screen has a Reference view plus drills that earn XP as you practice.

Practice modes

Flashcards, Quiz, Match, Memory, Vocab quiz, Vocab match, Sort, Shoot and Draw — the same practice modes as the web, with XP for correct answers.

Read + dictionary lookup

Stories, fables, dialogs and recipes with end-of-reading comprehension quizzes. Tap any Thai word to see its translation, and add unknown words to your personal vocab from the popover.

Word of the Day reminders

Opt in from your Profile to get a daily Word-of-the-Day notification at the hour you pick, so a little Thai lands in your pocket every day.

Theme switcher + milestone timeline

Profile tab now has a pink ↔ blue theme picker and a milestone timeline showing what unlocks at every XP threshold.

Persistent navigation

The Home / Learn / Words / Practice / Profile tab bar stays visible on every sub-screen, so you can hop between sections without backing out.

Beta heads-up. This is a self-signed beta build distributed outside Google Play. Android will warn you about "unknown sources" — that's normal for sideloading. Your phone's anti-malware may also flag it on first install; the file you're downloading is signed with the sabaisabai beta keystore and served directly from this site.
iPhone? iOS builds require an Apple Developer account and store submission, which isn't set up yet. For now use the web app on Mobile Safari — it's mostly feature-parity.
