Built for the fight against snoozing
Every feature solves one problem: a sleep-drunk brain in soft focus, trying to cheat its way back to unconsciousness. We’ve made that difficult — and turned the five minutes it buys into a word learned.
Alarm-based learning
Set alarms that won’t dismiss until you answer a vocabulary question. Choose your time, repeat days, and difficulty per alarm.
SM-2 spaced repetition
The algorithm behind Anki. Words you struggle with come back sooner; mastered words fade into longer review intervals.
Thirteen learning languages
Mandarin Chinese, Japanese, Korean, Portuguese, Spanish, French, German, Italian, Russian, Hindi, Arabic, Dutch, and Turkish. Free covers one at a time; Pro opens all of them at once.
Custom word lists (Pro)
Build lists for travel, an exam, or a show you’re watching. Assign a list to an alarm and drill exactly what you need.
Adaptive difficulty
Quizzes adapt in real time. Too many wrong and the difficulty drops; on a roll and it climbs. Hints surface when you’re stuck.
Five quiz types
Script-to-meaning, script-to-romanization, romanization-to-script, meaning-to-script, and romanization-to-meaning — adapted to your language.
Weak-word report (Pro)
The words you keep getting wrong, ranked, so a spare five minutes goes where it actually helps.
Progress dashboard
Accuracy by level, words seen, words mastered, and quiz history. With Pro, mobile and web stay in sync.
Daily streaks
Build momentum with day streaks. Complete one quiz a day to keep it alive — miss a day and it resets.
Guided onboarding
New users pick a language and level on first launch, so the app personalizes from the very first morning.
