Flash is a mobile language-learning app that helps you acquire vocabulary and sentence patterns through short, adaptive sessions — so you retain what you practice.
Join the Android closed beta · Limited tester spots
Traditional study methods — word lists, flashcard apps, grammar drills — demand too much time and produce too little engagement. Most learners stop before real retention happens.
Sessions are short and immediate. No setup, no long lessons to load. You practice in minutes, not hours.
Adaptive review targets the words you need most. Progress does not rely on discipline alone — the system guides the loop.
Flash is built around vocabulary acquisition and sentence pattern recognition — the two things that move real language ability forward.
Train in short, focused bursts.
Fast responses turn into momentum.
Hard words return. Mastered words fade.
Leaderboards are optional, not required.
Live and being tested on Android.
English and Spanish available. More languages planned.
Core learning, review, streak, and progress systems are live and improving.
