The fastest way to build a Chinese vocabulary that actually lasts! Fluo combines spaced repetition — the most effective memory technique ever studied — with AI-generated sentences tailored to your exact level. No flashcard grinding. No generic lessons. Every word you learn stays learned, because every review is timed perfectly and every sentence is built just for you. Adaptive learning Every sentence adapts to where you are right now. Words you know appear alongside words you're learning, so you're always challenged but never overwhelmed. As you improve, your sentences evolve with you — and you can listen to native audio for every single one. Learn what you actually care about Pick your topic — food, travel, business, health, or anything you type in — and practice sentences built around the vocabulary that matters to you. No more memorizing words you'll never use. Every word tracked, nothing left to chance Tap any word to see how well you remember it. Fluo tracks your recall for every single word and schedules reviews at the optimal time. Words you struggle with come back sooner. Words you know well get spaced out. You just practice — the system handles the rest. Test yourself in both directions See Chinese and recall the meaning. See English and produce the Chinese. Fluo's active and passive recall modes push you from recognition to real production — the difference between understanding a menu and ordering from it.

Six cognitive tests, adapted into five minute workouts. No account. Nothing leaves your phone. Works with no signal. Each exercise adjusts to how you did last time, so it stays hard enough to be worth doing. A session runs five to twenty minutes, and a short calibration at the start finds your working level in each one. THE SIX Reaction Control (Go/No-Go test), for response inhibition Colour Conflict (Stroop test), for selective attention Memory Match (N-back test), for working memory Spatial Sequence (Corsi block test), for visual-spatial memory Rule Switch (task switching test), for mental flexibility Number Sprint (mental arithmetic), for speed SCORED AGAINST YOU Your results are compared with your own history. There is no global score, no percentile and no leaderboard. READ WHAT YOU ARE DOING Every exercise has a page with the rule written out and a live preview, plus six written guides on the Stroop effect, the n-back task, working memory, the five minute workout, simple maths, and whether brain training works at all. PRIVATE BY DEFAULT No account, no sign-in, no tracking, and nothing is sent to a server. The app works with no network connection at all. This app is not a medical device. It does not diagnose, treat or prevent any condition, and it does not measure intelligence.
