Recall vs ShadowingExplore

You know the word "ubiquitous." You understand it when you read it. But when was the last time you actually used it in a sentence? That gap between words you recognize and words you produce is real. Recall was built to close it. WHY RECOGNITION IS NOT ENOUGH Most vocabulary apps test whether you recognize a word — flip a card, pick the right answer, move on. But research shows recognition and production are different skills. You can "know" thousands of words and still freeze when trying to use them in speech or writing. Recall replaces passive flashcard flipping with active production. You explain meanings in your own words. You create sentences. An AI evaluator scores your response and helps you improve. HOW IT WORKS 1. A word appears from your vocabulary 2. Explain the meaning or use it in a sentence 3. AI evaluates your response on a 0-5 scale 4. Smart spaced repetition brings it back at the right time Score a 5? You won't see it for weeks. Score a 2? It comes back tomorrow. The algorithm adapts to your actual production ability, not your self-assessment. PRACTICE MODES Explain Meaning — Describe what a word means in your own words. AI checks whether you captured the core concept and suggests improvements. Use in Sentence — Create a natural sentence using the word in context. AI evaluates grammar, word usage, and naturalness.

Understand native English. Then speak it. ShadowingExplore turns shadowing — repeating a native speaker right after you hear them — into practice anyone can keep up with. Built for the moments when: "They talk too fast for my mouth to keep up." "I just mumble along and call it done." "I can't tell how my pronunciation differs from theirs." THREE STEPS, THAT'S IT 1. Listen — follow along with karaoke-style subtitles that light up as each word is spoken 2. Shadow — with earphones in, speak right behind the speaker while the app records you 3. Compare — hear the speaker in one ear and yourself in the other, at the same time SEE HOW YOU SOUND Your pitch is drawn on the same graph as the speaker's, so you can spot exactly where your intonation drifts. Timing between your recording and the original is aligned automatically for an accurate comparison. After every take you get a sync score against the original. DRILL ONE SENTENCE AT A TIME Audio is split into sentences automatically. Repeat just the lines you can't catch, or select any words to save them as your own clip. START SLOW Slow playback from 0.6x to 1.0x, jump back or forward 0.5 seconds, and loop until you get it. Turn subtitles off when you're ready to train your ears alone. BUILT TO STICK A daily goal ring, streaks and your week at a glance on the home screen keep you coming back.
