ShadowFlow vs Ascent

ShadowFlow turns YouTube videos into living language lessons. ■ Watch with karaoke subtitles Subtitles highlight word by word in sync with the video, so you never lose your place. Tap any line to jump to that scene. ■ Tap any word you don't know The dictionary opens instantly. Save words with one tap — review them as flashcards, hear the pronunciation, and jump back to the exact scene where each word appeared. ■ Practice speaking with shadowing (MAX) Record your own voice line by line and compare with the original. With headphones, your voice plays in the right ear and the original in the left. Pronunciation scoring shows exactly which words didn't come through, and rhythm bars compare your timing with the original. ■ A shared pool of subtitles (Pro) Subtitles created by users are shared in a pool — once someone transcribes and fixes a video, everyone can learn from it. New subtitles are created on the desktop web version (kotomori.app/shadowflow). ■ Plans - Free: watch subtitles you created, word list - Pro: unlimited access to the shared subtitle pool + folders - MAX: everything in Pro + shadowing practice Available in English, Japanese, Spanish, Simplified Chinese, Korean, French, and German. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in your App Store account settings.

Ascent is the whole of Algebra 1, played as one long climb up Everest. Twelve legs, one skill at a time, from signed numbers at the trailhead to radicals on summit day. HOW IT CLIMBS An adaptive guide keeps you on exactly one new skill at a time, mixed with review of the ground you already hold. Equations rewrite themselves step by step as you choose the moves. When you are stuck, the radio gives hints that teach the next step, never just the answer. Every correct answer banks real altitude on the mountain. THE ROUTE Foundations. The language of algebra. Linear equations. Inequalities. Functions. Linear functions and data. Systems of equations. Exponents and growth. Polynomials. Factoring. Quadratic equations. Radicals and Summit Day. Twelve units, the full course.
