Redo is the speaking-practice app that scores you and shows you exactly how to get better. Here's the idea: every day you record one short take, up to 60 seconds, answering a simple prompt. Redo transcribes it and scores how clearly you came across on a 0–1000 scale we call the Redo Index. Then it hands you the three specific things holding you back. Not vague advice, but the actual weak spots in this take. You redo the same topic aiming at those, get scored again, and watch the points stack up. That's the whole loop: Record → Feedback → Redo → Improve. Sixty seconds a day. WHY REDO IS DIFFERENT Most apps just tell you that you said "um" a lot. Redo tells you what to fix next — and lets you prove you fixed it. Because you redo the same prompt, your progress is measured against yourself: real, visible, undeniable. WHAT YOU GET • The Redo Index — one score out of 1000 that captures how clearly and confidently you spoke. • Six real skills, each scored with its own feedback: Structure, Conciseness, Confidence, Pronunciation, Filler Rate, and Pace. • Specific next steps — the top three things to work on, in plain language. • The redo — retry any topic targeting your weak spots and get re-scored blind, so the improvement is honest. • Daily 60 — a single 60-second rep a day. Small enough to keep, powerful enough to compound. • Streaks & history — a calendar of every session and a browser of past takes. Replay any recording, revisit any score. • Video or audio — practice with just your voice, or record video to watch your delivery. WHO IT'S FOR • Students prepping for presentations, interviews, and debates • Professionals who pitch, present, and lead meetings • Non-native English speakers building fluency and confidence • Anyone who rambles, rushes, or freezes up — and wants to fix it HOW IT WORKS 1.
