Communication Mirror turns your iPhone into a private practice room for speaking. Record yourself talking, then review the playback the way an audience actually experiences you — what you said, how you sounded, and how you moved — so you can fix one habit at a time and watch it stick. WHY IT MATTERS You rarely get to see yourself the way other people do. Communication Mirror gives you that mirror. Instead of guessing whether you rambled, slouched, or filled the silence with "um," you watch the evidence and decide for yourself what to keep and what to change. Reading your own words back is often the moment it clicks: the pause you did not notice, the point you made twice, the sentence that landed. Most speaking advice is vague and overwhelming — work on everything at once and you change nothing. Communication Mirror flips that. You choose one focus, practice it across a few takes, and watch a single habit actually move. Whether you are getting ready for a presentation, an interview, a difficult conversation, or just want to sound more like yourself, the loop is the same: record, review, refine. HOW IT WORKS Record a short video of yourself speaking. While you record, on-device body-pose detection follows your posture and gestures, and a thumbs up gesture lets you flag a moment in real time so you can jump straight back to it later. Your speech is transcribed on device, so you can read back exactly what you said, word for word. Then you run a structured self-review across three lenses. Listen to how you sounded. Watch how you looked. Read the transcript of what you actually said. As you go, you tag the points you want to work on — the rushed opening, the fidget, the filler word — and turn them into something you can practice. Pick one focus to improve at a time, record again, and let your streak and progress stats keep you honest. Set a gentle reminder and practice becomes a habit instead of a someday. WHAT YOU GET • Video recordings you can replay and review whenever you want • On-device pose tracking and a thumbs-up gesture to mark key moments • On-device transcription so you can read back every word • A guided self-review for auditory, visual, and transcript feedback • One focus at a time, with streaks, progress stats, and reminder notifications PRIVATE BY DESIGN Your practice is nobody else's business. Recording, pose detection, gesture detection, and transcription all run on your device. There is no account to create and no sign-in.
