Duchenne is your smile confidence coach, the app that trains the genuine, eye-engaging smile you need for interviews, weddings, and every photo that matters.
5 minutes of daily practice. Real change in two weeks.
Powered by TrueDepth, your iPhone's face-mapping camera, Duchenne gives you real-time feedback on the actual face muscles behind a real smile, on-device, with nothing ever uploaded.
WHAT'S INSIDE
DAILY CHALLENGES
A short, guided session every day. Each one builds on the last, training the small face muscles that turn a posed smile into a genuine one. Five minutes is enough.
QUICK TRAIN
The five-second warm-up before the moment that matters. Pre-interview. Pre-photo. Pre-presentation. Pre-first-date. A focused session that gets your face ready when there's no time to waste.
GALLERY
Capture a photo each day and watch your progress over weeks, not minutes. The change is real, and seeing it is the motivation that keeps you going. See the change, week by week.
ACHIEVEMENTS
Streaks, milestones, and quietly satisfying wins that turn practice into a habit you actually look forward to.
EVENT MODE
This is the feature that changes everything. Add the wedding, the interview, the photoshoot, the speech, and Duchenne ramps up your training so you walk in ready. The closer the date, the more focused the practice.
WHO IT'S FOR
• Brides and grooms preparing for wedding photos they'll keep forever
• Job candidates walking into final-round interviews, headshot prep and interview prep in one
• Content creators and anyone who lives on camera
• Public speakers, presenters, and anyone with a stage moment ahead
• Actors, models, and broadcasters refining their professional range
• Anyone who finds smiling on command awkward, stiff, or unnatural
WHY IT WORKS
A genuine smile is a learnable skill, not a fixed trait. The Duchenne smile activates specific face muscles around the eyes, and like any muscle pattern, it responds to deliberate practice. Duchenne is built around short, repeatable training that builds the muscle memory of a real smile.
Unlike voice coaches that send audio to the cloud, Duchenne processes your face entirely on-device. Real-time, specific muscle feedback, not vague tips, no upload delays, no failed analyses.
PRIVACY FIRST
Your photos stay on your device. Camera and photo permissions are used only to capture and review your own progress. We don't upload your face. We don't analyze your face on our servers. We don't share your data. Ever.
FREE TO START
Duchenne is free to download and free to keep using. The free version includes two daily sessions, a rotating challenge, a 30-day gallery, and one upcoming event, enough to build the habit and feel the difference.
