## What is WuDuck?

WuDuck - Stress-Free Weight Loss Buddy

"WuDuck" sounds like "stress-free" in Chinese. We believe weight loss shouldn't be about pain and anxiety. WuDuck is a cartoon duck buddy that tracks your daily balance across four dimensions — water, exercise, sleep, and weight — helping you build lasting healthy habits for sustainable weight loss without rebound.

Auto-Sync from HealthKit, No Manual Logging
Stop manually entering every meal. WuDuck automatically syncs your diet, water, exercise, and sleep data from HealthKit. Data from apps like Mint Health, Apple Health, and Keep flows into WuDuck automatically, saving you tedious manual entry.

Four-Dimension Balance Tracking
Proper diet, moderate exercise, adequate water, sufficient sleep — four dimensions make up your daily health balance. Simple, intuitive tracking shows your day at a glance.

Weekly & Monthly Reports
Visualize your balance trends week by week and month by month. See the power of consistency at a glance — every dimension's change is right there.

Colorful Widgets, Duck Buddy Always With You
4 beautiful home screen widget styles with rich cartoon duck illustrations accompany you through your weight loss journey. iOS 17+ users can use one-tap Quick Check-in Widget to check in directly from Lock Screen or Home Screen — no need to open the app.

Theme Customization
Four color themes to match your style. Pick the one that fits your vibe and let your duck buddy check in with you in style.

Streaks & Milestones
Hit 7, 14, 30, 90, 180, 365-day streak milestones to unlock exclusive badges. Every persistence is witnessed by your duck buddy.

Streak Share Cards
Turn streak milestones and four-dimension status into shareable cards. Post to socials and let friends cheer you on.

Weight Trend Visualization
45-day weight curve and body fat trend, scientifically track your progress. Not about quick drops, but long-term trends.

Evidence-based Health Philosophy
WuDuck promotes evidence-based nutrition: proper diet (no starving), moderate exercise (no extreme workouts), adequate water (as needed), sufficient sleep (regular schedule). Build lasting habits for sustainable weight loss.

Who It's For:
- People who want to lose weight without calorie-counting anxiety
