About this app

Discover your best jawline.
JawMax is an intelligent facial fitness app that combines AI-powered facial analysis with personalized exercise training to help you sculpt a stronger jawline, improve facial balance, and enhance overall appearance.

🌐 AI Facial Analysis

Powered by Google’s Gemini 2.5-Flash AI, JawMax analyzes your facial structure using advanced computer vision and biomechanics. Each analysis reveals:

Breathing Type – Detects mouth vs. nose breathing patterns

Chin Projection – Measures forward jaw development (10–25 mm)

Face Fat Percentage – Estimates facial fat (0–30 %)

Gonial Angle – Calculates jaw angle in degrees (100°–140°)

Bone Mass Ratio – Evaluates facial skeletal density (0.5–1.2 scale)

Maxilla Growth – Measures upper jaw projection (10–25 mm)

Each scan includes metric scores, confidence ratings, and 4 personalized improvement tips, plus a complete jawline classification (Recessed / Normal / Protruded / Well-Defined).

💪 30-Day Training Programs

Transform your appearance with daily facial workouts—no equipment required.

3 targeted programs:

Jawline Program – Strengthen and define your jawline
