Bruxism affects up to 31% of adults. Jaw clenching, teeth grinding, and TMJ tension often go unnoticed until the damage is done: headaches, worn enamel, chronic pain, disrupted sleep. Masseter is a science-backed awareness tool that uses Ecological Momentary Assessment (EMA) — the gold standard in behavioral research — to help you catch clenching in real time, build mindful habits, and reduce jaw tension over time. --- HOW IT WORKS - SMART REMINDERS — Random check-ins throughout your active hours. No predictable patterns. Based on the same stratified-random sampling used in clinical studies. - ONE-TAP CHECK-IN — When prompted, simply log whether you're Relaxed, In Contact, Clenching, or Bracing. Takes 2 seconds. - TENSION INDEX — See your daily jaw tension score on a beautiful radial gauge.

Discover your personal triggers. --- INSIGHTS THAT MATTER - Hourly tension heatmaps — see when you clench most - Day-of-week analysis — discover your worst days - Context correlations — find which activities drive tension - 30-day trend charts — watch your progress unfold - Peak tension alerts — identify your danger zones --- LEARN & UNDERSTAND 4 in-depth articles written in plain language: - The Masseter Muscle — physiology of jaw tension - The Spot Technique — awareness building method - Relief Protocol — acute pain management - Sleep Hygiene — nighttime bruxism strategies --- DESIGNED FOR YOUR LIFE - Apple Watch — check in from your wrist - Home Screen Widget — one-tap logging without opening the app - Quick Actions — fast shortcuts for instant check-ins - Lock Screen Notifications — respond directly from the notification - iCloud Sync — seamless data across all your devices - Baseline Pain Assessment — track jaw, temple, and neck pain over time --- PRIVACY FIRST Your jaw data stays on YOUR device.
