About
Your jaw works harder than you think — and Masseter helps you notice.
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. Track progress over days and weeks.
- CONTEXT TAGS — Tag what you're doing when you clench (work, commute, sleep). 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
