Masseter: Jaw Clench & TMJ

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.
