About

Mandible

Mandible: TMJ relief is a six-week program for jaw pain, tension, and TMJ troubleβ€”including the clenching and teeth grinding that often come with it. A few small things each day, plus a record of how your jaw feels over time, so you can tell what's actually helping. Most days take about ten minutes: a couple of guided exercises, a short audio session, and a quick check-in. On a bad day, reach for the flare-up toolkit instead. WHAT'S INSIDE - Daily jaw exercises β€” Guided routines based on the Rocabado protocol, with a timer and clear cues, so you're never guessing how long to hold or how many to do. - Guided audio β€” Hypnotherapy and relaxation sessions made for jaw and facial tension. Add a nature soundscape if you like: ocean, rain, or forest. - Flare-up toolkit β€” Quick relief for the rough moments and clenching episodes: a 30-second jaw drop, a heat-and-cold timer, and a muscle-release exercise. - Symptom journal β€” Log pain, tightness, grinding, stress, and triggers in a few taps. After a couple of weeks, your patterns show up on their own. - Progress and reminders β€” Keep a streak, mark sessions done, and set a daily reminder that fits your routine. - Weekly lessons β€” Short, plain-language readings on how the jaw, stress, sleep, and bruxism connect, and why the exercises work. - Shareable report β€” Turn your history into a simple summary for your dentist or doctor. The whole thing is built around showing up. A short routine you keep does more than a long one you abandon, so the daily habit is kept small on purpose. SUBSCRIPTION Mandible offers two options: Weekly ($9.99) and Yearly ($49.99). Payment is charged to your Apple ID at purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. There is a free 3 day trial. Mandible is meant for education and general wellness. It is not medical advice and does not replace care from a qualified professional. If your symptoms are severe or getting worse, see a doctor or dentist. Terms of Use: https://www.lunairelabs.com/MandibleTerms.html Privacy Policy: https://www.lunairelabs.com/MandiblePrivacy.html
