Tension headaches and cervicogenic headaches often start with tightness in the jaw and neck — muscles you may not even realize you're clenching. Release guides you through a short daily stretching routine designed to help relieve that tension before it becomes a headache. Your jaw and neck will thank you! WHAT YOU GET • 8 guided exercises targeting the jaw (TMJ) and neck, based on commonly recommended physical therapy stretches • Step-by-step timer with animated illustrations for each exercise • A routine that takes less than 10 minutes a day • Streak tracking and a 7-day habit tracker to help you stay consistent • Morning and evening reminders so you don't forget • Full customization — adjust reps, hold times, or turn individual exercises on or off DESIGNED WITH YOUR PRIVACY IN MIND Release does not ask for your name, email, or any personal information. There is no account to create. No data leaves your phone — ever. The app works entirely offline with no internet connection required. The only optional permission is notifications, and only if you choose to enable reminders. COMPLETELY FREE There are no in-app purchases, no premium tier, no ads, and no subscriptions. Every feature is available from the moment you download it. IMPORTANT NOTE The exercises in this app are based on commonly recommended stretches for jaw and neck tension. They are not a substitute for professional medical advice. If you experience pain, dizziness, or unusual symptoms during any exercise, stop immediately and consult a healthcare provider.

Mandible: TMJ relief is a six-week program for jaw pain, tension, and TMJ trouble—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 — 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 — Hypnotherapy and relaxation sessions made for jaw and facial tension. Add a nature soundscape if you like: ocean, rain, or forest. - Flare-up toolkit — 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 — 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 — Keep a streak, mark sessions done, and set a daily reminder that fits your routine. - Weekly lessons — Short, plain-language readings on how the jaw, stress, sleep, and bruxism connect, and why the exercises work. - Shareable report — 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

Verdict
The clearest difference is in-app purchases: Release at none against Mandible's 2. Release also leads on update cadence (every 6 days vs fortnightly). Mandible's advantage is iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
