Unclench

100% Free | No Ads

Bruxism affects more than 1 in 5 people globally. Chronic jaw tension can lead to headaches, neck pain, and sleep disturbances. Regular check‑ins can help you spot and manage these issues early. Unclench nudges you at random times throughout the day to check in on your jaw — a technique called ecological momentary assessment (EMA). EMA keeps logs honest and low‑effort. Log how your jaw feels in one tap via the widget or by long‑pressing the notification, or with the Apple Watch app and its complications. Export your data any time from settings, and optionally sync to iCloud. Your data can sync between your phone and watch with or without iCloud.
