Unclench
Catch your jaw clenching now — not in an exercise session later
A running check-in that asks, in the middle of your workday, whether your teeth are touching. Answer, run the five-second reset drill, and a heatmap shows the exact hour you clench most. Six TMJ stretches included, free, nothing to install.

What you can do in Unclench on the web
The check-in, not a programme
Every 10, 20, 30 or 45 minutes inside your active hours this tab chimes and asks one question: are your teeth touching right now? Clenched, mid or relaxed — one tap.
The five-second reset drill
After every answer: tongue on the roof of your mouth, teeth apart, lips together, held for a timed count. That is the thing that retrains the habit.
Your trigger window, found
An hour-by-weekday heatmap plus a clench-rate-by-hour chart name the window where your teeth are together most — 11am on calls, or after 4pm.
Six clinician-recommended TMJ stretches
Resisted opening, both goldfish exercises, chin tucks, side-to-side jaw and resisted closing — full instructions and a hold-timer ring for each.
Night grinding log
Record episodes and hours for each night so daytime clenching and night-time bruxism sit side by side, with a bar chart across your recent nights.
No streak, no guilt, no account
Miss a ping and nothing breaks. Your log stays in this browser and exports to CSV for a dentist or physio.

Try it with sample data: Loads two weeks of check-ins — seven a day on weekdays, three at weekends — weighted so the late-morning hours read clenched and the late afternoon relaxes, plus five nights of grinding episodes. You can start fresh at any time.

Where is my data stored?+
