Two movements, minutes a day, coached rep by rep across 24 weeks. Leanness reveals the jaw — training defines it. The program requires a purchase.
Your jawline is trainable.
When you're already lean and the jaw still looks soft, it usually isn't genetics — it's habits. Chisel is a 24-week program built around two proven movements that train the muscles under your jaw, taught properly and coached rep by rep, in a few minutes a day.
Chisel is free to download. The 24-week program — every coached session, lesson and technique described below — requires a purchase: either a one-time purchase or an auto-renewing monthly subscription. Full pricing and terms are further down this page.
WHAT THE PROGRAM INCLUDES (requires purchase)
• A real progression — Foundation to Peak, paced by an engine that only moves you up when you're ready.
• Every session coached rep by rep, so you train with correct form instead of guessing.
• Every technique taught in full: what to do, why it works, the common mistake to avoid, and how it should feel.
• A daily "carry" — small habits you keep through the rest of the day.
• Progress photos that never leave your phone.
BUILT ON FORM, NOT GIMMICKS
Most people who try jaw exercises quit — not because the movements don't work, but because nobody taught them how to do them. Chisel is the coaching: clear cues, multiple camera angles, and a pacer that keeps you honest, so the work actually counts.
SAFETY FIRST
Before your first session, Chisel checks for signs of a jaw-joint (TMJ) problem and will hold you back if training could make it worse. This is a training program, not medical advice — if anything hurts, you stop.
PRIVATE BY DESIGN
No ads. No accounts. No data selling. Your progress and your photos stay on your device.
WHAT IT COSTS
The app is free to download. Access to the program requires one of two purchases, both unlocking exactly the same content:
• The Program — $24.99, a one-time purchase. Everything, through to completion. No subscription.
• Monthly — $4.99 per month, an auto-renewing subscription. Same everything, cancel any time. The program runs about six months.
Prices are in USD; your local App Store price applies and is shown in the app before you buy.
Payment is charged to your Apple ID at confirmation of purchase. A monthly subscription renews automatically at $4.99 per month unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel a subscription in your Apple ID account settings after purchase.
