Notch: GTG Watch Timer

Tap. Hang. Tap. The Watch-first Grease the Groove timer. Build strength in 30-second sets throughout your day. No subscription. $4.99 unlocks history.

Stop forgetting to practice. Start notching reps.

Notch is the Watch-first app built for Grease the Groove training, the proven method of doing small sets throughout your day to build strength without burning out.

Raise your wrist. Tap. Hang. Tap when done. That's it.

WHAT IS GREASE THE GROOVE?

Coined by strength coach Pavel Tsatsouline, Grease the Groove (GTG) means doing frequent, sub-maximal sets of one movement throughout the day. Never to failure, always fresh. It's how you go from 3 pull-ups to 15. It's how desk workers build dead hang strength into their commute. It's how you get stronger without a gym membership.

The catch is you have to remember to do the sets. That's where Notch comes in.

PRIVACY

Your sets, heart rate samples, and streaks live in a local database on your devices. No third-party analytics. No ad networks. No tracking SDKs. The watch reads heart rate via HealthKit only while a hold timer is running. The iPhone can save each finished set to Apple Health as a workout if you allow it.

WHO IT'S FOR

• Climbers training dead hangs between meetings
• Desk workers building plank time
• Calisthenics folks running pull-up GTG protocols
• Anyone building a strength habit in 30 seconds at a time
• People tired of fitness apps that bury logging behind four taps

If you've ever stuck a pull-up bar in a doorway and forgotten about it for three weeks, Notch is for you.

Built by one developer. Watch-first.
