Every hour counts.

10,000 squares. One for every hour you show up.

Choose what you’re practicing, enter the hours you completed, and press Enter. Or click the grid to count one hour at a time. Click your total to correct it. Sign in with Google to keep your records across devices.

The 10,000-hour idea is a useful reminder of sustained effort, not a guarantee of expertise. Practice quality, feedback, and the skill itself matter. The completion certificate celebrates your self-reported commitment.

No timer. No leaderboard. No ads. Just a place to make your effort visible.
