10,000 Hours - Mastery Tracker is a practice tracker for people serious about getting better at something — whether that's playing guitar, learning a language, writing fiction, coding, drawing, chess, or any skill that rewards sustained effort. The premise is straightforward. Pick what you want to improve at, decide how many hours you want to invest, and log your practice sessions as you go. Over weeks and months, you'll see your time accumulate, your patterns emerge, and your progress build. This isn't a habit tracker or a to-do list. It's a focused tool for one thing: helping you keep showing up for the work that matters to you, and giving you a clear picture of what you've done.
