10,000 Hours vs Deep Hours

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. WHO IT'S FOR This app is for anyone working toward a long-term goal, including: • Language learners tracking study, immersion, and conversation practice • Artists and writers building a consistent creative practice • Students preparing for exams, certifications, or daily study habits • Developers, designers, and other professionals leveling up specific skills • Career changers building new expertise for a transition or promotion • Researchers, academics, and serious readers tracking deep work hours • Athletes and fitness enthusiasts counting training hours toward goals • Competitive players in chess, esports, or other strategy games • Performers — actors, dancers, comedians, public speakers — refining their craft • Musicians logging practice toward auditions, recitals, or personal mastery • Hobbyists going deep on photography, woodworking, cooking, or any craft • Anyone returning to a skill after a break and wanting to rebuild consistency TRACK YOUR SKILLS • Add new skills as you need, each with a custom name, icon, color, and description • Set targets at common milestones (100, 1,000, or 10,000 hours) or any number you choose • Add optional weekly and monthly goals • See an estimated completion date based on your current pace • Organize with priority levels, tags, and per-skill settings RUN SESSIONS • Start the built-in timer when you sit down to practice • Pause and resume as needed • Add quick notes mid-session to capture thoughts AFTER EACH SESSION • Rate how focused you felt • Add notes on what you worked on • See your progress update in real time • Continue with the same skill, switch to another, or stop UNDERSTAND YOUR PATTERNS • Activity heatmap covering the last 12 months • Daily, weekly, and monthly breakdowns • Per-skill trends, totals, and averages • Best time of day and most productive weekday • Focus quality distribution • Current streak and upcoming milestones HOME SCREEN WIDGETS • Multiple sizes for quick glances • Show today's total, current streak, or all your skills at once ADDITIONAL SETTINGS • Light and dark appearance • Optional daily reminders and streak alerts • Language selection • Data export (Pro) WORKS OFFLINE The app does not require an account, sign-in, or internet connection.
