Read full descriptionHide full description
Mastery Timer turns the time you spend getting good at something into visible progress. Pick the skills you want to master. Writing, reading, an instrument, a language, a sport, meditation, anything. Give each one a daily goal, and fill its bar a little more every day. Every minute counts toward the bigger picture: the path to 10,000 hours of mastery. As your hours add up you rise through 25 ranks, from your very first session to true mastery, and the app tells you something new at every single hour. Not only at the milestones, every hour. What is shifting in your craft, what you have unlocked, how far you have come. No points to lose. No guilt. No streaks that punish you for a missed day. Lifetime hours and ranks only ever go up. If you skip a day, a streak simply starts again, quietly. Mastery Timer is built for years of use, not for a quick hit. Features - Create as many skills as you want, each with its own daily goal - A clean bar you fill each day, with a gentle gong when you reach your goal - A lifetime mastery view: your hours, your current rank, and encouragement that changes every hour - Tailored progress for each kind of skill, from writing to music to fitness - Fully offline and private. Your practice stays on your device. No account, no data collected - A calm, distraction free design The work is the point. Mastery Timer just makes the hours add up where you can see them.
