tenthousand is a focused practice tracker for people who want to improve a skill over time. The idea behind the app is simple: meaningful progress usually comes from consistent effort, repeated over a long period. tenthousand helps you make that effort visible. Whether you are learning design, coding, writing, music, language, sport, or any other skill, the app gives you a clear place to track the hours you invest and the milestones you reach along the way. This is not a social app and it is not built around noise, streak pressure, or distractions. It is designed to help you stay honest about practice, build momentum, and see progress accumulate session by session. With tenthousand, you can create the skills you want to develop and track them individually. Each skill has its own progress, time history, and milestones, so you can manage multiple long-term goals in one place without mixing them together. Key features: β’ Create custom skills : Add the skills or disciplines you want to improve, from professional goals to creative work and personal learning. β’ Track live practice with a timer: Start a timer when you begin a focused session and stop it when you finish. The app records the time for you. β’ Log time manually: Add past practice manually, including larger backfilled hour totals if you started tracking after already investing significant time. β’ Add milestones: Break a long journey into concrete checkpoints. Set your own milestones for each skill and track progress toward them over time. β’ View your logged practice clearly: See your total practice time and review recent sessions for each skill in a clean, simple interface. β’ Optional reminder notifications: If you leave a timer running, the app can send local reminders after 30 minutes, 1 hour, and then hourly, so you can confirm whether you are still working or forgot to stop it. β’ Simple settings and local control: Notification reminders can be turned on or off inside the app. tenthousand is built for people who take long-term improvement seriously. It works well for students, makers, developers, writers, musicians, athletes, language learners, and anyone who wants to stay consistent with deliberate practice. The app is inspired by the widely discussed idea that sustained practice over time can lead to very high levels of performance. At the same time, it keeps the concept grounded. Progress is personal, and expertise is never guaranteed by a number alone. What matters is showing up, practicing with intention, and continuing over time. That is the role of tenthousand: to help you measure the work, respect the process, and stay engaged with the skills that matter to you. Privacy and simplicity are part of the product. Your data is stored locally on your device. No account is required. If you want a cleaner view of your effort and a calmer way to track skill development, tenthousand gives you the essentials without adding unnecessary complexity.
