Master anything.
10,000 hours at a time.
TenKHours is a deliberate-practice tracker for the people who actually keep at it. Time your sessions, cross real milestones, and watch the hours compound into mastery.
Swift & Concurrency
Mastery isn't a moment.
It's a slow, deliberate stack of hours.
The research is consistent: it takes roughly ten thousand hours of focused, deliberate practice to reach world-class command of a complex skill. TenKHours doesn't promise shortcuts. It promises a tool worthy of the effort.
A tool that takes practice as seriously as you do.
Every feature exists because something gets in the way of consistent deliberate practice — and we built the antidote.
Sessions & Timer
One-tap to start. Pomodoro blocks built in. Live Activity on the Lock Screen so you never lose track of a session.
Mastery Roadmap
Twelve milestones from your first hour through 10,000. Each one earned, never granted. Achievement chips that genuinely feel good.
Insights
Weekly review, peak-hour heatmaps, focus scoring, and a Year in Review that's worth waiting all year for.
AI Coach
On-device practice plans tuned to your skill, your energy, and what you actually got done last week. Quiet, private, useful.
Streaks & Achievements
Forgiving streaks that respect rest days. Achievements that mark genuine moments — not engagement bait.
Everywhere you are
Apple Watch for hands-free sessions. Widgets for at-a-glance progress. Siri Shortcuts so "Start Swift" actually starts Swift.
A timer worthy of the work itself.
The session screen is the one you'll look at most. So we made it the one we obsessed over most — a ring that breathes, numbers you can read across the room, and zero chrome between you and the work.
Twelve milestones. Each one earned.
Every threshold is a real moment in mastery — Apprentice, Journeyman, Master, Grandmaster. We don't hand them out. You cross them.
Every screen you'll live in.
From the Mastery Roadmap to the Year in Review, these are the screens you'll see every day. No mockups.
The whole climb at a glance — your current tier, your next threshold, your distance to ten thousand.
Your year of practice, on one page. Hours, peak hours, breakthroughs, and the milestones you crossed.
The patterns of your best work, made visible.
See when you ship, when you fade, and when the streak is real. Insights that give you a reason to pick the right hour of the day — not a reason to feel bad about the wrong one.
The kind of tool we always wished existed.
Finally, a tracker that doesn't treat me like I need a sticker. The Year in Review made me cry on January 1st.
I've used eight habit apps. This is the first one I haven't deleted within a week. The milestones feel earned.
The Live Activity on the Lock Screen is dangerously good. I keep practicing because the timer is right there.
Ten thousand hours starts with one session.
Free to start. Pro when you're ready. Built by an indie iOS developer who's tracking their own 10K right alongside you.
