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. Your practice data lives on your device. No cloud account, no profile, no social feed. Daily reminders and language preferences are available if you want them. You can also export/import your data to a JSON file for backup/restore purposes.

Most time trackers are built for billing. Flows is built for understanding your day. Tap a card to start tracking. Tap another to switch. That's it. No projects, no timers to manage, no descriptions to fill in. Create your own flows: broad categories like Deep Work, Meetings, Admin, Resting, whatever matches how you actually spend your time. Flows records it and shows it back to you in a way that makes sense at a glance. Because work isn't just what was on screen. And your day is more than a timesheet. DRIFTING Not every minute gets deliberately assigned. Step away. Forget to tap. Take a break. Lose half an hour. Flows doesn't treat that as a gap or a failure. It becomes Drifting, a built-in flow that quietly catches the time you didn't claim. Move it later if you want. Leave it if it belongs there. Most trackers punish missing time. Flows treats it as part of the day. (One reason it sits well with ADHD brains, and anyone who forgets to tap.) SEE YOUR WHOLE DAY AT ONCE The day-bar is a coloured ribbon showing every minute of your day in the flow it belongs to. No spreadsheets. No reports to decode. Just the shape of the day, visible at a glance. MEET DROPLET Droplet is the small companion who lives in your timeline. No dashboards to read — Droplet notices the shape of your week and reflects it back in a sentence or two: which flows carried the days, when the drifting clustered, how the rhythm moved. Curious about something? Just ask. Ask Droplet answers from your own tracked time — "how much did I flow this week?", "where did my time go?" — in plain, warm language. Never a score. Never advice you didn't ask for. REFLECTIONS Zoom out to a week or a month and Flows shows its shape at a glance: a simple bar for each day, your flows laid out by rhythm, and a short reflection up top. Not "was this a good week?" Just "what kind of week was this?" FIX THINGS WITHOUT BREAKING ANYTHING Forgot to switch? Long-press a flow card to move time from one flow to another after the fact. Long-press any segment in the day-bar to see its history: what it was, what changed, and how it got there. Nothing is destructive. Corrections add clarity, they don't erase the past. FEATURES * One-tap tracking. Start and switch instantly. * Drifting. Built-in time for the moments you didn't claim. * The day-bar. See your whole day as a single timeline. * Droplet, a companion who reflects your week back to you. * Ask Droplet questions about your own time, in plain language. * Weekly and monthly Reflections that show the shape of your time. * Move time between flows after the fact. * Per-segment history and corrections. * Bridges. Flows asks what to do with gaps in your day. * A grace period for accidental taps. * No streaks. No guilt. Nothing to maintain. Ask Droplet and AI-written reflections need a device that supports Apple Intelligence. Everything else works on any supported device. WHAT FLOWS IS NOT * Not a productivity scoreboard. * Not a focus app that locks you out of things. * Not a billing tool with clients, invoices and hourly rates. * Not an automatic activity logger watching your screen. Flows is for people who finish the day and wonder where it went. A calmer way to track your time. Time flows. Know where.

Verdict
The clearest difference is ads: Flows at none against 10,000 Hours's shown. Flows also leads on update cadence (every 3 days vs every 5 months) and rating (5.0 vs 4.7). 10,000 Hours's advantage is ratings volume (3 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
