FlowLock is an AI-powered desktop app that uses face recognition to know when you're at your desk, blocks distracting apps and websites during focus sessions, and gives you real analytics on your productive hours — no timers to press, no accounts to create, nothing stored in the cloud.
Most people have no idea how little they actually work. Here is what happens to almost everyone, every day.
You sit down to work but end up on social media for 45 minutes. You didn't decide to do that — it just happened. Again.
You have no idea how many hours you actually worked versus just sat at your desk. Was it 4 hours of real focus? 6? 1.5? You genuinely don't know.
Existing time trackers require you to manually start and stop them. You forget every time. Or you leave them running during your lunch break and the data is useless.
FlowLock solves all three. It automatically detects when you sit down, tracks your real desk time, blocks the apps that steal your attention, and gives you a weekly report so you can see exactly where your hours went — without touching a single button.
Four things happen automatically every time you sit down to work. You set it up once and forget it exists. Then read the data at the end of the week.
FlowLock detects your face via webcam the moment you sit at your desk and starts tracking automatically. There are no timers to press, no apps to open. The detection uses OpenCV's LBPH algorithm running entirely on your device — no images are stored, no cloud processing happens. You sit down, and FlowLock knows.
During active sessions, FlowLock enforces your custom block list. Distracting apps and websites are locked out for the duration of your focus block. You define the rules before you sit down, so the decision is made in advance — not in the moment when willpower is low.
No presence detected for 60 seconds? FlowLock pauses the session. Come back and it resumes. Break time is tracked separately. The result is an honest record of how long you were actually at your desk doing focused work — not just how long your computer was on.
Open the daily or weekly report and see your actual focus hours, break durations, and session history with timestamps. Identify your peak productivity windows. Track trends over weeks and months. Adjust your schedule based on data, not guesses.
Every feature in FlowLock is designed around one principle: honest data about your actual work time, with zero friction to collect it.
FlowLock uses OpenCV's LBPH algorithm running entirely on your device. No images are uploaded to any server — no cloud processing happens. It simply detects when you're present at your desk and starts your session automatically, then pauses the moment you step away. Detection latency is under 200ms with any standard laptop webcam.
Create custom block lists for apps and websites. FlowLock enforces them during focus sessions automatically. No willpower required — the decision is made before you sit down. You define the rules once, and they apply every session until you consciously change them.
See exactly how many focused hours you put in each day — not how long your computer was on, but how long you were actually present and working. Track trends over weeks and months. Identify your peak productivity windows and schedule your hardest work accordingly. Nothing exaggerated. Nothing rounded.
Configurable break intervals remind you to rest your eyes and move. Follows the Pomodoro technique or your own custom schedule. Every past session is logged with timestamps, duration, and distraction attempts so you can review exactly how a day went. Export data for personal tracking.
Activate deep work mode to block notifications, apps, and websites during your most important sessions. Only your tools. Only the work. FlowLock enforces the boundary so you don't have to rely on willpower in the moment.
Everything runs locally on your machine. No accounts required. No data leaves your computer. No subscription to cancel, no SaaS company holding your productivity data. You own your time tracking completely and permanently.
One-time purchase at $29.99. No subscription. No renewal email six months from now. Pay once, own the version you bought, and receive free updates for 12 months. Simple and honest — exactly like the rest of the product.
FlowLock is for anyone who needs honest data about where their time actually goes — and wants a tool that stays out of the way while providing it.
Know exactly how productive your work-from-home days really are. FlowLock gives you the honest data your manager can't see — and neither can you without it. Stop wondering if you put in a full day.
Stop losing editing hours to YouTube rabbit holes. FlowLock blocks the distractions that eat your creative time and tracks how many real hours you put into your content each week — so you can price your work accurately.
Track billable hours with proof of presence at your desk. FlowLock gives you the data to know exactly how long client work really took — and to justify your rate with confidence when clients question your invoice.
Protect your flow state from Slack notifications and context switches. FlowLock enforces your focus blocks and shows you how many real deep-work hours you actually got in a day versus shallow task time.
Study sessions with enforced focus and measured progress. Know how many hours you actually studied versus how long you had books open. Real data builds real habits and closes the gap between effort and results.
Most productivity tools require manual input, subscriptions, or cloud accounts. FlowLock is the only one that tracks your presence automatically and stays completely on your machine.
