Everything you need to stay in flow
Six tools, one calm dashboard. No tabs, no chaos — just the things that matter when you're trying to think.
Deep-work analytics
See exactly when you focus best, what kills your sessions, and how your attention trends week over week.
Distraction blocker
Site & app blocking that activates the moment your timer starts and never gets in the way.
Calendar sync
Drop focus blocks into Google or Outlook calendar so colleagues know not to interrupt.
Team mode
Synchronize focus blocks across the team. Async standups, async respect, async rituals.
Weekly reports
A short, honest email every Sunday: what you did, what you didn't, and one tiny experiment for next week.
Three steps. No new habits to learn.
You already know how to focus. Lumen just gets out of the way and counts what counts.

Review honestly
A weekly digest tells you when you focused best — and gently nudges you to repeat what worked.
Inside Lumen
Numbers that tell you something.
Most productivity apps drown you in metrics. Lumen surfaces three: when you actually focused, where your attention leaks, and one experiment to try next week.
- Live focus index — quality of attention, not just minutes spent.
- Distraction heatmap — see exactly which apps cost you the most flow.
- Streak protection — one bad day doesn't reset your momentum.
- Privacy-first — your data never leaves your device unless you say so.
