Cal Newport was right - deep work is the superpower of the knowledge economy. But most people don't know how many deep work hours they actually get. This tracker measures it, grows it, and protects it.
No ads. No data harvesting. No dark patterns. No notifications begging you back. Built to give you your time back.
Why deep work is harder than you think
The gap between busy and productive is enormous
You think you work 8 hours but deep work is maybe 3
Meetings, Slack, emails, context switching - they eat your day alive. When you start tracking actual focused sessions, the real number is always lower than expected. That awareness changes everything.
You don't know when your peak hours are
Everyone has a biological window for their best work. The focus heatmap reveals yours - morning, afternoon, or night. Stop scheduling meetings during your golden hours.
Shallow work keeps winning over deep work
Without tracking, your calendar fills with low-value tasks that feel urgent. When deep work sessions are visible and measured, they become the priority. What gets tracked gets protected.

How to grow your deep work hours
Cal Newport's framework is straightforward: deep work is rare, valuable, and produces real output. Most people overestimate how much they do. Here's how to find out where you actually stand - and grow the number.
1
Find your peak focus window
Track a few weeks honestly. The focus heatmap will show when you actually do your best work - usually a 2-4 hour window that's narrower than you think. For most knowledge workers it's mid-morning. Once you see yours, the rest of the plan writes itself.
2
Protect that window like it's the job
No meetings, no Slack, no email during peak hours. Put it on the calendar as "deep work" and treat it as immovable. This is the single highest-leverage scheduling change you can make - and the hardest to actually do.
3
Start with 25-minute sessions, work up to 90
Deep work is a muscle. Don't try for 4-hour blocks on day one - you'll burn out and quit. 25/5 pomodoros build the habit. Over weeks, stretch to 50/10. Eventually 90-minute uninterrupted blocks become possible.
4
Measure everything - what gets tracked grows
Tag every session by category (Deep Work vs Shallow Work, or per-project). The weekly report makes the ratio visible. Without measurement, shallow work wins by default because it feels urgent. Deep work needs to be defended.
Pricing
Start free, upgrade when you're ready
The core timer and habit tracker are free to use. The powerful features - categories, notes, analytics, reports and cloud sync - are Pro.
One subscription covers both tools. No ads. No data harvesting. Just tools that respect your time.
A tool, not a hook
Different from other focus apps
Most focus apps gamify deep work - trees, streaks, points. Quiet Control shows you your peak hours and helps you protect them. Once you know your window and you're defending it, the app's job is mostly done. Come back to recalibrate when your schedule changes - not because of a notification.
FAQ
Common questions
Deep work is the concept popularized by Cal Newport: cognitively demanding tasks performed in a state of distraction-free concentration. It's the work that produces real output - writing, coding, designing, analyzing. The opposite, "shallow work" (email, meetings, Slack), feels busy but doesn't move the needle.
Most knowledge workers think they do 6-8 hours of deep work. The real number, once they measure it, is usually 2-4. Cal Newport himself argues that around 4 hours of true deep work is near the upper limit for sustained daily output. Tracking is how you find out where you actually stand.
Deep work requires sustained focus and produces real value (writing code, solving hard problems). Shallow work is logistical and reactive (email, meetings, status updates). Tagging sessions by category here makes the split visible - and usually surprising.
Yes - that's its job. Over a few weeks of tracking, the heatmap reveals when you actually do your best focused work. For most people the pattern is clear: morning deep work hours hit hardest, late afternoon trails off. Scheduling your day around your peak window is one of the highest-leverage changes you can make.

The other half of Quiet Control
A free Habit Tracker to match your focus
Quiet Control is a system, not just a deep work timer. Alongside this timer you get a free Habit Tracker for the routines that keep deep work sustainable - sleep, exercise, breaks, a shutdown ritual. Together they show where your deep work hours actually go and whether they're compounding into the work you actually want to be doing. One account, one subscription, both tools.
