FocusStack

Most productivity tools tell you where your time went after you get distracted.

FocusStack helps you stay focused while the work is happening.

Start a focus session, name the task youโ€™re working on, and pick a project. FocusStack automatically tracks the apps and websites you use, blocks distractions youโ€™ve chosen to avoid, and nudges you when your attention starts drifting.

At the end of the day, you get a complete picture of where your focus actually went, how much time each project received, and whether your actions matched your intentions.

  • Automatic app and website tracking
  • Distraction blocking

  • Lifetime access

Built for

  • Founders
  • Developers

Possible disadvantages of LeechBlock

  • Limited Browser Support
    LeechBlock is primarily available as a browser extension and its functionality can be limited depending on the browser used. It may not support all browsers or may have inconsistent performance across different browsers.
  • Dependency on Browser
    As a browser extension, LeechBlock only works within the browser in which it is installed. It does not block apps or other browsers, reducing its effectiveness if users switch browsers or use different devices.
  • Potential for Workarounds
    Users determined to bypass the restrictions may find ways to disable or circumvent LeechBlock, which can undermine its effectiveness in controlling browsing habits.
  • Lack of Advanced Features
    Compared to some paid or more comprehensive web-blocking software, LeechBlock may lack advanced features such as detailed usage reports, cross-device synchronization, or parental controls.
  • Learning Curve for Detailed Configuration
    While basic use is straightforward, configuring more complex rules and settings might require a bit of a learning curve, especially for users who want to take full advantage of its customizability.

Questions & Answers

As answered by people managing LeechBlock and FocusStack.

What makes your product unique?

FocusStack's answer:

Most productivity tools are passive. They tell you where your time went after the day is over.

FocusStack is designed to help while the work is happening.

  • Focus sessions keep you locked on a specific task
  • Distraction blocking prevents attention leaks
  • Smart nudges help you catch yourself when you drift
  • Automatic tracking shows where your focus actually went
  • Workspace Stacks launch your entire work setup with one click

FocusStack combines focus, time tracking, and productivity insights into a single workflow.

How would you describe the primary audience of your product?

FocusStack's answer:

FocusStack is built for people who spend most of their day on a computer creating, building, studying, or solving problems.

Typical users include:

  • Founders
  • Developers
  • Freelancers
  • Designers
  • Students
  • Researchers
  • Remote workers
  • Knowledge workers

Anyone who wants to reduce distractions and spend more time doing meaningful work can benefit from FocusStack.

Why should a person choose your product over its competitors?

FocusStack's answer:

Most competitors focus on measuring productivity.

FocusStack focuses on improving it.

Tools like Toggl, Clockify, and many time trackers are great at recording hours. FocusStack goes a step further by helping users stay attentive while theyโ€™re working through focus sessions, distraction blocking, and real-time nudges.

Users donโ€™t just learn where their time went. They actively protect where it goes next.

What's the story behind your product?

FocusStack's answer:

FocusStack started with a simple frustration.

I would sit at my computer for hours, feel busy all day, and still wonder where my time had gone.

I tried existing productivity and time-tracking tools. They were useful for understanding what happened after the fact, but they didnโ€™t help me stay focused in the moment.

So I started building a tool for myself.

The idea was simple: create something that could help me stay attentive while working, automatically track my activity, block distractions, and show me how I actually spent my day.

What started as a personal tool quickly became FocusStack.
