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.

Questions & Answers

As answered by people managing Time Sink 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.

    I love that my job is sitting on my ass drawing stuff but there are definitely times when it is still Work that I have to force myself to keep doing. Sometimes I sort of sit there watching art fall out of my stylus. Sometimes I am Sisyphus muttering and cursing as I push this fucking stone up this fucking mountain for the millionth time.

    For time tracking I lean on Time Sink. If you want something more manual then I feel like there are a zillion task-tracking timers out there but I couldn't point you to any one in particular. Wikipedia says Toggl has an OSX app so maybe you wanna look at that one first. Source: over 4 years ago
