Focus 45 is a time-management and anti-distraction productivity extension for the Google Chrome browser designed to enforce dedicated periods of deep work. It adapts the traditional Pomodoro technique by lengthening the core concentration window to better suit tasks requiring sustained, complex thinking. Core Mechanics & Features
45-Minute Work Intervals: The extension defaults to a rigid 45-minute countdown timer meant entirely for high-concentration tasks.
3-Minute Rest Periods: Once the work sprint finishes, it transitions into a brief 3-minute break to help you mentally reset without losing momentum.
Customizable Website Blacklists: Users curate a personal list of time-wasting websites (such as social media or news feeds).
Hard Content Blocking: During an active 45-minute session, access to any URL or platform placed on your blacklist is strictly blocked.
Cheeky Visual Interface: Compared to more sterile productivity tools, Focus 45 uses a colorful and slightly humorous user interface to keep tracking your time engaging. How It Compares to Traditional Pomodoro
Most standard focus tools default to the classic 25-minute work and 5-minute break structure. While 25 minutes works well for administrative tasks or overcoming initial procrastination, complex workflows—like coding, writing, or deep research—often require longer blocks of time to enter a true “flow state”. Focus 45 shifts the ratio specifically to favor these prolonged stretches of uninterrupted thinking. Getting Started
To use it, look up the extension directly on the Chrome Web Store (or native browser extension management settings). Once added, click the icon in your toolbar, input your primary distracting websites into the restriction list, and launch the timer to lock down your browser session. If you are looking to optimize your workflow, let me know:
What specific types of tasks you are trying to focus on (e.g., writing, studying, development)?
If you prefer strict website blocking or just soft reminders to stay on task?
