Features & Capabilities

BlockClock is a strict Pomodoro technique Chrome extension designed to boost your productivity by enforcing 25-minute distraction-free work sessions followed by 5-minute breaks. Unlike other timers, BlockClock does not allow cancellation once a session starts, ensuring you stay committed to your workflow. It helps enforce focus by blocking distracting websites during work intervals.

This extension is a fork of the formerly known Strict Workflow, updated for Firefox compatibility and rebranded as BlockClock. It remains open source and actively maintained, with future feature enhancements planned. Developers and users can access the source code on GitHub to explore or contribute.
