## Description

<strong>Tired of website blockers that just don't work?</strong>

Most fail for one of two reasons. They're too strict, so you end up disabling them permanently. Or they're too lenient, so you quickly find a way around them.

DecayBlock offers a smarter solution: adaptive friction. It adds a small timeout before you can access a distracting site. This timeout grows the more you visit these sites, and decays when you stay away.

<strong>How it works:</strong>
<ul><li>Add websites to your Dashboard and choose how to regulate them: either apply a timeout or block them entirely. You can also categorize sites, like social media or news, or permanently block content such as adult sites.</li><li>When you visit a regulated site, a timeout is applied before you gain access. This timeout increases with continued browsing, gently nudging you to adjust your habits.</li><li>When you stop visiting regulated websites, your accumulated timeout gradually decreases.</li><li>You can easily customize the timeout growth rate (how quickly the timeout builds) and the decay half-life (how fast it reduces) to tailor the extension to your personal productivity goals. You can also set a minimum timeout (e.g., 5 seconds minimum at all times).</li><li>You can also view a chart of your timeout history to see your progress.</li></ul>
