The Problem

People trying to control distracting websites and apps cannot rely on current blockers to enforce their rules consistently. Common failures include broken timers, incomplete blocking, weak uninstall protection, device-sync problems, excessive permissions, and global settings that interfere with legitimate sites. Easy deactivation defeats the buyer's core goal of creating dependable friction against impulsive use.

Potential Solution

Build a cross-device distraction firewall with per-site profiles, allow-only sessions, usage allowances, scheduled blocks, and deliberate exit challenges. Rules synchronize through encrypted configuration data while page contents, email, and browsing history remain inaccessible to the service. Enforcement begins with a browser extension and desktop companion, followed by supported mobile controls, with transparent diagnostics showing why a rule did or did not activate.

Why Now?

Recent reviews across multiple established blockers show that reliability, privacy, synchronization, and bypass resistance remain unresolved together. Growing use of multiple computers and phones makes device-specific configuration increasingly ineffective.

Block - App & Site Blocker

best blocker I've used, it actually has options to keep you from turning it off. one niche problem I have though, is that it won't block the YouTube website. I use Firefox browser, and watch YouTube on that, as it allows ad blocking extensions on mobile, but this app doesn't seem to be able to detect when the YouTube website is open. please fix!
