Cold Turkey Blocker — desktop blocker impossible to bypass. One-time purchase, no subscription.

The “nuclear option” of blockers: once locked, you can’t turn it off. For an ADHD brain that knows its relapse patterns, it’s a precious commitment device.

The $39 for life is a refreshing anti-dark-pattern in a market saturated with subscriptions.

Caveat: extreme rigidity can be a problem if you genuinely have an urgent need. Use it for recurring planned focus blocks.
