TL;DR
A handful of apps and browser extensions promise to cut down time-wasting habits by blocking sites, apps or even whole devices. Options range from lightweight, free extensions to paid cross-device tools and rigid lockdown modes for strict accountability.
What happened
As people look to improve productivity, several distraction-blocking tools are highlighted for different needs. Freedom can block chosen sites and apps across multiple devices, schedule recurring sessions, disable the internet entirely, and enforce sessions with a "Locked Mode"; it starts at $3.33 per month billed annually, with other billing options and a seven-day trial. Cold Turkey emphasizes strict locking: once a block starts it is effectively non‑cancelable, and a "Frozen Turkey" mode can lock a computer; basic features are free and a one-time $39 fee unlocks scheduling and app blocking. Opal provides focus blocks and category-based limits for iPhone, Android and desktop, with usage stats and a focus score; basic use is free, with premium tiers. LeechBlock NG is a free browser extension that blocks or delays page loads. Forest gamifies focus by growing virtual trees and donates to real planting projects; it offers a free browser extension and paid mobile apps.
Why it matters
- Different approaches match different self-control styles — from soft nudges to irreversible lockdowns.
- Cross-device blocking can stop distractions when users switch between phones, tablets and laptops.
- Built-in scheduling and recurring sessions help make focus periods habitual rather than ad hoc.
- Tracking features and gamification provide feedback that can reinforce sustained behavior change.
Key facts

- Freedom pricing starts at $3.33 per month when billed annually, $8.99 per month billed monthly, and includes a $199 lifetime option plus a seven-day free trial.
- Cold Turkey makes it difficult to stop an active block, includes a "Frozen Turkey" computer lock mode, and offers basic features for free; a one-time $39 fee unlocks scheduling and app blocking.
