1. LockIn MCP — best for AI productivity
LockIn MCP is the only distraction blocker built as an MCP server. Your AI assistant can call get_agent_guidelines for coaching behavior, then block_domains, enter_focus_mode, temporarily_unblock_domains, and check get_block_status — all through natural language. System-level hosts blocking works across browsers on macOS, Linux, and Windows. One-line install, Pro from $2.99/month license.
- Pros: AI-native, cheap lifetime license, system-level desktop blocking, works with any MCP client.
- Cons: No dedicated mobile app (pair with Screen Time or Freedom on phone).
2. Freedom — best for all-device sync
Freedom blocks websites and apps across Mac, Windows, iOS, Android, and Chrome. Start a session on your laptop and your phone blocks too. ~$40/year; enable Locked Mode for stronger enforcement.
3. Cold Turkey — best for unbypassable desktop
When you need sites to stay blocked even if willpower fails, Cold Turkey is the gold standard. $39 one-time, Windows and Mac only, no mobile.
4. Opal — best iPhone focus app
Opal uses Apple's Screen Time API for genuine app blocking during sessions. Premium pricing (~$100/year) but excellent for phone-heavy distractors.
5–7. Honorable mentions
- One Sec — adds a breathing pause before opening distracting apps.
- ScreenZen — similar friction-based approach for Android/iOS.
- Forest — gamified focus timer; blocks by motivation, not system enforcement.
How to choose
- Identify where you get distracted — phone, desktop browser, or both.
- Decide if AI should manage blocking (→ LockIn MCP) or you prefer a manual app.
- Check budget: one-time (LockIn, Cold Turkey) vs annual (Freedom, Opal).
- Test enforcement: hosts blocking and Frozen Turkey beat browser-only extensions.
Our recommendation
For developers and knowledge workers in the AI productivity era, LockIn MCP plus free iOS Screen Time covers desktop and mobile for under $10 total. For phone-first users who want premium coaching, Opal wins. For strict all-device sync, Freedom remains the incumbent.
