I Built a Focus App Because Every Distraction Blocker Failed Me

I've tried every focus app on macOS. Freedom, Cold Turkey, SelfControl, Focus, One Sec — all of them. None of them stuck. Here's why, and what I built instead.

The Problem With Existing Focus Apps

Every distraction blocker I tried had the same fundamental flaw: they treat focus as a binary state. You're either "blocked" or you're not. But real focus doesn't work that way.

Here's what actually happens during deep work:

  1. You start working
  2. Your brain gets an urge to check something (Twitter, email, Slack)
  3. If the app blocks it, you feel frustrated and find a workaround
  4. If the app lets you through with a "are you sure?" prompt, you click yes every time
  5. Either way, the focus is broken

The issue isn't blocking. It's awareness.

What I Built

Monk Mode takes a different approach. Instead of just blocking, it tracks every time your brain tries to distract you during a focus session. Every URL you try to visit, every app you try to open — it logs the impulse.

At the end of a session, you get a distraction report:

  • 14 times you tried to open Twitter
  • 7 times you tried to check email
  • 3 times you tried to open YouTube

Seeing the raw numbers is more powerful than any block. It creates self-awareness about your distraction patterns that no blocker can provide.

The Stack

  • SwiftUI for the UI
  • macOS Accessibility APIs for app monitoring
  • Network Extension for URL tracking
  • Local-first — no data leaves your machine

Key Design Decisions

Blocking + awareness, not just blocking. The app does block distractions, but the awareness layer is what actually changes behavior over time.

Session-based, not always-on. You start a session when you want to focus. No persistent background monitoring.

No subscription. $15 lifetime, or $10 with code DEV. I hate subscription fatigue for utility apps.

Results

After using it myself for 3 months:

  • Average focus session went from 25 min to 52 min
  • Distraction attempts dropped from ~40/session to ~12/session
  • The awareness effect compounds — you start catching yourself BEFORE reaching for the distraction

What I Learned Building It

  1. macOS security APIs are painful. Network Extensions require special entitlements and Apple review. Took 3 weeks just to get approval.
  2. Users want data, not just restrictions. The distraction report is the #1 feature people mention in reviews.
  3. Simplicity wins. Every feature I removed made the app better.
