The short version
Brain.fm is functional music engineered to support sustained attention. NGUMU: Screen Time Control is a browser extension that combines work-break timers, intelligent website blocking, enforced full-screen breaks and local productivity analytics in a single popup.
They overlap less than the category labels suggest. Brain.fm is a focus audio service; NGUMU is an enforcement layer for the browser where most knowledge work — and most procrastination — actually happens.

Where Brain.fm is genuinely good
- Audio that masks an open-plan office better than most playlists
- Session lengths that nudge you into a defined block
- Backed by published research on attention and audio
We're not interested in strawmen. If the list above describes your bottleneck, Brain.fm is a good purchase and you should make it.
Where Brain.fm leaves a gap
- It changes your environment, not your browser
- No blocking, no break enforcement, no focus analytics
- Subscription on top of whatever else you use
The pattern behind all of these: a tool that lives outside the browser can advise, measure or motivate, but it cannot close the tab. The moment attention wobbles, the distracting site is one keystroke away.
Where NGUMU is stronger
1. Blocking that only runs when you're working
NGUMU enforces blocklists while a focus session is active and steps out of the way the rest of the day. Curated presets cover social media, video streaming and news, so setup is seconds rather than an afternoon of regex.
2. A rhythm, not just a restriction
Blocking removes the bad option; it doesn't create the good one. Pomodoro (25/5), 52-17, 90-20, 20-20-20 or a custom cycle give the session a shape and a finish line. See the full feature list for every cycle.
3. Breaks you actually take
A full-screen overlay makes returning early deliberately awkward, and a pre-break "blink warning" prompts you to rest your eyes before the screen changes — the part almost every competitor skips.
4. Honest numbers, kept local
Focus minutes, session counts, goal progress and streaks live in the NGUMU dashboard and stay in your browser's local storage. No account, no upload, no personal data collected. You can export everything to JSON or CSV whenever you like.
5. Try it before choosing a paid plan
First-time users get a 40-day free trial. NGUMU has no free plan; continued use afterwards requires a paid plan. See pricing and the extension’s purchase screen for current pricing and billing terms.
Choose Brain.fm if…
- Noise is your main distraction and headphones are your fix
Choose NGUMU if…
- Your distraction arrives through tabs, not through your ears
Can you use both?
Yes, and plenty of people should. Brain.fm in the headphones, NGUMU in the browser — they solve different halves of the same problem.
