"Focus app" covers tools that work in completely different ways. A pomodoro timer manages your time. An app blocker manages your environment. Flocus measures your attention itself — using a Muse EEG headband to show a live flow score. None of them is a replacement for the others; they target different links in the chain between sitting down and actually concentrating.
Side-by-side comparison
| Flocus | Pomodoro / study timers | App blockers | |
|---|---|---|---|
| How it helps you focus | Measures your brain's focus via EEG and shows a live flow score | Structures work into timed intervals and sets a focused mood | Removes distractions by blocking apps and sites |
| Measures your actual focus? | Yes — read from your brainwaves | No — it tracks time, not attention | No — it limits what you can open |
| Requires hardware | Yes — a Muse headband | No | No |
| Real-time feedback | Yes — a live flow score (0–100) | No — just a countdown | No |

What each tool is actually good at
Pomodoro and study timers are about structure and momentum. Breaking work into fixed intervals (classically 25 minutes on, 5 off) lowers the activation energy to start, creates a sense of urgency, and builds a repeatable routine. The aesthetic ones add ambient sound and a calming visual space to get you in the mood. What they can't do is tell you whether the time you spent was actually focused — a 25-minute timer counts down identically whether you were deep in thought or quietly daydreaming.
App and website blockers are about environment and willpower. By making it hard or impossible to open the things that pull you away, they remove the moment-to-moment decision to resist — which is genuinely effective when your main problem is distraction. But a blocker only governs what you can open; it has no idea whether the document you're allowed to work in actually has your attention. You can stare at an unblocked page completely checked out.
Flocus is about measurement. Using a Muse EEG headband, it reads your brain's activity and shows a live flow score, so you can see — not guess — whether you're focused, when you reach flow, and when fatigue is setting in. That feedback is the thing the other two categories structurally cannot provide, and it's why Flocus is the only one that needs hardware.
They're complementary, not competing
Because each tool targets a different problem, the best focus setup often combines them. An app blocker removes the temptation to wander; a pomodoro rhythm gives your session structure; and Flocus tells you whether any of it is actually working — whether you're truly in flow or just sitting still with a blocker on. The timer and blocker are about willpower and environment; the flow score is about measurement.
What makes a flow-state tracker different is that it's the only one of the three that reads your brain rather than your behavior. A countdown doesn't know if your mind wandered; a blocker doesn't know if the app you are allowed to use has your full attention. Flocus measures focus at the source, which is also why it's the one that requires hardware — a Muse headband — while the others run on software alone.
There's also a difference in what each tool leaves you with afterward. A timer leaves you with a count of intervals; a blocker leaves you with a list of things it stopped. A flow tracker leaves you with a record of how your focus actually behaved — when you hit flow, how long you held it, when fatigue crept in — which is the raw material for getting better over time rather than just getting through today. If you already lean on a timer or blocker and they're working for the jobs they do, the question isn't whether to replace them; it's whether you also want to see, and improve, the focus itself.
If you're deciding where to start: reach for an app blocker if your main problem is distraction, a pomodoro timer if it's getting started and pacing, and Flocus if you want to actually see and improve your focus. Many people end up using a timer or blocker alongside Flocus. Worth knowing: Flocus now includes a full daily planner with pomodoro focus blocks built in — see the daily planner with built-in focus timer. For the full how-to, see the Muse flow-tracking guide, or the features for what Flocus includes.
Which should you pick?
The fastest way to choose is to name the problem you're actually having:
- "I keep getting pulled into other apps and sites." Start with an app blocker — it directly removes the temptation.
- "I struggle to start, or to pace myself." A pomodoro or study timer gives you the structure and the nudge to begin.
- "I sit down to focus but I'm not sure I actually do." That's the gap a flow-state tracker fills — it measures whether the focus is real and helps you improve it over time.
For most people the honest answer is "more than one," because these problems coexist. The important thing is that adding Flocus doesn't mean giving up your timer or blocker — it sits on top of them and tells you whether the whole setup is working. If your goal is specifically to build a focus practice — to get measurably better at deep work rather than just getting through a session — the measurement layer is the piece the other two can't provide. The guide to using a Muse headband for deep work walks through that in detail.
Other apps also named "Flocus"
Worth clearing up, because it causes real confusion: a few different apps share the name "Flocus." There's an app blocker and an aesthetic study/pomodoro timer, among others. This Flocus — at flocus.org — is the flow-state tracker that connects to Muse EEG headbands to measure your focus in real time. If you arrived looking for one of the others, that's a different product with the same name; if you were looking for the EEG-based focus tracker, you're in the right place.
Try the flow-state tracker
If you have a Muse headband, you can try Flocus free — one 30-minute session a day, no credit card — and see what a real focus signal adds on top of whatever timer or blocker you already use.
