Frequently asked questions
Everything you need to know about Flocus and flow state tracking.
Getting Started
What is Flocus?
Flocus is a focus app with a real daily planner built in. Each morning you pick your most-important task and a short list, run pomodoro focus blocks against the plan, and close your Focus Ring when the day is done. Optionally, it pairs with Muse EEG headbands to track your flow state in real time while you work — depth no other planner has.
Is this the same as other apps called Flocus?
No — 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 focus app with a real plan — a daily planner, focus blocks, and a ring to close — and the only one that can read your brain via Muse EEG. For an honest rundown of who's who, see flocus.org/which-flocus.
What hardware do I need?
None required — the daily planner and focus timer work completely hardware-free. If you want real-time flow tracking, Flocus works with all Muse headbands, including the original Muse, Muse 2, and Muse S (Gen 1 and Gen 2). These are consumer-grade EEG devices that connect via Bluetooth. You can purchase them from the Muse website or Amazon.
What browsers are supported?
Flocus requires Web Bluetooth, which is supported in Chrome, Edge, and Opera on desktop. Safari and Firefox do not support Web Bluetooth. For the best experience, we recommend using the Flocus desktop app for Mac or Windows.
Does Flocus work on mobile?
The daily planner works on your phone — plan your day, run focus blocks, and close your Focus Ring from any mobile browser (add Flocus to your home screen for an app-like experience). Muse headband sessions need a desktop browser with Web Bluetooth, since mobile browsers can't connect to the headband.
Flow Tracking
How does Flocus detect flow states?
Flocus analyzes your brainwave patterns using the theta/beta ratio, which is scientifically associated with focused attention and flow states. We combine this with fatigue detection and trend analysis to give you a real-time flow score from 0-100.
What do the different states mean?
Flow (green) means you're in an optimal state of focused attention. Overload (red) indicates cognitive strain—you may need a break. Low Engagement (blue) suggests you're not fully engaged with your task. Your goal is to maximize time in flow.
How long does calibration take?
Calibration takes about 30 seconds. During this time, sit still and relax while Flocus establishes your baseline brain activity. This baseline is used to personalize your flow detection throughout the session.
Why is my flow score different each session?
Your brain state varies based on sleep, stress, caffeine, time of day, and many other factors. Flocus calibrates at the start of each session to account for these variations, so your flow score reflects your current cognitive state.
Pomodoro Mode
What is Pomodoro mode?
Pomodoro mode structures your work into timed intervals (default 25 minutes) followed by short breaks. Flocus adapts the traditional Pomodoro technique with EEG data—extending work intervals when you're in flow and suggesting earlier breaks when you're fatigued.
Can I customize the work/break durations?
Yes! Before starting a session, click the settings icon next to the Pomodoro toggle to customize work duration (15-60 min), short break duration (3-15 min), and long break duration (10-30 min).
What are Flow Extensions?
When you're in deep flow at the end of a work interval, Flocus can automatically extend your session rather than interrupting you. This is one of the key benefits of EEG-enhanced Pomodoro tracking.
Subscription & Pricing
Can I try before I buy?
Absolutely! The free tier is free forever: plan your day (your most important task plus up to 3 tasks), set up to 5 weekly goals, run up to 6 focus blocks a day, and close your daily Focus Ring — plus one 30-minute headband session per day. No credit card required. Pro adds a 14-day free trial on top.
What do I get with Pro?
Pro removes every cap: unlimited tasks, goals and focus blocks, planning ahead for any future day, insights, weekly & monthly recaps, focus reminders, full history with cloud sync, and unlimited Muse neurofeedback sessions. $99/year or $12.99/month, both with a 14-day free trial.
Can I cancel my subscription anytime?
Yes, you can cancel at any time from your account settings. Your Pro access will continue until the end of your billing period, then you'll return to the free tier.
Do you offer team or enterprise plans?
Not yet, but we're working on it. Contact us at josh@flocus.org if you're interested in using Flocus for your team.
Technical
Is my brain data private?
Yes. Your EEG data is processed locally in your browser and is never sent to our servers. Only aggregated session metrics (flow score, duration, etc.) are stored if you create an account, and you can delete your data at any time.
Why won't my Muse connect?
Make sure Bluetooth is enabled on your computer, your Muse is charged and turned on, and you're using a supported browser (Chrome, Edge, or Opera). If you're still having trouble, try restarting your Muse by holding the power button for 10 seconds.
What's the difference between Classic and Athena protocol?
These are two different Bluetooth protocols used by Muse devices. Most Muse 2 and Muse S devices use the Classic protocol. Some newer Muse S (Gen 2) devices use Athena. Flocus auto-detects the correct protocol, but you can override it in Advanced Settings if needed.
Can I export my session data?
Currently, you can view all your session data in the app. Full data export functionality is on our roadmap.
