NeuroMetrics: Focus & Flow

NeuroMetrics

About this app

NeuroMetrics turns a Muse EEG headband into a personal focus and flow coach.

See your focus, calm, engagement and a single, easy-to-read Flow Score update live as you work — then start a Focus session, pocket your phone, and get a clear report of how your session went.

WHAT YOU GET
• Flow Score — one calm 0-100 number that blends several well-studied brain signals, personalised to your own baseline.
• Mood reading — a sticky 0-100 mood estimate (calm, energised, tense or low) from the valence/arousal model, updated gently every ~30 seconds.
• Heart rate, heart-rate variability and experimental prefrontal oxygenation on supported Muse S Athena headbands.
• Focus sessions — start, lock your phone, and get a flow report with your time in flow, peaks, and tailored tips to improve your focus.
• Gentle coaching — opt-in tips when you drift, drowse, or tense up.
• A "?" on every metric that explains exactly how it's calculated, with links to the research.
• Optional account to sync your history and compare today against your own average. Or use it fully on-device, or sign in anonymously.

SUPPORTED HEADBANDS
• Muse 2 and Muse S (Athena) — full metrics including heart rate.
• Muse 1 — EEG metrics.
(Support for more headbands is in progress.)

YOUR DATA, YOUR CHOICE
• The app works fully on your device — an account is optional.
• Only summarised metrics sync when you sign in; your raw EEG stays on your phone unless you turn on the optional "Back up raw EEG recordings" setting.
• Delete your account and all data any time, in one tap.
• No ads. No third-party trackers.

IMPORTANT
NeuroMetrics is a wellness and self-insight tool. Its scores are personalised wellness estimates, not medical or diagnostic measures. It is not a medical device and does not diagnose, treat, or prevent any condition. A Muse headband (sold separately) is required.
