A smart wearable cap that measures brain activity (EEG), heart metrics (PPG), and movement (IMU) and sends data to the companion app.

Consumers interested in focus, relaxation, and performance; students; researchers and developers; wellness enthusiasts.

No — it’s not intended to diagnose, treat, cure, or prevent any disease.

The hat, charging cable, and a quick-start guide. If anything is missing, contact support with your order number.

No — the hat uses dry sensors designed for comfortable wear.

We offer sizes Large, Medium, and Small.

Yes. Clean the contact points between users and create separate app profiles for each.

 Android, iOS, Windows, and macOS.

Bluetooth 4.2 (Classic & Low Energy).

Use the pair button in the app. If you previously paired in OS settings, “Forget” the device there, then pair it in the app.

No — connect to one device at a time. You can switch by disconnecting and pairing with the other.

Yes, for local sessions. Some features (cloud backup, updates) need the internet.

 Yes — it enables syncing, backups, and support.

 Add links to Google Play/App Store and your desktop app page.

You need the app for setup, pairing, updates, and viewing metrics.

Yes — export from the app (CSV/JSON). See Data & Privacy below.

Yes — export and share files, or invite them to view a shared report if you enable that feature.

Electrical activity at the scalp (8 channels). The app estimates states like focus/relaxation using algorithms.

Heart rate, HRV, oxygen saturation (SpO₂), and respiration rate derived from optical signals.

Motion/gestures with a 9-axis sensor.

Consumer-grade device optimized for at-home use. Accuracy depends on fit, placement, movement, and lighting (for PPG).

Hair can reduce contact. Part hair under the sensors and tighten the strap to improve contact quality.

Yes — the app shows live metrics and can provide on-screen prompts during sessions.

Yes — use tags/notes before or after a session.

Up to ~4.5 hours of continuous use under typical conditions.

About 2–3 hours with the supplied cable and a 5V adapter.

For safety and signal quality, we recommend using it on battery power only.

Yes — available via our Repair & Service program.

Try another USB adapter/cable, check the port for debris, charge at room temp, and confirm the charge indicator. If still failing, contact support.

Center the crown, adjust the strap snug (not tight), and ensure sensors touch skin.

Part hair where sensors touch (front/top), gently press and re-seat, then run the app’s Contact Quality test.

Wipe sensors with a soft, slightly damp cloth or alcohol wipe; avoid soaking electronics. Share your official cleaning steps.

Light activity is fine; heavy sweating or rain may degrade signals. Keep it dry.

Yes — ensure they don’t press sensors off your scalp.

Charge the hat → install the app → create account → power on → pair in the app → run Contact Quality → start a test session.

Keep battery >50%, keep the app in the foreground, stay within 1–2 m. If an update stalls, retry; use Recovery mode if prompted. Support can help.

The app shows live status: Bluetooth connected, firmware up-to-date, and contact quality Good.

Most users start with 5–20 minutes and adjust to their goal.

Yes — the app continues recording while audio plays.

Yes — use markers to note events you want to review later.

Yes — that’s the default. You can disable streams if needed in settings.

EEG, PPG, IMU signals; basic account info (e.g., email); and app usage needed for functionality.

No.

Not without your consent. Research data is shared only in anonymized form, if you opt-in.

Encrypted in transit and at rest. Personal info is stored separately from raw biosignals.

Yes — export in CSV/JSON from the app. You can request account/data deletion from the app or support.

We follow applicable privacy laws and provide access, export, and deletion controls.

Yes for local sessions; cloud sync is optional.

Charge >20% → “Forget” in OS Bluetooth → toggle Bluetooth off/on → pair inside the app → grant permissions. If still stuck, try a second phone and contact support.

Keep the phone within 1–2 m, disable aggressive battery savers, and avoid crowded 2.4 GHz environments.

Grant Location permission (Bluetooth requirement), disable battery optimization for the app, and leave the app in the foreground during updates.

Enable the app’s Bluetooth permission; keep the app in the foreground during updates.

Re-seat the hat, part hair under sensors, clean contacts, move away from power bricks, and rerun the test.

Check contact quality and session type, ensure the hat is connected, then restart the session.

Ensure skin contact at the optical sensor, reduce movement and bright ambient light, and retry.

Run Recalibrate in settings; keep the hat stable during calibration.

Battery >50%, phone near the hat, try again; if it repeats, follow Recovery mode steps in the app or contact support.
