## What is Arctop?

Arctop turns your Master & Dynamic MW75 Neuro headphones into a real-time brain-computer interface. Connect over Bluetooth, stream 12 channels of EEG at 500 Hz, and watch your brain activity flow on screen the moment you put your headphones on.

REAL-TIME EEG STREAMING
- Connect to MW75 Neuro headphones in seconds
- Automatic on-head detection
- Packet rate, signal quality, and session timer at a glance
- Background streaming keeps your session running while you use other apps

COGNITIVE WORKLOAD
- Calibrate your personal workload model
- Start a session and measure your cognitive data in real time while you work

SESSION HISTORY AND METRICS
- Every session is recorded and organized in your history
- Review duration, average cognitive workload, and workload distribution
- Go deep on any session with workload over time, time-in-zone, and between-marker breakdowns
- Download your own workload data as CSV files
- Weekly insights and streaks on your personal dashboard

PRIVATE BY DESIGN
- Sign in with your Google account
- Your neural data never leaves your device unencrypted
- Your brain data belongs to you — delete your account (and data) at any time

TRY IT WITHOUT HARDWARE

REQUIREMENTS
- Master & Dynamic MW75 Neuro headphones for live EEG streaming (Demo Mode works without them)
