The NextSense app includes a Demo page that lets you explore real-time brain signals and early, experimental experiences built on them.
The Demo page is designed for curious users who want to experiment, learn, or see what their brain is doing in the moment. It’s a window into features that are still in development, rather than a polished experience. You can find it in the NextSense app here: Settings → Labs → Demo
On the Demo page you can:
View real-time EEG signals from your Smartbuds
Explore brain-responsive experiences
Experiment with features that may shape future Smartbuds experiences
Important things to know before you start
The Demo page is intentionally experimental. That means:
Features may feel rough or unfinished
Visualizations may change over time
Interpretations of brain state are approximate, not definitive
Data shown here should not be treated as medical or diagnostic information
What you’ll see on the Demo page
Wave visualization and band graph
A flowing, abstract visualization of EEG band activity, coupled with a snapshot of relative activity across common EEG frequency bands, updated continuously.
Delta (δ): Deep, slow activity often associated with sleep
Theta (θ): Drowsiness, early sleep, or inward focus
Alpha (α): Calm, relaxed wakefulness
Beta (β): Alertness, thinking, mental effort
Gamma (γ): High-frequency activity linked to complex processing
Gem Report
These labels are experimental metaphors, not diagnoses. They’re intended to explore how we might describe brain states in more intuitive, meaningful ways.
Meditation Jar
A brain-responsive meditation experience where the jar fills with different colors as brain activity patterns become more prominent. As your brain activity shifts, the experience responds in real time.
Raw EEG signals (Left & Right)
Two live waveforms , representing electrical activity detected by Smartbuds on each side of your head. These signals show raw brain activity over time. Spikes and dips are normal and can be influenced by movement, muscle activity, blinking, or changes in attention.
