IDUN Insights is a new mobile app from IDUN Technologies that pairs with the Guardian 4 in-ear EEG earbuds. The Insights app allows users to measure their brain metrics: Engagement, Relaxation and Brain-Battery throughout the day and night.
The IDUN Guardian earbuds record electrical brain activity (EEG) from inside the ear and processing this data to create the brain metrics.
This launch program explores how people experience the device and app in everyday life: how clear the setup and features are, how comfortable and useful the experience feels, and whether people would want to continue using it.
You do not need a background in EEG or neuroscience to participate.

IDUN Insights Mobile App
Get to know your brain throughout the day.

Start a Focus or Relaxation session and explore how your insights change while you work, read, or unwind. Check-in with how you feel and log your activities to connect your brain activity with everyday experiences. Your Insights Trend helps you explore trends over time, while regular wear builds a personal baseline that makes your insights more tailored to you.
The Insights app includes Brain Agent, your in-app AI assistant. Ask questions about your recorded insights, compare sessions, and explore patterns across your recent activities. It brings your brain data and personal context into a conversation, helping you reflect on your routines and discover what works for you.
