IDUN Technologies is recruiting testers for its new Insights app and IDUN Guardian 4 brain-sensing earbuds. Using EEG from the earbuds, the app tracks three brain metrics around the clock: Engagement, Relaxation, and Brain-Battery® (showing when your brain is drained or recharged). It also offers trend views of how metrics shift across activities like meetings, breaks, and writing, plus a personal EEG baseline calibrated 1-2 minutes daily.
