🚀 New Launches
Goyal announced Temple, a forehead sensor tracking cerebral blood flow and cognitive load when it ships late 2026. Nothing’s buyable yet, and brain monitoring has stayed niche for every consumer EEG device that’s tried it, so this is a watch item rather than a reason to hold off on a proven tracker.
Marty’s Take:
Cognitive load monitoring is the next frontier fitness brands are chasing, but Deepinder Goyal is entering a category dominated by companies with a decade of biosensor R&D, not a food-delivery balance sheet. A late 2026 timeline gives Whoop and Oura a full year to ship their own brain metrics first. Until Temple ships, the safer buy stays a proven tracker: check our best fitness tracker picks.
