Challenge your brain and track your progress with real-time, visual results. The Thinkie app offers a broad range of games specifically designed to engage you and help keep your brain active and alert. You can track your progress with our “Brain Meter” that provides immediate input through an easy-to-use system displaying colors to show level of brain activity. Thinkie is built with fNIRS (Functional Near-Infrared Spectroscopy), which measures your brain activity through our special headband. Our design is guided by nearly 3 decades of research and development, all packaged into a brain training regimen that will help you stay cognitively sharp.
