Key insights: The opportunity for cognitive tracking

Of the 128 million U.S. adults aged 35–65, an estimated 45% use health trackers. Assuming 70% are interested in long-term preventive monitoring and 46% of that group are interested in cognitive tracking, this suggests an initial potential audience of approximately 19 million people.

• Health tracking is part of everyday life. Smartwatches and health trackers have made personal health data familiar to millions of Americans. Cognitive tracking offers a natural next step for people who already want to understand their health better. (Pew Research Center, 2026; Nagappan, Knowles, & Krasniansky, 2024)
• Today’s insights. A longer-term perspective. Interest in healthy aging and ongoing health tracking creates an opportunity to bring cognitive wellness into everyday routines. CogniTracer’s vision is to help people get to know their cognitive patterns over time. (Callaghan et al., 2024; Steinhart, Hupfer, & Upadhyaya, 2022)
• Brain health deserves a place in the picture. Public interest in brain health and research into smartphone-based cognitive monitoring point to an opportunity for more accessible ways to understand cognitive wellness. The epilepsy study offers an encouraging perspective from a specific patient population; interest across the broader public may differ. (Alzheimer’s Association, 2026; Helmstaedter, Von Wrede, & Al-Haj Mustafa, 2025)
• More dimensions. A clearer picture of cognitive health. Combining signals from language, speech, and everyday interactions could help reveal subtle cognitive changes and support monitoring over time. Research shows that combining facial and voice signals can outperform either alone in detecting cognitive impairment—an encouraging foundation for a more complete view of brain health. CogniTracer’s vision is to turn that broader perspective into awareness that helps people take proactive steps toward protecting their cognitive health. Monitoring itself has not been shown to prevent cognitive decline. (Shankar et al., 2025; Takeshige-Amano et al., 2024)
• Make brain health part of the longevity journey. Digital health is moving toward personal baselines and ongoing care, creating an opportunity to make cognitive tracking part of everyday healthy aging. BrainHQ highlights the market for brain training, while the NIH-funded ACTIVE trial found a 25% lower rate of dementia diagnosis over 20 years among older adults receiving specific speed training with booster sessions—a training result, not a monitoring benefit. CogniTracer’s vision is to build on this momentum with accessible, continuous tracking that turns everyday signals into a clearer understanding of cognitive health over time.
