Clinical-grade smartphone platform that measures reaction-time variability and motor–cognitive function at home, turning simple tasks into longitudinal, clinician-ready metrics.

I developed this app along side Dr. Brendan McNeish MD and validated for reliability against the gold-standard ReactStick in a study with over 40 participants. This app turns a smartphone into a clinical reaction-time tester, guiding users through brief tasks and capturing millisecond-level responses via onboard sensors. It computes intra-individual variability and related motor-cognitive metrics, then tracks how those measures change over time. Results are summarized as clear trends with exportable reports, giving clinicians and researchers an easy way to spot early changes and monitor progress.

It was a finalist in the 2024 Kuzneski Cup and won fourth place in the 2025 Big Idea Competition.
