Gait Analyzer utilizes smartphone-based sensors in order to compute gait parameters in real-time. Parameters currently include gait velocity, step time, step length, cadence, and symmetry (more coming soon, as we continue validating!). * Single- and dual-task cognitive and gait options available. Cognitive tests include an auditory Stroop task, n-back task, and verbal fluency task. Outcome parameters include reaction time and accuracy. * Save your raw and computed gait or cognitive data to a comma-delimited txt file in iCloud. * Just provide your body height and get started! Other optional demographic information can be provided, and will allow you to compare your walking characteristics to other gender- age- location- matched individuals. * Analyze your historical gait and cognitive data. * The methodology has previously been used to assess dual-task smartphone usage and has been shown to be valid and reliable: https://www.ncbi.nlm.nih.gov/pubmed/28961548 https://www.ncbi.nlm.nih.gov/pubmed/30445278
