A novel smartphone application is reliable for repeat administration and comparable to the Tekscan Strideway for spatiotemporal gait

•Data suggest that the Gait Analyzer and Tekscan Strideway are reliable over time and can comparably calculate velocity and cadence.•At time point one and time point two, the devices were moderately to strongly correlated to one another for both velocity and cadence.•The novel smartphone application may be used to collect reliable gait data for those in the future possibly in at-home locations.
