Bland-Altman plots for validity.
(A) Comparison of the app-based and distance wheel measure of the 6MWT distance. (B) Comparison of the app-based and observed performance at the 30s-STS test. The upper and lower lines represent the 95% limits of agreement, and the center line indicates the mean difference.

Linear regressions plots for validity.
(A) Comparison of the app-based and distance wheel measure of the 6MWT distance. (B) Comparison of the app-based and observed performance at the 30s-STS test. The dotted green line at 45 degrees represents equality between the results.
