| description | Introduction: Disability associated with the symptoms of post-COVID-19 syndrome is one of its main features and can have a considerable impact on care and rehabilitation units. This, linked to a decreased aerobic capacity and endurance in post-COVID-19 syndrome patients, increases interest in studying the potential of mobile applications to assess performance capacity. The purpose of this research was to study how a free mobile application assesses aerobic capacity and endurance and its relationship with aerobic capacity, test-retest reliability, and endurance evaluated by a conventional test, along with fatigue and health-related quality of life. Methods: An observational study was conducted. RUNZI<sup>®</sup>, a free mobile application, was used by mounting a Samsung Galaxy S8 smartphone using a strap on the right forearm while all participants simultaneously performed a 6-Minute Walking Test (6MWT). Construct validity between the 6MWT and the total distance performed evaluated by RUNZI<sup>®</sup> was explored. Additionally, evaluation scales to assess fatigue (MFIS) and health-related quality of life (SF-36) were used to analyze the construct validity of RUNZI<sup>®</sup>. For test–retest reliability of the app, the same instructions about the 6MWT and procedure with the app were given to all participants at two different time periods. Results: A total of 16 post-COVID-19 syndrome patients (15 females and 1 male) completed the procedure. Distance measured with the RUNZI<sup>®</sup> showed an excellent correlation with the 6MWT assessed conventionally (<i>p</i> < 0.0001; r = 0.851). No statistical correlations were found between the distance assessed by the RUNZI<sup>®</sup> app with MFIS and the SF-36. Test–retest reliability was found to be close to statistical significance (<i>p</i> = 0.058) for distance (m) measured by RUNZI<sup>®</sup> with an ICC of 0.482. Conclusions: Instrumental 6MWT assessed by the RUNZI<sup>®</sup> app for the Android<sup>®</sup> operating system showed an excellent correlation with conventional 6MWT, indicating its construct validity in post-COVID-19 syndrome patients. Further, values for the test–retest reliability for the free mobile application were close to statistical significance with a reliability considered poor in an indoor setting. |
