Body flexibility is crucial for physical performance, injury prevention and health maintenance. With the rise of mobile applications, it is necessary to review the quality of their content and determine if they really do what they offer. The purpose of the study was to evaluate the objective, subjective quality as well as the perceived impact of a group of mobile applications used in the development of body flexibility. The Delphi research was adopted, allowing evaluation of five mobile applications through the consensus by a panel of experts. This panel included physiotherapists, fitness professionals, flexibility specialists and sports professionals. The instrument used was the user version of the Mobile Application Rating Scale (uMARS). The results showed that the “Exercises for children at home” app excelled in terms of objective quality, highlighting its interactivity and intuitive graphics. The “Stretching” application was the best rated in subjective quality, offering customizable options and configurable reminders that were highly appreciated by users. Meanwhile, “Stretching exercises, flexibility training” stood out for its perceived impact, providing structured training plans that significantly improved the flexibility and postural health of users. In conclusion, it is necessary to carry out thorough reviews of the impact and quality of mobile applications developed in the field of sports and other areas of knowledge, emphasizing the importance of these technological resources in promoting the health and well-being of people.
