Nowadays, smartphones are increasingly gaining space in the medical environment, the scientific evaluation of the real efficacy and reproducibility of this new technology is essential. In this context, our goal was to evaluate, unprecedently in our country, the smartphone linked sphygmomanometer (Withings Blood Pressure Monitor) with other methods (mercury, aneroid and digital sphygmomanometers). 45 healthy medical students were randomly selected from UFPR (Universidade Federal do Paraná), and three measures by each modality were taken and compared between them, in random order and on each person. The preference for self-measurement method between digital and smartphone linked sphygmomanometers was also evaluated. The obtained data were analyzed through paired t-Student and oneway Anova models, with significance of p<0,05. We obtained 576 measures; in the individual comparison of them, in relation to the systolic blood pressure (SBP), when equipments were confronted between each other, the smartphone didn’t present significant difference with the other methods (p>0,05), be in each measure by student or between methods. Regarding diastolic blood pressure (DBP), there was significant difference between smartphone’s measurements in relation to all other equipments (p<0,05). In the specific analysis of the repeated means in each student by each method, the smartphone was the only one to significantly differ of the other techniques, existing variability among each measure. Concerning the preference analysis, the matters of measurement time, discomfort of the compressive cuff and visual presentation didn’t significantly influence the final choice, in which 51,9% chose the smartphone and 29,6% the digital.
