To evaluate the usefulness of a novel acoustic uroflowmetry\u2010 (UFM\u2010) based mobile application (app) voiding diary (VD) focusing on the (1) compliance and (2) correlation with a conventional paper\u2010based VD. <jats:italic>Materials and Methods<\/jats:italic>. A total of 78 patients were included between December 2019 and June 2020, and a subsequent review of all data was performed. The analyzed data were as follows: (1) survey of convenience\/satisfaction\/preference comparing the two methods, (2) compliance regarding the completeness of both methods, and (3) correlation of each metric (24\u2010hour urine volume, nocturnal urine volume, nocturnal polyuria index, total number of voids, number of daytime voids, number of nocturnal voids, and maximal bladder capacity) between the two methods. <jats:italic>Results<\/jats:italic>. The survey results of convenience, satisfaction, and preference were as follows. With regard to convenience and satisfaction area, higher scores are reported in the mobile app VD (mean \u00b1 standard\u2009deviation (SD); convenience: 7.47 \u00b1 2.19 [app] vs. 4.20 \u00b1 2.49 [paper]; satisfaction: 7.36 \u00b1 2.17 [app] vs. 5.07 \u00b1 2.65 [paper]). The median score of the overall preference for using the mobile app instead of the paper\u2010based VD was 9 out of 10 (mean \u00b1 SD7.82 \u00b1 2.68). We also found a good correlation between the two methods for nocturnal urine volume (<jats:italic>r<\/jats:italic> = 0.55, <jats:italic>p<\/jats:italic> = 0.04), nocturnal polyuria index (<jats:italic>r<\/jats:italic> = 0.66, <jats:italic>p<\/jats:italic> = 0.23), total number of voids (<jats:italic>r<\/jats:italic> = 0.9, <jats:italic>p<\/jats:italic> = 0.02), number of nocturnal voids (<jats:italic>r<\/jats:italic> = 0.83, <jats:italic>p<\/jats:italic> = 0.02), and maximal bladder capacity (<jats:italic>r<\/jats:italic> = 0.89, <jats:italic>p<\/jats:italic> = 0.04). <jats:italic>Conclusion<\/jats:italic>.
