There were 142 (26.3%) men and 397 (73.7%) women. The mean age was 33.3 ± 11.5. Health care workers and teachers found the application significantly more beneficial to promote cancer screening (p = 0.002). Ages and professions of the participants significantly associated with their opinions regarding the application completed their knowledge gaps and considering continue to use the application (p <0.0001, p = 0.02), (p = 0.04, p = 0.01). Prospects for recommending the application differed significantly with age, body mass index, and profession (p = 0.01, p = 0.02, p = 0.01) Conclusion: Awareness should be increased about cancer screening practices within the scope of primary prevention.
