Background: Technological solutions can enhance health-related behaviors, knowledge, and attitudes. The field of family planning can effectively utilize this technology.

Objective: To evaluate the impact of an interactive mobile phone application on family planning services.

Materials and methods: A quasi-experimental design was used; the intervention group received routine postpartum contraceptive counseling in addition to an introduction to a family planning application, which they installed on their mobile phones. Conversely, the control group received only the routine contraceptive counseling without any mention of the application. This study utilized various validated instruments, including a contraception knowledge assessment tool, a contraception attitude scale, a mobile application assessment tool, and a decision conflict scale.

Results: The study revealed significant differences (p <.05) in the use of contraceptive methods starting from the first six weeks after birth, in the continuity of the use of modern methods within the first six months after birth, and in the decision-making process. On the other hand, there were no significant differences (p >.05) in the occurrence of pregnancy within the first six months, use of contraceptive methods in six months, switching between modern and traditional methods, or vice versa.

Conclusion: Interactive mobile phone applications will improve family planning services by promoting early contraceptive use after birth, ensuring continuity of modern methods, and enhancing method selection.

Implications for nurses: Mobile phone applications provide a fordable counseling method that can improve family planning services by minimizing the need for printed materials and transportation compared to individual or group counseling sessions.
