SLAP - 쌈@뽕한 전화 is a social networking app designed for iPhone users to have unique interactions with their closest friends. Users can connect with up to 5 friends within a confined space to enjoy special communication features. One standout feature is the ability to send voice messages and make calls even if the friend's phone is locked, ensuring messages are always received. Additionally, the app keeps a record of the total time spent on calls with friends.

SLAP is tailored for high school and college students, providing a platform for close friends to communicate in their own exclusive space. By using SLAP, users can avoid mixing interactions with family members, teachers, and other acquaintances, focusing solely on communication with their closest friends.
