Due to the importance and value of personal location information in recent years, a number of location-based services(LBS) have been launched, and many popular LBS are based on mobile applications, thanks to the popularization of phones with satellite navigation devices. However, since many users of LBS have experienced various side effects that come from the convenience of having a phone, regardless of time and place, the side effects could become a big social issue. Not only one of them, the steady occurrence of a large amount of information leakage, has led users to deviate from LBS, but also inconvenience and dislike that come from quality of the services has done. Therefore, this paper first analyzes the problems of existing personal location-sharing applications. And we demonstrate that we can implement a new personal location-sharing application considering the user experience(UX) by using the interface and system of telephone service found in the analysis process.
