Employee attendance includes hours of entry and completion of work, while leave includes maternity leave, sick leave, annual leave, and leave for important reasons. The employee attendance and leave application development uses Android operating system based programming used in smartphones. By using the SWOT analysis method (Strength, Weakness, Opportunity, Threat) the problems that occur in the existing system are procedures for approval of attendance and leave which are still carried out outside the existing system.
