The '잘지내요' app is designed for individuals living alone, providing a simple and effective way to keep loved ones informed about their well-being. With a user-friendly interface, users can easily send a status update by pressing a button, ensuring family members are reassured about their safety. The app automatically sends a check-in request to pre-registered contacts if the button is not pressed for three consecutive days, facilitating peace of mind for both users and their families.

In addition to its core functionality, '잘지내요' features customizable notification settings that remind users to send their daily status. Alerts can be set to notify users a day, three hours, or one hour before the scheduled message is sent. The app prioritizes user privacy by collecting minimal information solely for the purpose of sending check-in requests, ensuring that personal data is not misused. Note that this app is not a substitute for emergency services and may not function in case of network issues.
