시그널 is a couple app designed to enhance the dating life of busy individuals. With this app, couples can enjoy a private messenger to have meaningful conversations without the clutter of other messaging apps.

One of the standout features of 시그널 is its shared calendar. Instead of constantly asking each other about schedules, couples can conveniently manage and share their calendars within the app. This eliminates the hassle of coordinating plans and ensures that both partners are on the same page.

Additionally, 시그널 provides a personalized home screen where couples can easily access important information. From each other's schedules to countdowns for special events, the home screen offers a quick glance at all the relevant details. It even allows users to jot down quick notes for easy reference.

The app does not require any mandatory access permissions, ensuring user privacy. However, there is an optional permission to access the device's photo album for sending pictures and videos within the messenger.

For any inquiries or partnerships, users can reach out to the developer via email at
