• As a User, I should be able to enable a snooze/repeat feature for alarms, repeating at 5-minute intervals.

4. User Personas

1. Primary User:

   • Description: Individuals who rely on alarms for daily schedules, including students, professionals, and homemakers.
   • Goals: Manage multiple alarms, customize the app's appearance, and personalize alarm sounds.

5. Visuals Colors and Theme

The tough-clock app will feature a unique and vibrant color palette to enhance user engagement and personalization.

• Background: #F5F5F5 (Soft Gray)
• Surface: #FFFFFF (Pure White)
• Text: #333333 (Dark Charcoal)

These colors are chosen to provide a clean, modern, and visually appealing interface while ensuring readability and accessibility.

6. Signature Design Concept

The tough-clock app will feature a dynamic, interactive clock interface as its signature design concept.

Details:

• Home Page Design:
  The landing page will showcase a 3D animated clock that users can interact with. The clock hands will move in real-time, and users can drag them to set alarm times directly.
• Theme Customization:
  Users can preview theme changes in real-time on the 3D clock interface. For example, selecting a new theme will instantly update the clock's colors, background, and accents.
• Micro-Interactions:
  • When setting an alarm, the clock face will "glow" softly to indicate the selected time.
  • A subtle chime sound will play when an alarm is successfully set.
• Transitions:
  Smooth transitions between pages, with a "flip clock" animation when navigating between alarms and settings.
• Snooze Interaction:
  When the snooze feature is activated, the clock will display a countdown timer in the center, visually indicating the time left until the next alarm.

This design ensures the app is not only functional but also visually captivating and enjoyable to use.
