Workshop Timer - PRD

A delightful timer application designed specifically for workshop sessions, group work, and collaborative activities that combines practical time management with engaging audio-visual feedback.

Experience Qualities:

  1. Playful - Fun sound effects and celebratory animations create joy and engagement
  2. Focused - Clean, distraction-free interface keeps attention on the task at hand
  3. Intuitive - One-click controls make operation effortless for facilitators and participants

Complexity Level: Light Application (multiple features with basic state)

  • Simple timer functionality with preset options, custom time input, sound selection, and visual effects that enhance workshop facilitation without overwhelming complexity.

Essential Features

Timer Controls

  • Functionality: Set custom time (minutes/seconds) or use quick presets (1, 3, 5, 10, 15 minutes)
  • Purpose: Flexible time management for different workshop activities
  • Trigger: Click preset buttons or input custom values
  • Progression: Select time → Press start → Timer counts down → Audio/visual celebration at completion
  • Success criteria: Timer accurately counts down and stops at zero with appropriate feedback

Audio Feedback System

  • Functionality: Play engaging completion sounds with volume control and mute option
  • Purpose: Clear session endings that grab attention without being jarring
  • Trigger: Timer reaches zero or manual sound testing
  • Progression: Timer ends → Sound plays → Visual effects display → Ready for next session
  • Success criteria: Sounds play reliably across devices with user-controllable volume

Session Management

  • Functionality: Start, pause, resume, reset, and restart with new times
  • Purpose: Handle real-world workshop interruptions and flow changes
  • Trigger: Control button interactions during active or completed sessions
  • Progression: Any state → Action button → Immediate response → Updated timer state
  • Success criteria: All state transitions work smoothly without losing progress

Visual Celebration

  • Functionality: Confetti or particle effects when timer completes
  • Purpose: Create positive reinforcement and energy for completing focused work
  • Trigger: Timer completion alongside audio feedback
  • Progression: Timer hits zero → Audio + visual effects → 3-second celebration → Ready state
  • Success criteria: Effects display smoothly and enhance rather than distract from the completion moment

Edge Case Handling

  • Browser tab switching: Timer continues running in background and shows correct remaining time when returning
  • Audio playback failure: Graceful fallback with visual-only notification if sound system unavailable
  • Rapid clicking: Debounced controls prevent multiple simultaneous actions or state conflicts
  • Invalid time input: Input validation prevents negative values or impossibly large times
  • Mobile orientation changes: Responsive layout maintains usability in portrait and landscape modes

Design Direction

The design should feel energetic and welcoming while maintaining professional workshop credibility - think modern presentation tool meets game interface with clean typography and purposeful use of color to guide attention to the most important information (remaining time).

Color Selection

Complementary (opposite colors) - Using energetic blue-orange pairing to create visual interest while maintaining clear hierarchy.

  • Primary Color: Vibrant Blue oklch(0.6 0.25 250) - Conveys focus, reliability, and calm productivity
  • Secondary Colors: Soft grays oklch(0.95 0.01 250) for backgrounds, oklch(0.7 0.02 250) for subtle elements
  • Accent Color: Warm Orange oklch(0.75 0.18 50) - Draws attention to active states, completion, and primary actions
  • Foreground/Background Pairings:
    • Background (Light Gray oklch(0.98 0.005 250)): Dark Blue text oklch(0.25 0.08 250) - Ratio 8.1:1 ✓
    • Primary (Vibrant Blue oklch(0.6 0.25 250)): White text oklch(0.98 0.005 250) - Ratio 6.2:1 ✓
    • Accent (Warm Orange oklch(0.75 0.18 50)): Dark Blue text oklch(0.25 0.08 250) - Ratio 5.8:1 ✓
    • Card (Pure White oklch(1 0 0)): Dark Blue text oklch(0.25 0.08 250) - Ratio 9.1:1 ✓

Font Selection

Typography should feel modern and highly legible for quick time reading, with strong numerical hierarchy that makes remaining time instantly scannable from across a room.

  • Typographic Hierarchy:
    • H1 (Timer Display): Inter Bold/4rem/tight letter spacing - Maximum impact for remaining time
    • H2 (Section Headers): Inter SemiBold/1.5rem/normal spacing
    • Body (Controls/Labels): Inter Regular/1rem/relaxed spacing
    • Small (Status/Settings): Inter Medium/0.875rem/normal spacing

Animations

Motion should feel celebratory and energizing during completions while remaining subtle during active timing to avoid distraction from the work at hand.

  • Purposeful Meaning: Smooth state transitions build confidence in the tool's reliability, while completion celebrations create positive reinforcement for productive work sessions
  • Hierarchy of Movement: Timer completion gets the most dramatic animation (confetti + sound), control interactions get subtle feedback, and running timer has minimal motion to avoid distraction

Component Selection

  • Components: Card for main timer container, Button variants for controls (primary for start/pause, secondary for reset), Input for custom time entry, Slider for volume control, Select for sound choice, Badge for status indicators
  • Customizations: Large-scale timer display component, confetti particle system, audio manager with Web Audio API integration, preset time button grid
  • States: Buttons show clear idle/hover/active/disabled states, timer display changes color based on remaining time (normal/warning/complete), sound controls indicate mute/volume levels
  • Icon Selection: Play/Pause from Phosphor Icons, Volume/VolumeX for audio controls, Clock for timer, Confetti for celebration mode, ArrowCounterClockwise for reset
  • Spacing: Generous padding (p-6/p-8) around main timer, consistent gap-4 for control groups, gap-2 for inline elements, mt-6 for section separation
  • Mobile: Timer display scales down gracefully, preset buttons arrange in responsive grid (2-3 columns on mobile, 4-6 on desktop), controls stack vertically on narrow screens with larger touch targets (min-h-12)
