• Dart Timer for precise countdown implementation
• Local storage for saving custom presets and settings
• Responsive design adapting to different screen sizes
• Wake lock to prevent screen timeout during games

Challenges & Solutions

Maintaining timing accuracy while handling rapid button presses required implementing debouncing and ensuring timer updates didn't accumulate errors over long games.

Creating an interface that's both aesthetically pleasing and functional during intense time pressure was solved through user testing and iterative design improvements.
