A React Native application that allows users to create, manage, and interact with multiple customizable timers. The app emphasizes clean UI/UX and minimal third-party dependencies while supporting grouped actions, progress visualization, and local data persistence.
Navigate to the add screen and enter timer details like name, duration, and category.
Timers are shown grouped by their category in collapsible sections.
You can control each timer individually — start, pause, or reset them.
Each timer shows a progress bar to visualize time left.
Use the category header controls to start, pause, or reset all timers within a category.
When a timer finishes, a modal appears with a congratulatory message.
