Top Flutter Stopwatch, Timer and Countdown packages

Last updated: May 18, 2026

Stopwatches, timers, and countdowns are essential for fitness apps, productivity tools (like Pomodoro timers), and time-limited quiz games.

Best Practices for Timers

  • Background Accuracy: Dart Timer objects do not run accurately when an app is backgrounded by the OS. Always save the exact DateTime.now() timestamp when the app goes to the background, and calculate the elapsed time when it resumes.
  • UI Decoupling: Never tie your core timer logic directly to UI ticks. The core logic should run independently, simply notifying the UI to repaint the current value via a Stream or ValueNotifier.
  • Formatting: Use dedicated packages to format raw milliseconds into readable formats like HH:mm:ss.SS to prevent writing complex modulo math from scratch.

The complete list of Stopwatch, Timer, Countdown, and Time Formatting packages for Flutter is provided below.
