Stopwatch Accelerated

秒錶加速版，為本書中的遊戲挑戰留出時間。

This App goes together with the series Stopwatch Accelerated Edition. The Stopwatch Accelerated Edition App keeps time for game-based challenges in the book. The chronometer has four default times to select from, but you can personalize the countdown to fit it to your requirements.

Feel free to customize the color of the background, stopwatch and text. You can also select from eight alarm sounds.
