Presentation Clock — App Store 排名

应用简介

开发者在美国 App Store 的完整简介（英文原文）。

This app does one thing but it does it extremely well. If you give presentations, training, tutorials, or speak publicly, this app is for you. Beautifully animated, with large, easy to read numbers that change colors at thresholds you determine. When the timer hits 0:00, the colors invert (black on red) and continue counting up indicating how long you've gone over. Fully customizable options and simple touch controls * Create and save as many timers as you want * Set time limits for color warnings to change the clock to green, yellow and red * Timers can be configured to give audible and/or vibration alerts when crossing a time limit threshold—but if you want a completely silent countdown, thats ok too :)
