Designed for Android Wear but also works on other devices.

Couldn't be easier! Instructions:

1. Start app

2. Tap screen when you see a lightning

3. Tap again when you hear the thunder

For a more immersive experience, after tapping the screen once, the calculation is shown in real time. After tapping the screen the second time a highly accurate distance is displayed.

Designed to be as simple and lightweight as possible.

专为Android Wear，但也适用于其他设备。

再简单不过了！说明：

    1.启动应用程序

    2.点击屏幕上，当你看到闪电

    3.点击一次，当你听到雷声

对于一个更加身临其境的体验，点击屏幕后一次，计算是实时显示。点击屏幕，第二次后会显示一个非常精确的距离。

设计得简单，重量轻越好。
