[推荐] 手机应用原型设计工具Fluid UI

Fluid UI （www.fluidui.com）是一款可以跨平台、跨设备开发应用程序设计模型的网页应用程序。各位设计师们，还在为写写画画描绘原型而绞尽脑汁吗？隔壁公司都在用Fluid UI来设计应用程序了，你还在等什么？

Fluid UI对于UX流程设计有很大帮助，能够将不同的界面联立起来，以便于看到产品不同界面之间的关系。

使用过Fluid UI的开发者表示，该工具最吸引自己的地方在于它的“极简主义”。

Fluid UI提供免费版本和付费版本：
免费版――支持1个项目；
29美元/月――支持3个项目；
49美元/月――支持10个项目；
129美元/月――支持10个以上项目。

手机应用UI设计测试平台是一个针对于苹果手机和安卓手机系统UI设计的网站，可以在线通过谷歌浏览器试用Fluid UI，进行一些换肤、位置、图标等测试。

苹果手机和安卓手机的流行也为手机系统的UI设计添加了一把火，想这样的可以在线通过浏览器来调试系统UI的网站少之又少，如果你是手机系统UI的设计师，那么这个网站绝对要去试试了，不过需要注册以后才可以试用，登录后有非常丰富的图标、套图、模版可以在线测试的。

How does it work?
As with all creative tools, you start with a blank canvas. Simply double click to create a page. Within the page settings select the device you are prototyping to change the page size or choose the custom option to input your own dimensions. Currently supports iPhone, iPad, Android, Android tablet and Windows 8.

The editor begins in wireframe mode, other libraries containing over 1000+ widgets can be browsed and added to your pages through the drag and drop interface. Position everything where you please within each page. You can edit most widgets, allowing you to change dimensions, text fields, color and more.

Pages and widgets can easily be brought to life by linking them to other pages within your prototype. Choose the link menu to alter the transition or gesture involved. Gestures supported include tap, tap & hold, double tap and swipes - left, right, up, down. Use these to allow your clients to experience a true native app look and feel from your prototypes.

You can also upload your own images allowing you to create high fidelity personalized mockups. Add your clients logos, images and backgrounds. This also enables users who have premade screenshots to add them to the interface. You can then add invisible hotspots and link any area of the page, thus bringing your screenshots to life. With one click you can then test them on a mobile device.
