Crystal

Say hello to Crystal, the only app you need to preview and prototype Sketch designs. Relied on by teams at Google, Apple and Expedia.

Open Crystal on the same WiFi as your computer and start previewing your designs in realtime. Crystal refreshes on the fly as you modify your artboards in Sketch and auto-switches to your current Sketch artboard. If you're without WiFi or in corporate networks where Crystal can't find Sketch, USB support is provided with the help of the Mac companion app, available at https://crystal.smithy.productions/#companion.

Live Prototypes🌟

Swipe between adjacent artboards or prototype using clickable elements to move screens. Crystal fully supports Sketch prototyping, including transition animations and Android back button navigation. Finally you can preview mobile app designs on the devices they're made for.

Pixel Perfect📏

Crystal automagically™️ fetches scaled artboards, so that your designs match the pixel density of your device. Tablets are fully supported, and include the ability to view artboards fullscreen or at phone-scale.

Download Documents💾

Easily save any Sketch documents to your device for offline access without Sketch. Untether yourself from your computer and demo your designs to others with full offline prototyping support.

Note: Crystal is a companion app for Sketch and requires it to function. Trying to use it for anything else, like watching movies, playing games or browsing the web will probably result in a sub-par experience. Crystal is free for everyone.

向Crystal问好，您是预览和设计Sketch设计原型的唯一应用。 Google，Apple和Expedia的团队依赖。

在与计算机相同的WiFi上打开Crystal，然后开始实时预览设计。在Sketch中修改画板并自动切换到当前Sketch画板时，Crystal会即时刷新。如果您没有WiFi或在Crystal无法找到Sketch的公司网络中，则可在Mac配套应用程序的帮助下获得USB支持，网址为https://crystal.smithy.productions/#companion。

实时原型🌟

使用可点击的元素在相邻的画板或原型之间滑动以移动屏幕。 Crystal完全支持Sketch原型，包括过渡动画和Android后退按钮导航。最后，您可以在制造它们的设备上预览移动应用程序设计。

像素完美📏

Crystal automagically™️可获取缩放的画板，以便您的设计与设备的像素密度相匹配。平板电脑受到完全支持，并具有全屏或手机级查看画板的功能。

下载文档💾

无需使用Sketch，即可将任何Sketch文档轻松保存到设备中以供离线访问。借助完整的离线原型支持，将自己从计算机上解脱出来，并将您的设计演示给其他人。

注意：Crystal是Sketch的配套应用，需要它起作用。尝试将其用于其他任何用途，例如看电影，玩游戏或浏览网络，都可能会带来低于标准的体验。水晶对所有人免费。订阅即可解锁某些功能并支持开发。
