About this app

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 PrototypesšŸŒŸ
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 PerfectšŸ“
Crystal automagicallyā„¢ļø 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 DocumentsšŸ’¾
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.

Perfect!! Thanks for giving back artboard scroll. I just found another potential issue. Not exactly sure if this is an issue. When I have elements that I've marked as "fixed position when scrolling", when I test my screen to try scroll, it makes a copy of those fixed elements. I can send a short video if you want.

Hi Yogesh, thatā€™s strange indeed. If you could send a video to me at support@smithyproductions.co.uk that would help a lot. Rory

Great app that works really well for viewing sketch artboards on Android. But there are couple issues that prevent me from giving 5 stars. First, the app seems to launch by itself, when youre doing something else. I have to uninstall the app to prevent it from popping up all the time. Second, it doesnt always find my computer on my Wifi, but that might just be a weird issue with my work network.

The flickering of the art board has gotten a lot better. Fixed-position layers on Sketch are staying still upon scrolling, when an art board template is applied on Sketch. It's great! Almost just like Sketch Mirror. Sometimes the art boards take ages to load though. Not sure what's going on there, but I just restart the app.
