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 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. Unlock certain features and support development by subscribing.

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

Love the app when it works, but unfortunately it seems to be completely unable to connect anymore. I would rather pay for a reliable app that worked consistently than fiddle around with a free app that rarely/never works. I've tried all the troubleshooting steps I've found online and still no luck. (force quitting app, uninstalling/reinstalling, desktop app, pairing my phone with my computer through bluetooth) My device: Pixel 3 (android version 9) Laptop: Macbook Pro (2018, Mojave 10.14.4) Sketch Version: 54.1

Hi James, I'm sorry that Crystal has been flaky in the past. I recently made some major updates, and hope that they have fixed a lot of the connection issues. Have you had a chance to try the latest version? Please let me know at support@smithyproductions.co.uk if you still find any issues! 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.
