About Crystal

Start previewing your designs from Sketch in realtime on your Android device!

Open the app and find your computer on your local wifi network. Click to connect and you're mirroring artboards straight away, without any companion Mac app!

If you're on flaky connection or corporate network, fear not, as USB support is provided with a helping hand from the Crystal Mac app. Download the app from https://crystal.smithy.productions/#companion and carry on using Crystal as normal over a cable.

Crystal will always be free, but you're welcome to donate if you appreciate the work design + development that's gone into this. That's the only reason for the in-app purchases - none of the app is locked behind a paywall.


This is a companion app for a Mac design app called Sketch (sketchapp.com). Trying to use it for anything else, like watching movies, playing games or browsing the web will probably result in a sub-par experience.

Since Sketch 43 until now (44) i think there's a bug ini Crystal when you switch screen from sketch to others, Crystal will shown black blank page. Even get back to Sketch, the Crystal preview still blank. I already update to Crystal latest version, nothing change. I must close Crystal first and clear app history and open the app to make work again. Please fix this annoying bug.

Really wanted this to work, but it crashes everytime I load my artboard. Crystal at least connects to Sketch and shows a thumbnail of my artboard, but when I tap on it, it spins and crashes everytime. Will happily raise rating when they improve the robustness of their code. Unusable as it is now -- never got my artboard to show even once.

Isn't working. Useless....Done all the recommendations to get it up and running. Even emailed the developers. It's been searching for 2 days. No luck thus far. So disappointed after waiting for it for so long to become available on Android. Uninstalling it for the 10th and last time. Never had I had so much hassle installing an app. Do this.....do that. Get this... get that installed. Too bloody complicated.I'll be back one day when you fix all the issues.

Simply get the job done, but connected to crystal is slow, artboards take time to load even sometimes is not loaded. With more improvements crystal will be very useful

Had high hopes and started well but have to agree with a previous review. Connection over both WiFi and USB is ponderously slow. Many artboards don't even load. Happy to change the rating if the developer rectified these issues and make it unuseable.

Undoubtedly the best app for Android. Incredibly useful.

Hate to leave bad reviews, but after the update things got even worse. I've just wasted to much time trying to connect, disconnect, uninstall, reinstall, clear cache, reboot, WiFi, USB, nothing. I'll change the rating with pleasure if the app will be usable again

Edit: Dev updated app and it now works perfectly! Thank you! My artboards aren't loading. I just see spinners. Tried connecting and reconnecting, but to no avail.

Amazing alternative to Sketch Mirror!

Works perfectly but in WiFi connection the app struggles to load large artboards, waiting for the fix. Thank you for giving us this for free.

Finally someone who knows what they are doing wrote an app for a majority of people that don't have iPhones. I gave 4 stars due to there being room for improvement (speed mainly) but for what it does, it is fantastic and the creator deserves a beer (or 3)!

Urmm this app is not working for me. The loading spinner keeps spinning but I can't see my artboards.

M70%
by M####:

Connectivity issues sometimes, but manageable enough to be worth 5 stars. It's always quite different what you see on a desktop screen and what you see on the phone.

we design apps for all generations of android phones as not all our users have the latest smart phone android 5 and up isn't very helpful for designers/devs trying to see how this translates to older phones
